## **Overview**

Aspose.Slides for C++ can convert PowerPoint presentations to the PowerPoint XML Presentation format. XML output is useful when you need a text-based representation for inspecting presentation structure, troubleshooting generated documents, comparing output in automated tests, or integrating with a workflow that consumes XML instead of a presentation package.

Use the [Presentation::Save](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/save/) method with the `Xml` value from the [SaveFormat](https://reference.aspose.com/slides/cpp/aspose.slides.export/saveformat/) enumeration. You can write the result directly to a file or to a stream.

`SaveFormat::Xml` creates a PowerPoint XML Presentation. It does not extract the individual Office Open XML parts stored inside a PPTX package. If you need the exact PPTX package parts, such as `ppt/presentation.xml` or individual slide XML files, inspect the PPTX package itself.

## **Convert a Presentation to an XML File**

Load a source presentation with the [Presentation](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/) class, and then pass the output path and `SaveFormat::Xml` to [Presentation::Save](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/save/). The source can be any presentation format supported for loading, such as PPT, PPTX, or ODP.

The following example converts a PPTX presentation to an XML file:

```cpp
#include <DOM/Presentation.h>
#include <Export/SaveFormat.h>
#include <system/object_ext.h>

using namespace Aspose::Slides;
using namespace Aspose::Slides::Export;

auto presentation = System::MakeObject<Presentation>(u"presentation.pptx");
presentation->Save(u"presentation.xml", SaveFormat::Xml);
presentation->Dispose();
```

## **Write the XML Output to a Stream**

Use the stream overload of [Presentation::Save](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/save/) when the XML must remain in memory or be passed to another component, such as a web service, storage provider, or XML processing pipeline. The following example writes the result to a [MemoryStream](https://reference.aspose.com/slides/cpp/system.io/memorystream/) and rewinds it for subsequent reading:

```cpp
#include <DOM/Presentation.h>
#include <Export/SaveFormat.h>
#include <system/io/memory_stream.h>
#include <system/object_ext.h>

using namespace Aspose::Slides;
using namespace Aspose::Slides::Export;
using namespace System::IO;

auto presentation = System::MakeObject<Presentation>(u"presentation.pptx");
auto xmlStream = System::MakeObject<MemoryStream>();

presentation->Save(xmlStream, SaveFormat::Xml);
xmlStream->set_Position(0);
presentation->Dispose();

// Pass xmlStream to the next component in the workflow.
```

## **Compare XML with Presentation and Export Formats**

Choose the output format according to how the result will be used:

| Format | Output | Typical use |
| --- | --- | --- |
| PowerPoint XML (`.xml`) | A PowerPoint XML Presentation | Inspecting structure, troubleshooting, comparing generated output, and XML-based integration |
| PPT (`.ppt`) | A legacy binary presentation file | Compatibility with older PowerPoint workflows |
| PPTX (`.pptx`) | An Office Open XML package containing multiple parts | Regular PowerPoint editing and presentation exchange |
| PDF or TIFF | Fixed-layout pages or a multi-page image | Viewing, printing, and archiving |
| PNG, JPEG, or SVG | A rendered representation of an individual slide | Thumbnails, previews, and image assets |
| HTML or HTML5 | Web-oriented presentation output | Browser viewing and web publishing |

Unlike PPT and PPTX, XML output is primarily intended for inspection and data-oriented workflows. Unlike PDF, TIFF, HTML, and slide image formats, it represents presentation data rather than rendering slides as pages or visual assets. The [supported file formats](/slides/cpp/supported-file-formats/) table lists PowerPoint XML Presentation as a save-only format, so do not use it when a workflow must load the exported file back into Aspose.Slides for continued editing.

## **FAQ**

**Is `SaveFormat::Xml` the same as saving a PPTX file?**

No. PPTX is a package containing multiple Office Open XML parts, whereas `SaveFormat::Xml` creates a PowerPoint XML Presentation file.

**Can I save the XML output without creating a file on disk?**

Yes. Pass a writable stream to [Presentation::Save](https://reference.aspose.com/slides/cpp/aspose.slides/presentation/save/). For example, use a [MemoryStream](https://reference.aspose.com/slides/cpp/system.io/memorystream/) for in-memory processing.

**Can Aspose.Slides load the exported XML file again?**

No. PowerPoint XML Presentation is currently supported for saving but not for loading. Use PPTX or another supported presentation format when round-trip editing is required.

**Does XML conversion render each slide as a page or image?**

No. XML conversion writes structured presentation data. Use PDF or TIFF for page-oriented output, or PNG, JPEG, and SVG for individual slide images.
