exclude-result-prefixes

Hi guys,

I am having an issue with the exclude-result-prefixes functionality it xslt.

I am including an fpml library in my code.. but every fpml elelemnt comes with the

web site after it.

ie

Code:



<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:fpml="http://www.fpml.org/2008/FpML-4-5"
    exclude-result-prefixes="fpml" >

But I am still getting the following

- <fpml:trade xmlns:fpml="http:=//www.fpml.org/2008/FpML-4-5">

when what i really want is

- <fpml:trade>

Code:

<xsl:element name ="fpml:trade">

I have added the exclude_result_prefix.. but it just will not go away......
Can I have some advice please

thanks

exclude-result-prefixes only excludes unused prefixes, and will not exclude a used prefix as that would result in an invalid XML document.

Try including the namespace declaration on the root output object, and then it might not get included in child elements, so you will only see it once, which certainly looks cleaner.

Without seeing more of your input or output it is hard to give more advise.

The document

<fpml:trade/>

without a namespace declaration would be ill-formed (according to the XML Namespaces specification), and XSLT is designed to make it impossible to produce ill-formed output. So there's no way to do this - and no reason to want to.

The attribute exclude-result-prefixes can be used to eliminate unused namespace declarations from your output, but it can't be used to eliminate declarations that are necessary for the document's integrity.
