iphone - Parsing SOAP result using TouchXML in iOS SDK (iPad) -

i'm working on ipad project using functions in webservice. handling webservice connection, data etc works find. i'm not able parse result soap using touchxml. getting nodes out of xml returns 0 length.

the output xml:

<?xml version="1.0" encoding="utf-8"?> <soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" 
xmlns:xsd="http://www.w3.org/2001/xmlschema">

    <soap:body>
        <logonresponse xmlns="http://coreservices.org/v1">
            <logonresult>
                <id>1c0e9ad0-a3be-4cd0-8f0d-0616a63a4e28</id>
                <userid>2</userid>
                <user>
                    <id>2
                    <name>beheerder
                    <emailaddress />
                    <culturename>nl-nl</culturename>
                </user>
            </logonresult>
        </logonresponse>
    </soap:body>
</soap:envelope> 

parser code:

  nsdata *adata = [[nsdata alloc] initwithbytes:[webdata mutablebytes]
                                        length:[webdata length]];   nsstring *xmldata = [[nsstring alloc] initwithdata:adata 
                                           encoding:nsasciistringencoding];   nslog(@"%@", xmldata);   [xmldata release];   cxmldocument *domuseridentity = [[[cxmldocument alloc] initwithdata:adata 
                                                             options:0 
                                                               error:nil]
                                                                autorelease];  [adata release];   nsarray *nodeslist = [domuseridentity nodesforxpath:@"//logonresult" error:nil]; // 0 length      (cxmlelement *resultelement in nodeslist) {         (int counter = 0; counter              nsstring *elemname = [[resultelement childatindex:counter] name];             nsstring * elemvalue = [[[resultelement childatindex:counter]
                                                             stringvalue] 
                                        stringbytrimmingcharactersinset:
                        [nscharacterset whitespaceandnewlinecharacterset]];     [elemname release];    [elemvalue release];   } }   [nodeslist release]; 

any idea did wrong?
