hi all,
I'm having trouble with DTM node handles. I have two Document structures
-- A and B -- on which I am computing a union. I am implementing the
union by importing nodes from B into A, via Document#importNode. The
trouble is that I am getting the following exception when executing an
XPath on the resulting structure -- thrown when 'contextNode' in the
code snippet below is an imported node:
java.lang.RuntimeException: Could not resolve the node to a handle
at
org.apache.xml.dtm.ref.DTMManagerDefault.getDTMHandleFromNode(DTMManagerDefault.java:625)
at
org.apache.xpath.XPathContext.getDTMHandleFromNode(XPathContext.java:220)
...
The code I'm using the execute a (pre-compiled) XPath is:
xpath.execute(
xpathSupport, xpathSupport.getDTMHandleFromNode( contextNode
), prefixResolver
);
where 'prefixResolver' and 'xpathSupport' are cached objects. I
basically have something like CachedXPathAPI set up, except the XPath
objects are pre-compiled.
I'm new to this package, and I have a feeling I'm doing something
fundamentally wrong. I'd assume that the #importNode method would take
care of the details, but maybe that doesn't even make sense ...
Is there a standard way to clean up the DTM after modifying a structure?
In the archive I've seen references to "use a new DOMSource", but from
the APIs I can't make sense of the specifics. I'm guessing that's
equivalent to re-loading the entire structure...
[0] seems to be similar, but I don't know if it's related.
Any help would be greatly appreciated,
Brien
