starts-with Function
Returns true if the first argument string starts with the second argument string; otherwise returns false.
boolean starts-with(string, string)
Remarks
If an argument is not of type string, it is first converted to a string and then evaluated. The function is case-sensitive.
Example
The following example illustrates how to use the starts-with()
function to query a collection of books whose title begins with a capital letter "W".
XML FILE (starts-with.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 (starts-with.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="starts-with(title, 'W')"> <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>
