Example

Here is a short example that demonstrates how normalize-space() works:

<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:variable name="newline"> <xsl:text> </xsl:text> </xsl:variable> <xsl:variable name="testString"> <xsl:text> This is a string with lots of whitespace. </xsl:text> </xsl:variable> <xsl:template match="/"> <xsl:value-of select="$newline"/> <xsl:text>Tests of the normalize-space() function:</xsl:text> <xsl:value-of select="$newline"/> <xsl:value-of select="$newline"/> <xsl:text> normalize-space(' Hello, World!')="</xsl:text> <xsl:value-of select="normalize-space(' Hello, World!')"/> <xsl:text>"</xsl:text> <xsl:value-of select="$newline"/> <xsl:text> normalize-space($newline)="</xsl:text> <xsl:value-of select="normalize-space($newline)"/> <xsl:text>"</xsl:text> <xsl:value-of select="$newline"/> <xsl:text> normalize-space($testString)="</xsl:text> <xsl:value-of select="normalize-space($testString)"/> ...
