XPath to select all nodes with attributes that contain a sub-string?

XmisterIS · 02-09-2012, 06:30 PM

Quoting from http://www.w3schools.com/xpath/xpath_syntax.asp:

Quote:

//title[@lang='eng']

Selects all the title elements that have an attribute named lang with a value of 'eng'

But what syntax do I use to select all the title elements that have an attribute named lang with a value that contains the substring 'eng'?

You would use the contains function. Example:

document_1.xml

Code:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="application/xml" href="document_1.xslt"?>
<document>
	<title>Title 1</title>
	<title lang="eng">Title 2</title>
	<title lang="eng-US">Title 3</title>
	<title lang="eng-Latn-US">Title 4</title>
</document>

document_1.xslt

Code:

<?xml version="1.0" encoding="UTF-8"?>
<stylesheet xmlns="http://www.w3.org/1999/XSL/Transform" xmlns:xslt="http://www.w3.org/1999/XSL/Transform" version="1.0">
	<output media-type="application/xhtml+xml"/>
	<template match="/">
		<html xmlns="http://www.w3.org/1999/xhtml">
			<head>
				<title>Demo Document</title>
				<style>
					* { margin: 0; padding: 0; }
					html { margin: 2em; }
					h1 { font-size: 1em; }
					ol { margin: 0.25em 0 1em; padding-left: 1em; }
				</style>
			</head>
			<body>
				<h1>English Titles</h1>
				<ol>
					<xslt:for-each select="child::document/child::title[contains(attribute::lang, 'eng')]">
					<!-- child::document/child::title[contains(attribute::lang, 'eng')] = document/title[contains(@lang, 'eng')] -->
						<li><xslt:value-of select="self::node()"/></li>
					</xslt:for-each>
				</ol>
			</body>
		</html>
	</template>
</stylesheet>

Okay, apparently the code above needs a bit of modification:

Code:

<output media-type="application/xhtml+xml"/>

must be

Code:

<output method="xml" media-type="application/xhtml+xml"/>

for this code to work in Internet Explorer 9 because that browser does not implement section 16 of the XSLT 1.0 spec correctly.
