XSLT <xsl:for-each> Element
The <xsl:for-each> element allows you to do looping in
XSLT.
The <xsl:for-each> Element
The XSL <xsl:for-each> element can be used to select every XML
element of a specified node-set:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-each select="catalog/cd">
<tr>
<td><xsl:value-of select="title"/></td>
<td><xsl:value-of select="artist"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
|
Note: The value of the select attribute is an XPath
expression.
An XPath expression works like navigating a file system; where a forward slash (/) selects subdirectories.
The result of the transformation above will look like this:

Filtering the Output
We can also filter the output from the XML file by adding a criterion to the
select attribute in
the <xsl:for-each> element.
<xsl:for-each select="catalog/cd[artist='Bob Dylan']">
Legal filter operators are:
- = (equal)
- != (not equal)
- < less than
- > greater than
Take a look at the adjusted XSL style sheet:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<td><xsl:value-of select="artist"/></td>
