XML Pocket Reference, Second Edition

Name

<xsl:value-of>

Synopsis

<xsl:value-of select=”expression“>
   [disable-output-escaping="yes|no"]/>

This extracts a specific value from a source tree. The select attribute is a single pattern-matching expression that resolves to the value of a string, an element, or an attribute:

<xsl:template match="index">
   This index is <xsl:value-of select="@(type)">
   <xsl:apply-templates/>
</xsl:template>

The select attribute extracts the value of an element or attribute in the source tree and prints it verbatim in the result tree. XML special characters (such as & and <) included in the content of this element are escaped (i.e., replaced by character entities) in the output by default. The attribute disable-output-escaping can be set to yes to disable this behavior.
