<h1>XSLT <xsl:variable> Element</h1>

<hr />
<h2>Definition and Usage</h2>
<p>The <xsl:variable> element is used to declare a local or global variable.</p>
<p><b>Note:</b> The variable is global if it's declared as a top-level element,
and local if it's declared within a template.</p>
<p><b>Note:</b> Once you have set a variable's value, you cannot change or modify that value!</p>
<p><b>Tip:</b> You can add a value to a variable by the content of the <xsl:variable>
element OR by the select attribute!</p>
<hr />
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<td valign="top">
<pre><xsl:variable
name="name"
select="expression"></pre>
<pre> <!-- Content:template --></pre>
<pre></xsl:variable></pre>
</td>
</tr>
</table>
<h2>Attributes</h2>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<th align="left" valign="top">Attribute</th>
<th align="left" valign="top">Value</th>
<th align="left" valign="top">Description</th>
</tr>
<tr>
<td valign="top">name</td>
<td valign="top">name</td>
<td valign="top">Required. Specifies the name of the variable</td>
</tr>
<tr>
<td valign="top">select</td>
<td valign="top">expression</td>
<td valign="top">Optional. Defines the value of the variable</td>
</tr>
</table>
<h3>Example 1</h3>
<p>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":</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<td valign="top">
<pre><xsl:variable name="color" select="'red'" /></pre>
</td>
</tr>
</table>
<br />
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<td valign="top">
<pre><xsl:variable name="color" select='"red"' /></pre>
</td>
</tr>
</table>
<h3>Example 2</h3>
<p>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: </p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<td valign="top">
<pre><xsl:variable name="j" /></pre>
</td>
</tr>
</table>
<h3>Example 3</h3>
<p>The following example adds a value to the variable "header" by the content of the <xsl:variable>
element:</p>
<table class="ex" cellspacing="0" cellpadding="3" width="100%" border="1">
<tr>
<td valign="top">
<pre><?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"></pre>
<pre><xsl:variable name="header">
<tr>
<th>Element</th>
<th>Description</th>
</tr>
</xsl:variable></pre>
<pre><xsl:template match="/">
