XSLT <xsl:preserve-space> and <xsl:strip-space> Elements

Complete XSLT Element Reference

Definition and Usage

The <xsl:preserve-space> element is used to define the elements for which white space should be preserved.

The <xsl:strip-space> element is used to define the elements for which white space should be removed.

Note: Preserving white space is the default setting, so using the <xsl:preserve-space> element is only necessary if the <xsl:strip-space> element is used.

Note: The <xsl:preserve-space> element and the <xsl:strip-space> element are top-level elements.

Syntax

<xsl:preserve-space elements="list-of-element-names"/>

<xsl:strip-space elements="list-of-element-names"/>

Example 1

In the example below we preserve white space nodes for title and artist elements, and remove white space nodes for country, company, price, and year elements:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:strip-space elements="country company price year" />
<xsl:preserve-space elements="title artist" />

<xsl:template match="/">
 <html>
 <body>
 <xsl:for-each select="catalog/cd">
 
 <xsl:value-of select="title" /> 
 <xsl:value-of select="artist" /> 
 <xsl:value-of select="country" /> 
 <xsl:value-of select="company" /> 
 <xsl:value-of select="price" /> 
 <xsl:value-of select="year" />
 
 </xsl:for-each>
 </body>
 </html>
</xsl:template>

</xsl:stylesheet>
