I have a php script that takes in some XML data and parses it, displaying various bits of information I pull out of it. This has been working fine for over 6 months, until recently it now fails mysteriously on a certain tag.

The XML is generated from an outside source(a conferencing bridge), so I have no control over how it is built. I have put the xml through an online validator and it returned no errors. The code also works fine when I connect to another conferencing bridge and get the same output.

I have been using XMLReader class so far and tried switching to SmipleXML, but it fails when I create the SimpleXML object using the data.

Here is the snippet of where it fails while parsing:

<CDR_SUMMARY> <FILE_VERSION>1001</FILE_VERSION> <NAME>Conference Title Hidden</NAME> <ID>10227</ID> <STATUS_STR>Auto_termination,_everybody_quit</STATUS_STR> <STATUS>4</STATUS> <GMT_OFFSET>-4</GMT_OFFSET> <START_TIME>2010-04-14T15:00:33</START_TIME> <DURATION> <HOUR>0</HOUR> <MINUTE>39</MINUTE> <SECOND>37</SECOND> </DURATION> <RESERVE_START_TIME>2010-04-14T15:00:33</RESERVE_START_TIME> <RESERVE_DURATION> <HOUR>12</HOUR> <MINUTE>0</MINUTE> <SECOND>0</SECOND> </RESERVE_DURATION> <MCU_FILE_NAME>c11</MCU_FILE_NAME> <FILE_SAVED>0</FILE_SAVED> <GMT_OFFSET_MINUTE>0</GMT_OFFSET_MINUTE> </CDR_SUMMARY>

The <SOUND> opening tag is the last one read before failing.

And this is my code: `public function processResponse($xml) { print "Processing List...";

    $reader = new XMLReader($xml);

    try {
        $reader->setSchema("./schemas/response_trans_cdr_list.xsd");
    } catch(Exception $e) {
        print "Exception:".$e->getMessage();
    }

    //verify xml
    if($reader->xml($xml)) {

            while($reader->read()) {
                //$currentstring = $reader->readstring();

            if($reader->name === "ACTION") {
                //into meat of resposnse
                while($reader->read()) {
                    //print "Looping...";
                    //$currentstring = $reader->readInnerXML();
                    //print $currentstring;
                    if($reader->nodeType == XMLReader::ELEMENT) {
                        if($reader->name === "ID") {
                            $this->conferenceIDs[$this->counter] = $reader->readString();
                            print "<BR>Conf ID found: ".$this->counter." ID: ".$this->conferenceIDs[$this->counter];
                            $this->counter += 1;
                        }
                        else if($reader->name === "START_TIME") {
                            //conference start time.

                        } else if($reader->name === "SECOND") {
                            print "<BR> SECOND Found!";

                        }
                    }else if($reader->nodeType == XMLReader::END_ELEMENT) {
                        print "Close Element".$reader->name;
                    }

                }
                print "End Action Loop";
            }
        }
    }
    else {
        print "Error reading response: Bad XML returned";
    }
}`

Anyone have any ideas what could be causing this failure? the code exits gracefully and I see the "End Action Loop" message in my output. It's like it just spontaneously exits the loop.
