Re: How to get rid of namespace? (Xindice 1.1b2)

[Terry Rosenbaum]

The behavior you see is a bug.

See: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13746

You can build a version without this bug through a quick hack
to  org.apache.xindice.xml.dom.DocumentImpl. Comment
out these 2 lines:

importNamespaces(importedNode, clone);

and

importNamespaces(importedNode, result);

and rebuild.

I have not submitted this as a patch since it is not
a complete solution. It only solves the problem
for a limited set of uses cases (e.g. complete
solution if not using namespaces, and likely a
solution for many cases where you use namespaces,
but may not be correct for all uses of namespaces).
See the bug for a more complete explaination.

This hack will leave the src:key attribute, for example, intact and correct.

I managed to get rid of those "xmlns:src" attributes by modifying the method "expandSource" of class

org.apache.xindice.xml.dom.ElementImpl.java by removing the body as in:

 

    public void expandSource() {

    }

 

Then I re-built Xindice.

 

Now the result from the database is clean, but the root element of each document contained in the result set no longer has the "src:key" attribute:

 

 

                ...
                <elem1 id="k2">
                        <type>AK</type>
                        <elem2>
                                <elem3 id="c">
                                        <elem4>A</elem4>
                                </elem3>
                                <elem3 id="b">
                                        <elem4>D</elem4>
                                </elem3>
                        </elem2>
                </elem1>
                ...

 

It's easy to see this is not the right solution... Under certain circumstances the "src:key" attribute is relevant.

 

How can I get rid of the "xmlns:src" in all non-root elements of documents in a result set from a Xindice 1.1b2 server

(but, again, keeping them in the root elements)?

 

Thanks,

Subject: How to get rid of namespace? (Xindice 1.1b2)

I was able to run a query against a collection using the CollectionImpl class.

 

I get each and every element in the result set tagged with a namespace, like:

 

                ...
                <elem1 id="k2" xmlns:src=""http://xml.apache.org/xindice/Query">http://xml.apache.org/xindice/Query">
                        <type xmlns:src=""http://xml.apache.org/xindice/Query%22%3EAK%3C/type">http://xml.apache.org/xindice/Query">AK</type>
                        <elem2 xmlns:src=""http://xml.apache.org/xindice/Query">http://xml.apache.org/xindice/Query">
                                <elem3 id="c" xmlns:src=""http://xml.apache.org/xindice/Query">http://xml.apache.org/xindice/Query">
                                        <elem4 xmlns:src=""http://xml.apache.org/xindice/Query%22%3EA%3C/elem4">http://xml.apache.org/xindice/Query">A</elem4>
                                </elem3>
                                <elem3 id="b" xmlns:src=""http://xml.apache.org/xindice/Query">http://xml.apache.org/xindice/Query">
                                        <elem4 xmlns:src=""http://xml.apache.org/xindice/Query%22%3ED%3C/elem4">http://xml.apache.org/xindice/Query">D</elem4>
                                </elem3>
                        </elem2>
                </elem1>
                ...

 

I actually made another version of CollectionImpl.query(), which returns the content from the server without building a resource set as in:

 

 

    public String queryAsString(String name, String queryLang, String query, Hashtable nsMap) throws XMLDBException {

 

        checkOpen();
        try {

 

            Hashtable params = new Hashtable();
            params.put(RPCDefaultMessage.COLLECTION, collPath);
            params.put(RPCDefaultMessage.TYPE, queryLang);
            params.put(RPCDefaultMessage.NAMESPACES, nsMap);
            params.put(RPCDefaultMessage.QUERY, query);

 

            if (name != null) {

 

                params.put(RPCDefaultMessage.NAME, name);
            }

 

            String result = (String) runRemoteCommand("Query", params);
           
            return result;
        } catch (Exception e) {

 

            throw FaultCodes.createXMLDBException(FaultCodes.QRY_PROCESSING_ERROR, "Query error", e);
        }
    }

I then invoke it like:

 

 String rs=null;
 try {
  rs = coll.queryAsString(null,"XPath","/entity",new Hashtable());
  System.out.println("RESULT===>>> " + rs);

 }
 catch (XMLDBException e) {
  System.out.println("XMLRPCTest.main(): query() failed: " + e.getMessage());
  e.printStackTrace();
 }

Any ideas?

 

Thanks,
