XSLT <xsl:variable> Element
 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!
Syntax
<xsl:variable
name="name"
select="expression">
<!-- Content:template -->
</xsl:variable>

Attributes
| 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
The following example adds a value to the variable "header" by the content of the <xsl:variable>
element:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="header">
<tr>
<th>Element</th>
<th>Description</th>
</tr>
</xsl:variable>
<xsl:template match="/">
<html>
<body>
<table>
<xsl:copy-of select="$header" />
<xsl:for-each select="reference/record">
<tr>
<xsl:if category="XML">
<td><xsl:value-of select="element"/></td>
<td><xsl:value-of select="description"/></td>
</xsl:if>
</tr>
</xsl:for-each>
</table>
<br />
<table>
<xsl:copy-of select="$header" />

<tr>

<td><xsl:value-of select="description"/></td>
</xsl:if>
</tr>
