XSLT current() Function


XSLT Function Reference 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.


Syntax
