XSLT Context (Dot) Overview
date_range
13-Jan-21
The current context node changes
as an <xsl:apply-templates> instruction
traverses the document hierarchy and as an <xsl:for-each> instruction examines each node that matches an XPath expression. All relative node references are relative to the current
context node. This node is abbreviated “ .” (read: dot) and can be referred to in XPath expressions,
allowing explicit references to the current node.
The following example contains four uses for “.” . The system node
is saved in the system variable for use
inside the <xsl:for-each> instruction,
where the value of “.” will
have changed. The for-each select expression uses “.” to mean the value of the name element.
The “.” is then used to pull
the value of the name element into the <tag> element. The <xsl:if> test then uses “.” to reference
the value of the current context node.
