Returns True if the xml:langattribute of the context node is the same as a sublanguage of the language specified by the argument string.

Syntax 

		
boolean lang(
string)

Parameters

string

A string specifying a language.

Return Value

Returns True if the xml:langattribute of the context node is the same as a sublanguage of the language specified by the argument string.

Remarks

The language of the context node is determined by the value of the xml:langattribute on the context node, or if the context node has no xml:langattribute, by the value of the xml:langattribute on the nearest ancestor of the context node that has an xml:langattribute. If there is no such attribute, lang()returns False. If there is such an attribute, lang()returns True if the attribute value is equal to the argument (ignoring case) or if there is a suffix starting with " -", such that the attribute value is equal to the argument, ignoring the suffix of the attribute value and ignoring case.

Given the following XML elements:

Copy Code 
<para xml:lang="en"/>
<div xml:lang="en"><para/></div>
<para xml:lang="EN"/>
<para xml:lang="en-us"/>

The following function call returns True for all.

Copy Code 
lang("en")
