XSLT current() Function
Complete XSLT Function Reference
Definition and Usage
The current() function returns a node-set that contains only the current node.
Usually the current node and the context node are the same.
<xsl:value-of select="current()"/>
is equal to
<xsl:value-of select="."/>
However, there is one difference. Look at the following XPath expression: "catalog/cd".
This expression selects the <catalog> child nodes of the current node,
and then it selects the <cd> child nodes of the <catalog> nodes. This
means that on each step of evaluation, the "." has a different meaning.
The following line:
<xsl:apply-templates select="//cd[@title=current()/@ref]"/>
will process all cd elements that have a title attribute with value equal to
the value of the current node's ref attribute.
This is different from
<xsl:apply-templates select="//cd[@title=./@ref]"/>
that will process all cd elements that have a title attribute and a ref
attribute with the same value.
