Description
-
A node's language is determined by its
xml:lang
attribute. If the current node does not have anxml:lang
attribute, then the value of thexml:lang
attribute of the nearest ancestor that has anxml:lang
attribute will determine the current node's language. If the language cannot be determined (no ancestor has anxml:lang
attribute), this function will return false. -
If the given
string
does not specify a country code, this function will match nodes of that language with any country code. The converse is not true.
Given this fragment of XML:
<p xml:lang="en">I went up a floor.</p>
<p xml:lang="en-GB">I took the lift.</p>
<p xml:lang="en-US">I rode the elevator.</p>
And this part of an XSL template:
<xsl:value-of select="count(//p[lang('en')])" />
<xsl:value-of select="count(//p[lang('en-GB')])" />
<xsl:value-of select="count(//p[lang('en-US')])" />
<xsl:value-of select="count(//p[lang('de')])" />
The output might be:
