XSLT `<xsl:preserve-space>`

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

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	Required/Optional	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

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

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:strip-space elements="price year" />
<xsl:preserve-space elements="title author" />

<xsl:template match="/">
  <html>
  <body>
  <xsl:for-each select="bookstore/book">
    <p>
    <xsl:value-of select="title" /><br/>
    <xsl:value-of select="author" /><br/>
    <xsl:value-of select="price" /><br/>
    <xsl:value-of select="year" />
    </p>
  </xsl:for-each>
  </body>
  </html>
</xsl:template>

</xsl:stylesheet>
