"template" - The Template Declaration Element

This section describes the 'template' element, which declares a transformation template that can be used to generate output text when applied to any matching source elements.

"template": A top-level element inside the "stylesheet" element in an XSLT stylesheet file. A "template" element serves as the template declaration statement.

A "template" element defines an XML transformation template with an XPath expression to match elements in the source XML document. A "template" element also provides result text for the resulting document.

When the transformation engine is processing a source element that matches the XPath expression of a template, the result text of the template will be inserted into the resulting document.

The syntax of the "template" element is:

<xsl:template match="pattern">

"pattern" in a template element is an XPath expression used to match parts in the source XML file. For example, match="p" provides a pattern that matches any element with element name of "p" in the current context.

"content" in a template element is a string expression to be evaluated as the result text for the resulting document. "content" can be a mixture of:

If an element in the source XML file matches a template in stylesheet, the entire source element will be considered as processed as soon as the result text is generated. The entire source element means everything starting from "<" of the starting tag to ">" of the ending tag, including the element name, all attributes, text content, and all sub-elements.

For example, the following template is defined with pure #PCDATA as its content:

<xsl:template match="p">
 Literal text as template content.

To test the above template, I wrote this source XML document:

<p a="v">
 Some text with a <c>child element</c>.

If the above template is applied, the transformation engine will match the element "p" in the source XML document with the defined template, and insert template's content into the result document:

 Literal text as template content.

When this is done, the transformation engine will skip the child element "c" and the attribute "a".
