Name
<xsl:key>
Synopsis
<xsl:key name=”name
" match=”pattern
" use=”expression
“/>
Keys are comparable to identifiers in XML. This
element is used in xsl:stylesheet
to create a reference to elements specified by the pattern
and expression values. For example:
<xsl:key name="chap" match="chapter" use="@title"/>
This element creates a key named chap
to identify chapters by title. You can then reference a chapter
with an XPath function such as:
key("chap", "The XSL Language")
