Template Syntax

Contents
[ ]

A typical template for LINQ Reporting Engine is composed of common document contents and tags that describe the template’s structure and data bindings. You can form these tags using just running text that can occupy multiple paragraphs to be more descriptive.

A tag body must meet the following requirements:

  • A tag body must be surrounded by “«” and “»” character sequences.
  • A tag body must contain only text nodes.
  • A tag body must not be located inside markup document nodes such as StructuredDocumentTag, CustomXmlMarkup, or SmartTag.

A tag body typically consists of the following elements:

  • A tag name
  • An expression surrounded by brackets
  • A set of switches available for the tag, each of which is preceded by the “-“ character
  • An optional comment providing a human-readable explanation ignored by the engine
<<tag_name [expression] –switch1 –switch2 ... // optional_comment >>

Particular tags can have additional elements.

Some tags require closing counterparts. A closing tag has the “/” character that precedes its name. This tag’s name must match to the name of the corresponding opening tag.

<</tag_name>>

Note – Tag body elements are case-sensitive.

During runtime, after a template syntax tag is processed by the engine, it is typically removed. This can lead to a situation where a paragraph containing the tag becomes empty if it has no other content. If such a paragraph is unwanted, it can be optionally removed by the engine (see “Removing Paragraphs Containing Only Template Syntax Tags” for more information).
