getting node path
Locked
 
|
just wondering - is there an xpath function that will return a path? I looked for something like this and don't understand why it doesn't seem to exist. It would greatly simply an application of mine if I could just store the path to a specified node to an instance. Something like returnPath(node) as xs:string ? If not, is there a specific reason it can't be implemented?

Hi Francis,
There is a Saxon extension that does what you're describing here: saxon:path(). See: http://www.saxonica.com/documentation/extensions/functions/path.html Since Orbeon Forms uses Saxon to run XPath expressions in XForms, you can use it wherever you can write an XPath expression in XForms. You should be aware though that this has limitations: it works well in simple cases, but an XPath expression is not like a pointer; for instance, if your document changes, depending on the cases it might point to a different node.

Alex- That's exactly what I was looking for, thanks very much!
I don't think there will be a problem with the document changing. I'd just be using this for an RTE dialog where the string would be used with the evaluate() function to update the node that "called" it. (The dialog is modal, so I don't think the user could change the document in the time that this string exists). This eliminates a lot of somewhat clumsy code I was using to "reconstruct" the path.

Paul,
Don't worry about it; it happened to all of us, at one time or another :). Your messages didn't make it to the mailing list, but were shown on Nabble, which apparently doesn't know how to filter on that type of messages.
