xml - Issue with XmlNode.SelectNodes -


i'm getting web service below xml , i'm try select ttcontext nodes need parse contextvalue node contextgroup = pcsessionid.

i figured first make sure @ ttcontext nodes , work there modify code go when run below code node list contains 0 nodes. can lead me in right direction?

dim xmldoc xmldocument = new xmldocument

xmldoc.loadxml(e.innerxml)

e.innerxml contains below xml:

   <soap-env:envelope          xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"          xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"          xmlns:xsd="http://www.w3.org/2001/xmlschema">         <soap-env:body>            <apsrvresponse xmlns="urn:etimews:etimews">               <result xsi:nil="true" />               <dscontext>                  <ttcontext>                     <contextgroup>param</contextgroup>                     <contextname>pcpassword</contextname>                     <contextvalue>admin</contextvalue>                     <contextoperator />                     <contexttype />                  </ttcontext>                  <ttcontext>                     <contextgroup>param</contextgroup>                     <contextname>pcsessionid</contextname>                     <contextvalue>admin.8c4a11bf-a8e0-3e9e-df11-84e3cd76215d.bjzfvubladuixkmj</contextvalue>                     <contextoperator />                     <contexttype />                  </ttcontext>                  <ttcontext>                     <contextgroup>param</contextgroup>                     <contextname>pcuserid</contextname>                     <contextvalue>admin</contextvalue>                     <contextoperator />                     <contexttype />                  </ttcontext>               </dscontext>            </apsrvresponse>         </soap-env:body>      </soap-env:envelope>

dim root xmlnode = xmldoc.documentelement dim nodelist xmlnodelist = root.selectnodes("/dscontext/ttcontext")

a little complicated namespaces. used xml linq

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
