Getting unwanted xmlns prefix in transformation output

[rvanderh]

I'm using oXygen XML editor 20.1. We're downloading XML records from a remote site and transforming to a different XML schema. The transformed records then need to be uploaded to a different website (crossref.org). My stylesheet needs to be adjusted so that the namespace elements are correct in the root element (doi_batch).

Here is a sample XML record that we're starting with:

Code: Select all

<OAI-PMH xmlns="http://www.openarchives.org/OAI/2.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.openarchives.org/OAI/2.0/ http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd">

     </xsl:element>

   </xsl:template>

</xsl:stylesheet>

The problem is that in the transformed output, the doi_batch element has "xmlns:record=" which instead should be just "xmlns=". I've tried several different ways to fix this but nothing is working correctly.

[Radu]

Hi,

That extra xmlns:record namespace mapping seems to be forcefully generated by you in the XSLT using:

Code: Select all

<xsl:namespace name="{local-name()}" select="'http://www.crossref.org/schema/4.4.1'"/>

on a template which matches an element called "record".

Regards,
Radu

[rvanderh]

Agreed. But name is a required attribute for the namespace element and I don't know how to adjust the value of name so that the prefix :record is omitted. If I adjust lines 11 and 18 in the stylesheet to "OAI-PMH/GetRecord" and then add /record to my value-of expressions in the rest of the stylesheet below, the xmlns prefix in the doi_batch element becomes :GetRecord in the output. I want to eliminate the prefix altogether but everything I've tried throws an error.

[rvanderh]

Also, if I delete the xsl:namespace line (line 20) in the stylesheet and instead add a namespace attribute to the doi_batch element above (line 19), the xmlns prefix disappears in the output but then I also get empty xmlns="" added to the head and body elements in the output.

[Radu]

Hi,

I think what you really need it to add an extra xmlns="http://www.crossref.org/schema/4.4.1" on the xsl:stylesheet root element so that all XML elements emitted by the XSLT are in that namespace. And remove that xsl:namespace element.

Radu

Thanks! That worked.
