XML에서 PDF 생성

다음 코드 스니펫은 Aspose.PDF.Drawing 라이브러리와 함께 작동합니다.

XML 문서에서 PDF 문서를 생성하는 것은 XML 문서가 다양한 내용을 설명할 수 있기 때문에 간단한 작업이 아닙니다. Aspose.PDF for .NET는 XML 문서를 기반으로 PDF를 생성하는 여러 가지 방법을 제공합니다:

• XSLT 변환 사용
• XSL-FO (XSL Formatting Objects) 마크업 사용
• 자체 Aspose.PDF XML 스키마 사용

XSLT 변환을 사용하여 PDF 문서 생성

XSL (eXtensible Stylesheet Language)은 XML 문서를 다른 XML 문서나 HTML로 변환하기 위한 스타일링 언어입니다. 우리의 경우 XML을 HTML로 변환한 다음 HTML 데이터를 기반으로 PDF를 생성할 수 있습니다.

간단한 CD 카탈로그가 포함된 XML 파일이 있다고 가정해 보겠습니다 (아래 참조).

이 파일을 PDF로 변환하려면 HTML 레이아웃이 있는 XSL을 생성해야 합니다. 데이터를 테이블로 렌더링해 보겠습니다. 이를 도와줄 XSL 파일은 다음과 같을 수 있습니다:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <html>
      <body>
        <h2>My CD Collection</h2>
        <table border="1">
          <tr bgcolor="#9acd32">
            <th style="text-align:left">Title</th>
            <th style="text-align:left">Artist</th>
          </tr>
          <xsl:for-each select="catalog/cd">
            <tr>
              <td>
                <xsl:value-of select="title"/>
              </td>
              <td>
                <xsl:value-of select="artist"/>
              </td>
            </tr>
          </xsl:for-each>
        </table>
      </body>
    </html>
  </xsl:template>
</xsl:stylesheet>

따라서 XML을 변환하고 PDF 문서에 로드해야 합니다. 다음 예제는 이 방법을 보여줍니다:

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXsltToPdf()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    var XmlContent = File.ReadAllText(dataDir + "XMLFile1.xml");
    var XsltContent = File.ReadAllText(dataDir + "XSLTFile1.xslt");
    var options = new Aspose.Pdf.HtmlLoadOptions();

    // set page size to A5
    options.PageInfo.Height = 595;
    options.PageInfo.Width = 420;

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(TransformXmlToHtml(XmlContent, XsltContent), options))
    {
        // Save PDF document
        document.Save(dataDir + "XSLT_out.pdf");
    }
}

public static MemoryStream TransformXmlToHtml(string inputXml, string xsltString)
{
    var transform = new XslCompiledTransform();

    using (var reader = XmlReader.Create(new StringReader(xsltString)))
    {
        transform.Load(reader);
    }

    var memoryStream = new MemoryStream();
    var results = new StreamWriter(memoryStream);

    using (var reader = XmlReader.Create(new StringReader(inputXml)))
    {
        transform.Transform(reader, null, results);
    }

    memoryStream.Position = 0;
    return memoryStream;
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXsltToPDF()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    var XmlContent = File.ReadAllText(dataDir + "XMLFile1.xml");
    var XsltContent = File.ReadAllText(dataDir + "XSLTFile1.xslt");
    var options = new Aspose.Pdf.HtmlLoadOptions();

    // set page size to A5
    options.PageInfo.Height = 595;
    options.PageInfo.Width = 420;

    // Open PDF document
    using var document = new Aspose.Pdf.Document(TransformXmlToHtml(XmlContent, XsltContent), options);

    // Save PDF document
    document.Save(dataDir + "XSLT_out.pdf");
}

public static MemoryStream TransformXmlToHtml(string inputXml, string xsltString)
{
    var transform = new XslCompiledTransform();

    using var reader1 = XmlReader.Create(new StringReader(xsltString));
    transform.Load(reader1);

    var memoryStream = new MemoryStream();
    var results = new StreamWriter(memoryStream);

    using var reader2 = XmlReader.Create(new StringReader(inputXml));
    transform.Transform(reader2, null, results);

    memoryStream.Position = 0;
    return memoryStream;
}

XSL-FO 마크업을 사용하여 PDF 문서 생성

XSL-FO는 XML 데이터를 화면, 종이 또는 기타 매체로 출력하기 위한 형식을 설명하는 XML 기반 마크업 언어입니다. Aspose.PDF에는 XSL-FO 마크업을 적용하고 PDF 문서를 얻을 수 있는 특별한 클래스가 있습니다.

예를 들어 보겠습니다. 다음은 직원의 샘플 데이터가 포함된 XML 파일입니다.

<?xml version="1.0" encoding="utf-8" ?>
<employees>
    <companyname>ABC Inc.</companyname>
    <employee>
        <id>101</id>
        <name>Andrew</name>
        <designation>Manager</designation>
    </employee>

    <employee>
        <id>102</id>
        <name>Eduard</name>
        <designation>Executive</designation>
    </employee>

    <employee>
        <id>103</id>
        <name>Peter</name>
        <designation>Executive</designation>
    </employee>
</employees>

직원 데이터를 테이블로 변환하기 위해 또 다른 파일인 XSL-FO 마크업 파일을 생성해 보겠습니다.

                            <fo:table-body>
                                <xsl:apply-templates select="employee"/>

</xsl:stylesheet>

Aspose.PDF에는 XSL-FO 변환을 적용할 수 있는 특별한 XslFoLoadOptions 클래스가 있습니다. 다음 스니펫은 위에서 설명한 샘플 파일과 함께 이 클래스를 사용하는 방법을 보여줍니다.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdf()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Instantiate XslFoLoadOption object
    var options = new Aspose.Pdf.XslFoLoadOptions(dataDir + "employees.xslt");

    // Open XML file
    using (var document = new Aspose.Pdf.Document(dataDir + "employees.xml", options))
    {
        // Save PDF document
        document.Save(dataDir + "XSLFO_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdf()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Instantiate XslFoLoadOption object
    var options = new Aspose.Pdf.XslFoLoadOptions(dataDir + "employees.xslt");

    // Open XML file
    using var document = new Aspose.Pdf.Document(dataDir + "employees.xml", options);

    // Save PDF document
    document.Save(dataDir + "XSLFO_out.pdf");
}

XSL-FO 마크업 및 XSL 매개변수를 사용하여 PDF 문서 생성

때때로 XSL:param을 사용해야 합니다. <xsl:param> 요소는 이름으로 매개변수를 설정하고 선택적으로 해당 매개변수의 기본값을 설정합니다.

이전 사례와 동일한 예를 사용하되 약간의 변경(매개변수 추가)을 하겠습니다. 샘플 데이터가 포함된 XML 파일은 변경되지 않고 …

<?xml version="1.0" encoding="utf-8" ?>
<employees>
    <companyname>ABC Inc.</companyname>
    <employee>
        <id>101</id>
        <name>Andrew</name>
        <designation>Manager</designation>
    </employee>

    <employee>
        <id>102</id>
        <name>Eduard</name>
        <designation>Executive</designation>
    </employee>

    <employee>
        <id>103</id>
        <name>Peter</name>
        <designation>Executive</designation>
    </employee>
</employees>

하지만 XSL-FO 마크업 파일에서는 매개변수를 추가합니다: <xsl:param name="isBoldName"></xsl:param> 그리고 이를 Name 열에 적용합니다.

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:fo="http://www.w3.org/1999/XSL/Format" exclude-result-prefixes="fo">

 <xsl:param name="isBoldName"></xsl:param>

 <xsl:template match="employees">

       </fo:table-body>
      </fo:table>
     </fo:block>
    </fo:flow>
   </fo:page-sequence>
  </fo:root>
 </xsl:template>
 <xsl:template match="employee">
  <fo:table-row>
   <xsl:if test="designation = 'Manager'">
    <xsl:attribute name="font-weight">bold</xsl:attribute>
   </xsl:if>
   <fo:table-cell>
    <fo:block>
     <xsl:value-of select="id"/>
    </fo:block>
   </fo:table-cell>

   <fo:table-cell>
    <xsl:if test="$isBoldName='yes'">
     <xsl:attribute name="font-weight">bold</xsl:attribute>
    </xsl:if>
    <fo:block>
     <xsl:value-of select="name"/>
    </fo:block>
   </fo:table-cell>
   <fo:table-cell>
    <fo:block>
     <xsl:value-of select="designation"/>
    </fo:block>
   </fo:table-cell>
  </fo:table-row>
 </xsl:template>
</xsl:stylesheet>

XSL 매개변수를 추가하려면 자체 XsltArgumentList를 생성하고 XslFoLoadOptions에서 속성으로 설정해야 합니다. 다음 스니펫은 위에서 설명한 샘플 파일과 함께 이 클래스를 사용하는 방법을 보여줍니다.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdfParam_21_7()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Instantiate XslFoLoadOption object
    var options = new Aspose.Pdf.XslFoLoadOptions(dataDir + "employees.xslt");

    options.XsltArgumentList = new XsltArgumentList();
    options.XsltArgumentList.AddParam("isBoldName", "", "yes");

    // Open XML file
    using (var document = new Aspose.Pdf.Document(dataDir + "employees.xml", options))
    {
        // Save PDF document
        document.Save(dataDir + "XSLFO_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdfParam_21_7()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Instantiate XslFoLoadOption object
    var options = new Aspose.Pdf.XslFoLoadOptions(dataDir + "employees.xslt");

    options.XsltArgumentList = new XsltArgumentList();
    options.XsltArgumentList.AddParam("isBoldName", "", "yes");

    // Open XML file
    using var document = new Aspose.Pdf.Document(dataDir + "employees.xml", options);

    // Save PDF document
    document.Save(dataDir + "XSLFO_out.pdf");
}

21.7 이전 버전을 사용하는 경우 다음 기술을 사용하십시오:

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdfParam_21_6()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    var xmlContent = File.ReadAllText(dataDir + "employees.xml");
    var xsltContent = File.ReadAllText(dataDir + "employees.xslt");

    var options = new Aspose.Pdf.XslFoLoadOptions();

    // Open XML file
    using (var document = new Aspose.Pdf.Document(TransformXsl(xmlContent, xsltContent), options))
    {
        // Save PDF document
        document.Save(dataDir + "XSLFO_out.pdf");
    }
}

public static MemoryStream TransformXsl(string inputXml, string xsltString)
{
    var transform = new XslCompiledTransform();

    // Create own XsltArgumentList
    var argsList = new XsltArgumentList();
    argsList.AddParam("isBoldName", "", "no");

    using (var reader = XmlReader.Create(new StringReader(xsltString)))
    {
        transform.Load(reader);
    }

    var memoryStream = new MemoryStream();
    var results = new StreamWriter(memoryStream);

    using (var reader = XmlReader.Create(new StringReader(inputXml)))
    {
        transform.Transform(reader, argsList, results);
    }

    memoryStream.Position = 0;
    return memoryStream;
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXslfoToPdf_Param_21_6()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    var xmlContent = File.ReadAllText(dataDir + "employees.xml");
    var xsltContent = File.ReadAllText(dataDir + "employees.xslt");

    var options = new Aspose.Pdf.XslFoLoadOptions();

    // Open XML file
    using var document = new Aspose.Pdf.Document(TransformXsl(xmlContent, xsltContent), options);

    // Save PDF document
    document.Save(dataDir + "XSLFO_out.pdf");
}

public static MemoryStream TransformXsl(string inputXml, string xsltString)
{
    var transform = new XslCompiledTransform();

    // Create own XsltArgumentList
    var argsList = new XsltArgumentList();
    argsList.AddParam("isBoldName", "", "no");

    using var reader1 = XmlReader.Create(new StringReader(xsltString));
    transform.Load(reader1);

    var memoryStream = new MemoryStream();
    var results = new StreamWriter(memoryStream);

    using var reader2 = XmlReader.Create(new StringReader(inputXml));
    transform.Transform(reader2, argsList, results);

Aspose.PDF XML 스키마를 기반으로 PDF 문서 생성

XML에서 PDF 문서를 생성하는 또 다른 방법은 Aspose.PDF XML 스키마를 사용하는 것입니다. 이 다이어그램을 사용하여 HTML에서 테이블 레이아웃을 사용하는 것처럼 페이지 레이아웃을 설명할 수 있습니다. 이 방법의 작동 방식을 좀 더 자세히 살펴보겠습니다.

페이지 정의

기본 매개변수로 페이지를 정의해 보겠습니다. 우리의 페이지는 A4 페이지 크기를 가지며 텍스트 한 조각만 포함됩니다.

<?xml version="1.0" encoding="utf-8" ?>
<Document xmlns="Aspose.Pdf">
  <Page>
    <TextFragment>
      <TextSegment>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla odio lorem, luctus in lorem vitae, accumsan semper lectus. Cras a auctor leo, et tincidunt lacus.</TextSegment>
    </TextFragment>
  </Page>
</Document>

PDF 문서를 생성하기 위해 BindXml 메서드를 사용할 것입니다.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXmlToPdf()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Bind XML file to the document
        document.BindXml(dataDir + "aspose_pdf_demo.xml");

        // Save PDF document
        document.Save(dataDir + "XML_out.pdf");
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void ExampleXmlToPdf()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf();

    // Create PDF document
    using var document = new Aspose.Pdf.Document();

    //Bind XML file to the document
    document.BindXml(dataDir + "aspose_pdf_demo.xml");

    // Save PDF document
    document.Save(dataDir + "XML_out.pdf");
}

새 페이지 크기를 정의하려면 PageInfo 요소를 추가해야 합니다. 다음 예제에서는 A5 페이지 크기와 25mm 및 10mm의 여백을 설정했습니다.

<?xml version="1.0" encoding="utf-8" ?>
<Document xmlns="Aspose.Pdf">
  <Page>
    <PageInfo IsLandscape="true" Height="595" Width="420">
      <Margin Top="70.8661" Bottom="70.8661" Left="28.3465" Right="28.3465" />
    </PageInfo>
    <TextFragment>
      <TextSegment>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla odio lorem, luctus in lorem vitae, accumsan semper lectus. Cras a auctor leo, et tincidunt lacus.</TextSegment>
    </TextFragment>
  </Page>
</Document>

XML 파일에 HtmlFragment 요소 추가

HTML은 XML과 유사한 태그를 포함하고 있으므로 XML 태그 내에 HTML을 작성할 때 파서는 이를 XML 마크업으로 처리하며 단순히 XML 태그로 인식할 수 없습니다. 이 문제는 XML에서 “CDATA” 섹션을 사용하여 해결할 수 있습니다. CDATA 섹션은 파서에 의해 구문 분석되지 않는 텍스트를 포함하며, 다른 말로 하면 XML 마크업으로 처리되지 않습니다. 다음 샘플 XML 템플릿은 CDATA를 사용하여 XML 마크업 내에 HtmlFragment를 추가하는 방법을 보여줍니다.

<?xml version="1.0" encoding="utf-8" ?>
<Document xmlns="Aspose.Pdf">
  <Page id="mainSection">
    <HtmlFragment>
      <![CDATA[
        <font style="font-family:Tahoma; font-size:40px;">This is Html String.</font>
        ]]>
    </HtmlFragment>
  </Page>
</Document>

XML 파일에 Table 요소 추가

Table, Row, Cell 요소는 테이블을 설명하는 데 사용됩니다. 다음 스니펫은 간단한 테이블을 사용하는 방법을 보여줍니다. 이 예제에서는 일부 셀에 Alignment 속성이 있으며 이 속성은 숫자 값을 가집니다:

1. 왼쪽 정렬
2. 가운데 정렬
3. 오른쪽 정렬
4. 양쪽 정렬. 텍스트는 왼쪽 및 오른쪽 여백에 정렬됩니다.
5. 전체 정렬. ‘양쪽 정렬’과 유사하지만 마지막 줄은 ‘양쪽 정렬’ 모드에서만 왼쪽 정렬되고, ‘전체 정렬’ 모드에서는 모든 줄이 왼쪽 및 오른쪽 정렬됩니다.

테이블은 문서 레이아웃에 사용됩니다. 예를 들어 페이지 헤더를 사용자 정의할 수 있습니다. 이 경우 테이블을 사용하여 헤더를 2열로 나누었습니다.

콘텐츠 동적으로 업데이트

BindXML() 메서드는 XML 파일 내용을 로드하는 기능을 제공하며 Document.save() 메서드는 출력을 PDF 형식으로 저장하는 데 사용할 수 있습니다. 그러나 변환 중에 XML 내부의 개별 요소에 접근하고 XML을 템플릿으로 사용할 수도 있습니다. 다음 코드 스니펫은 XML 파일에서 TextSegments에 접근하는 단계를 보여줍니다.

페이지에 그래픽 요소 추가

XML 문서에 이미지 또는 그래프 객체와 같은 추가 요소를 추가할 수 있습니다. 다음 스니펫은 이러한 요소를 문서에 추가하는 방법을 보여줍니다.

<Graph Width="20" Height="20">
  <Circle PosX="30" PosY="30" Radius="10">
    <GraphInfo Color="Red" FillColor="Blue"></GraphInfo>
  </Circle>
</Graph>

<Image File="logo.png" Id = "testImg"></Image>

XML을 PDF로 변환할 때 이미지 경로 설정

다음 XML 템플릿에는 ID “testImg"가 있는 <Image> 태그가 포함되어 있습니다. 코드에서 이미지 경로를 설정하려는 경우 변환 과정에서 XML 템플릿에서 이미지 요소에 접근하고 원하는 주소로 경로를 설정할 수 있습니다.

        document.BindXml(dataDir + "input.xml");

        // Get reference of Image with ID testImg
        var image = (Aspose.Pdf.Image)document.GetObjectById("testImg");

        // Set image file
        image.File = dataDir + "aspose-logo.jpg";

        // Save PDF document
        document.Save(dataDir + "output_out.pdf");
    }
}
