[sarissa] XPath

11-03-2005

Hello,

I found the following XHTML document for testing sarissa's XPath
implementation at http://sarissa.sourceforge.net/doc/. I replaced
"Sarissa_0-9b3.js" in the test document below by "sarissa.js" from
sarissa0.9.6.1. Loading the document Firefox replies "XML filtering
predicate operator called on incompatible XMLDocument". What's wrong?

Thanks in advance,
Christoph

Firefox replies? Does that mean you get that message as an error message
in the JavaScript console?
Then there usually is the line number and URL of the HTML or JavaScript
document the error occurs in?
So those details should be provided if you want help.
And it might make more sense to ask in the Sarissa specific place like
<https://sourceforge.net/forum/forum.php?forum_id=256492>
Looks that recently someone else there already had problems with that
example.

Thanks, the answer from the sarissa group is the following.

Regards,
Christoph

The extra thing I needed was just an include for the
sarissa_ieemu_xpath.js script.

I definitely also needed:
xmlDoc = parser.parseFromString( xmlStr, "text/xml" );
instead of:
xmlDoc.(new DOMParser()).parseFromString(xmlStr, "text/xml");

And the line:
var xmlDoc = Sarissa.getDomDocument();

is not necessary at all.
However, the xmlDoc.setProperty's do work now.

Can the example be fixed?
