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

Back

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"/>

Attributes

Attribute Value Description
elements list-of-element-names

Required. A white space separated list of element names for which white space should be preserved/removed.

Note: The list can also contain "*" and "prefix:*" so that all elements or all elements from a particular namespace can be joined

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">
    <p>
    <xsl:value-of select="title" /><br />
    <xsl:value-of select="artist" /><br />
    <xsl:value-of select="country" /><br />
    <xsl:value-of select="company" /><br />
    <xsl:value-of select="price" /><br />
    <xsl:value-of select="year" />
    </p>
  </xsl:for-each>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>
