Fundamental namespace problem?

danielh · January 3rd, 2008, 06:02 PM

In the .xml file, I declare:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="CatalogItem.xsl"?>
<catalogItem xmlns="http://www.fineHomemadeSoap.com/Catalog"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.fineHomemadeSoap.com/Catalog
        CatalogItem.xsd"
    >
    <sortProperty>Lavender</sortProperty>
...

When I do this, the CatalogItem.xsl file is not applied, and the .xml file's text is displayed in the browser, with all the tags stripped-out.

If I change the heading as follows, everything works properly:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="CatalogItem.xsl"?>
<catalogItem
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.fineHomemadeSoap.com/Catalog
        CatalogItem.xsd"
    >
    <sortProperty>Lavender</sortProperty>
...

Please read the first "sticky" post in this forum, or google for "XSLT default namespace".

Michael Kay,
I have your book, "XSLT 2.0," 3rd Ed. I bought it to supplement my XML course. I also have "Beginning XML," 3rd, whereas I don't see your name on the authors. Your book helps tremendously. When I took the class, I got more out of your book (for one lesson) than the required textbook.

I understand the message of your post is to perform adequate research in advance before making a post. However, I assure you that I have many hours in this topic. I am on vacation, and for 4 days, this has been a major project. That's probably 30-40 hours. I wouldn't make this post if I didn't have a large amount of advance work involved.

There is something in the dynamics of transforming one .xml file into another, if a default namespace is named in the original document, and I don't understand why.

For 4 days, this has been bugging me. I don't like to make changes in a document without understanding.

Please don't get me wrong. I am very grateful for responses, and I would even be grateful for a reference to go read.

Interestingly, in your book, p.66, I see a default namespace is not defined in the source document.

Mr. Kay,
Thank you very much for the reference.
My browser only honors XSLT 1.0, so I do not have xpath-default-namespace.

As an amend, I tried to figure out how to refer to a specific namespace node using xpath (an experiment all the way):

<xsl:value-of select="catalogItem/test"/>
or: <xsl:value-of select="cat:catalogItem/test"/> (ambiguous-should be an error)

, but I think it'll work if I have a null default namespace in the .xml source document.

I'll continue to investigate the XPath naming rules, in case I'm missing something.
