XSLT current() Function

Definition and Usage

The current() function returns a node-set containing only the current node. Usually, the current node is the same as the context node.

<xsl:value-of select="current()"/>

is equivalent to

<xsl:value-of select="."/>

However, there is a difference. Consider the following XPath expression: "catalog/cd". The expression selects the <catalog> child node of the current node, and then the <cd> child node of the <catalog> node. This means that at each step of the evaluation, "." has a different meaning.

The following line:

&lt;xsl:apply-templates select="//cd[@title=current()/@ref]"/>

will process all cd elements where the value of the title attribute equals the value of the ref attribute of the current node.

Unlike this:

&lt;xsl:apply-templates select="//cd[@title=./@ref]"/>

This will process all cd elements where the title attribute and the ref attribute have the same value.
