contains Function
Checks whether the first argument string contains the second argument string.
boolean contains(str1, str2)
Parameters
- str1
- A string that might contain the second argument.
- str2
- A string that might be contained in the first argument.
Return Values
Returns true if the first argument string contains the second argument string. Returns false otherwise.
Remarks
If an argument is not of type string, it is first converted to a string and then evaluated. The contains() function is case-sensitive.
Example
The following example illustrates how to use the contains() function to query a collection of books whose titles contain the word "Pattern".
XML FILE (contains.xml)
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl"
href="contains.xsl"?>
<bookstore>
<book>
<title>The Weather Pattern</title>
<author>Weather Man</author>
<price>100.00</price>
</book>
<book>
<title>Weaving Patterns</title>
<author>Weaver</author>
<price>150.00</price>
</book>
<book>
<title>Speech Pattern</title>
<author>Speaker</author>
<price>15.00</price>
</book>
<book>
<title>Writing Style</title>
<author>Writer</author>
<price>1500.00</price>
</book>
</bookstore>
XSLT FILE (contains.xsl)
<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"
omit-xml-declaration="yes"/>
<xsl:template match="/">
<html>
<head><title>example</title></head>
<body>
<xsl:apply-templates select="//book"/>
</body>
</html>
</xsl:template>
<xsl:template match="book">
<xsl:if test="contains(title, 'Pattern')">
<DIV>
<B><xsl:value-of select="title"/></B> by
<I><xsl:value-of select="author"/></I> costs
<xsl:value-of select="price"/>.
</DIV>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Output
When applied to the XML file (contains.xml), the XSLT style sheet above produces the following output:
