Help with some XPATH questions

2005-07-28 14:06:53
from [Vincenzo Menanno] [Permanent Link] 
Hi there I need some real guru help here... 

I am a real novice here on this stuff... so be kind :)

I have an XML document that has a structure something like this... but inside 
the Layout elements there can be many other descendants called objects... some 
objects can be not directly under Layout but nested way beneath inside other 
elements... 

<FMPReport>
    <File>
        <LayoutCatalog>
            <Layout>
                <Object>
            <Layout>
        <LayoutCatalog>
    </File>
</FMPReport>

I want to be able to pull out individual items...

So for example I want to pull out all the Objects that have type elements with 
an attribute of 'Text' --- then I want to have another template process all the 
type elments with an attribute of 'Field' etc... etc... 


So far what I have is 

            <RESULTSET>
                <xsl:attribute name="FOUND">
                    <xsl:value-of select="count(//LayoutCatalog/Layout)"/>
                </xsl:attribute>
                <xsl:apply-templates 
select="//LayoutCatalog/Layout/descendant::Object[(_at_)type='text']"/>
            </RESULTSET>


I thought that this would work but it does not... this is the error I get:

Description: E Error in expression 
//LayoutCatalog/Layout/descendant::Object[(_at_)type='text']: Axis in pattern 
must be child or attribute

I guess what I don't understand this error - and I also don't really understand 
the role of

"<xsl:attribute name="FOUND">"

Then the "xsl:apply-templates select" that follows - I am under the impression 
that it just is something that follows, extends the found set in some way... 

Any help or advice would greatly be appreciated... Thanks

Vince

Below is a layout with possible text objects on there.
