Retrieving XML attributes with XMLXPATH in v28

[Chris Wilcock]

Hello

I have an XML file with the following structure

<Connect version='1.0'>
    <!-- ... -->
</Connect>

Prior to v28, I was using the following to retrieve the value of the 'version' attribute:

ECHO %@XMLXPATH["test.xml",/Connect/@version]

However, in v28 TCC is returning an error:

TCC:  "/Connect/@version"

I can work around this using a combination of XMLOPEN, XMLXPATH and XMLGETATTR, but is this a known issue in v28 or do I need to change the syntax of the original statement?

Thanks for your help!

Chris

It also fails in v27 (and works in v26). This (below) works in v28. I don't know enough about XML to say why it works or if there's some general principle at play here.

v:\> type xml.xml
<Connect version='1.0'>
    <!-- ... -->
</Connect>

v:\> ECHO %@XMLGETATTR["xml.xml",version]
1.0

Hello Vince!

Thanks very much for this, I can use this as a workaround as there is only one 'version' attribute in the XML document that I'm parsing. I suspect that the reason this is working is because the @XMLGETATTR function is operating on the root node by default when the filename is passed as an argument. I moved the attribute to a child node out of curiosity and it failed to find the attribute any more.

This is a good workaround though, so thank you again!
