XSLT <xsl:variable> Element

XSLT Element Reference Complete XSLT Element Reference

Definition and Usage

The <xsl:variable> element is used to declare a local or global variable.

Note: The variable is global if it's declared as a top-level element, and local if it's declared within a template.

Note: Once you have set a variable's value, you cannot change or modify that value!

Tip: You can add a value to a variable by the content of the <xsl:variable> element OR by the select attribute!



  <!-- Content:template -->



Attribute Value Description
name name Required. Specifies the name of the variable
select expression Optional. Defines the value of the variable

Example 1

If the select attribute is present, the <xsl:variable> element cannot contain any content. If the select attribute contains a literal string, the string must be within quotes. The following two examples assign the value "red" to the variable "color":

<xsl:variable name="color" select="'red'" />

<xsl:variable name="color" select='"red"' />

Example 2

If the <xsl:variable> element only contains a name attribute, and there is no content, then the value of the variable is an empty string:

<xsl:variable name="j" />

Example 3

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="header">
  <tr bgcolor="#9acd32">

<xsl:template match="/">
  <table border="1">
    <xsl:copy-of select="$header" />
    <xsl:for-each select="catalog/cd">
        <td><xsl:value-of select="title"/></td>
        <td><xsl:value-of select="artist"/></td>
