When I translate and XML file that defines namespaces, I get the namespaces showing up in HTML tags. ? ?
I'm using Saxon 8B and Oxygen 7.0
I've created a small XML and XSLT file to show the problem:
XML File:
<?xml version="1.0" encoding="UTF-8"?><?mso-application progid="Excel.Sheet"?>
<Workbook
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Cell>Inside the Cell 1</Cell>
<Cell>Inside the Cell 2</Cell>
</Workbook>
The XSLT File:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<!--
****************************************************
-->
<!-- Begin Output Processing -->
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/Workbook">
<xsl:text>Found Workbook</xsl:text>
<xsl:apply-templates select="Cell"></xsl:apply-templates>
</xsl:template>
<!--
****************************************************
Template for Cell
****************************************************
-->
<xsl:template match="Cell">
<br/><xsl:text>Inside the Cell</xsl:text>
</xsl:template>
</xsl:stylesheet>
And finally the output:
<?xml version="1.0" encoding="UTF-8"?>Found Workbook<br xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>Inside the Cell<br xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>Inside the Cell
Notice the translated <br/> tags.. they have the xsi namespace declaration appearing inside the tags.
What's up with that?

OK, got the answer, never mind
needed 'exclude-result-prefixes'

You're not using the xsi namespace in your stylesheet, so why declare it?
If you do need to declare a namespace in your stylesheet that you don't want copied into the result tree, use exclude-result-prefixes to suppress it.

This is (obviously) the first time I've needed to deal with namespaces in the XML document I'm translating.
The document I'm using comes from Excel 2003 and defines 5 or 6 namespaces and they are all used in the complete document.
My example above was a paired back example in an attempt to show my problem.
I'm sure I'm asking a loaded question, I have read the 1.0 version of your book, but I don't see the reason why these
namespaces show up in such a (seemingly) bizarre place as the end of html tags.
Anyway
exclude-result-prefixes works so I'm back to work translating my documents.
Thanks for responding and thanks for the great book!

There's a rule in XSLT that when you write a literal result element in the stylesheet, it gets copied to the result document along with all its in-scope namespaces other than any excluded namespaces. The main reason for this is that the system can't tell which of the namespaces are needed and which aren't, so it's safer to copy them all.
