XSLT document() Function



Definition and Usage

The document() function is used to access nodes in an external XML document. The external XML document must be valid and parsable.

One way to use this function is to look up data in an external document. For example, if we want to find the Celsius value corresponding to a Fahrenheit value, we access a document that contains precomputed values:

<xsl:value-of select="document('celsius.xml')/celsius/result[@value=$value]"/>

Syntax

Parameters

Parameter Description
object Required. Defines the URI of the external XML document.
node-set Optional. Used to resolve relative URIs.
