Replacing a Namespace with XSLT
- by er4z0r
Hi I want to work around a 'bug' in certain RSS-feeds, which use an incorrect namespace for the mediaRSS module. I tried to do it by manipulating the DOM programmatically, but using XSLT seems more flexible to me.
Example:
<media:thumbnail xmlns:media="http://search.yahoo.com/mrss" url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" />
<media:thumbnail url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" />
Where the namespace must be http://search.yahoo.com/mrss/ (mind the slash).
This is my stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="//*[namespace-uri()='http://search.yahoo.com/mrss']">
<xsl:element name="{local-name()}" namespace="http://search.yahoo.com/mrss/" >
<xsl:apply-templates select="@*|*|text()" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Unfortunately the result of the transformation is an invalid XML and my RSS-Parser (ROME Library) does not parse the feed anymore:
java.lang.IllegalStateException: Root element not set
at org.jdom.Document.getRootElement(Document.java:218)

... 8 more
What is wrong with my stylesheet?
