XSLT Reference
current-output-uri()
Returns the URI of the current result document being written inside an xsl:result-document instruction.
Syntax
current-output-uri()Description
current-output-uri() returns the URI of the result document currently being written — the href value of the enclosing <xsl:result-document> instruction. Outside an xsl:result-document, it returns the empty sequence.
This is useful for embedding a document’s own URI as metadata within itself, logging which file is being generated, or constructing relative cross-references between generated documents.
Parameters
This function takes no parameters.
Return value
xs:anyURI? — the URI of the current result document, or the empty sequence when called outside xsl:result-document.
Examples
Embed the output URI in each generated document
Input XML:
<?xml version="1.0" encoding="UTF-8"?>
<chapters>
<chapter id="ch1" title="Introduction"/>
<chapter id="ch2" title="Getting Started"/>
</chapters>
Stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/chapters">
<xsl:for-each select="chapter">
<xsl:result-document href="{@id}.xml">
<chapter id="{@id}"
self-uri="{current-output-uri()}">
<title><xsl:value-of select="@title"/></title>
</chapter>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Output (ch1.xml):
<chapter id="ch1" self-uri="ch1.xml">
<title>Introduction</title>
</chapter>
Log generated file names to the principal output
Stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"

<xsl:output method="xml" indent="yes"/>
<xsl:template match="/chapters">
<manifest>
<xsl:for-each select="chapter">
<xsl:result-document href="{@id}.xml">
<chapter/>
</xsl:result-document>
<file><xsl:value-of select="concat(@id, '.xml')"/></file>
</xsl:for-each>
</manifest>
</xsl:template>
</xsl:stylesheet>
Notes
- Returns the empty sequence when called in the principal result tree (outside any
xsl:result-document). - The returned URI is the value of the
hrefattribute of the enclosingxsl:result-document, resolved against the static base URI if it is relative. - Useful for generating self-referential metadata in split-document outputs.
