xml parse with php... am i missing something? please help

The code below is suppose to output a list of neighborhoods for a given city. Right now it's taking the first neighborhood and repeating (what seems to be) infinitely (ex. eastside eastside eastside eastside.......). I need it to pull all neighborhoods (ex. eastside, westside, downtown, south hill.......). Any help is appreciated

<?php


function marketwatch($city1, $state1)
{
    // Setup query string parameters 
    $apikey = 'MyKey';
    $request = 'http://api.trulia.com/webservices.php?library=LocationInfo';
    $request .= '&function=getNeighborhoodsInCity&city='.urlencode ($city1);
    $request .= '&state='.$state1;
    $request .= '&apikey='.$apikey;
    
    // Make the request
    $response = file_get_contents($request);

    // Retrieve HTTP status code
    list($version,$status_code,$msg) = explode(' ',$http_response_header[0], 3);

    // Check the HTTP Status code
    if($status_code != 200) 
    {
        die('Your call to Trulia Web Services failed: HTTP status of:' . $status_code);
    }

    // Create a new DOM object
    $dom = new DOMDocument('1.0', 'UTF-8');

    // Load the XML into the DOM
    if ($dom->loadXML($response) === false) 
    {
        die('XML Parsing failed');
    }

    // Get the first searchResultsURL XML node
    $searchResultsURL = $dom->getElementsByTagName('searchResultsURL')->item(0);


    // Write out our table header w/ the City / State the data is for
    echo '<table width="100%" cellspacing="0">';
    echo '<tr><td><b>Neighborhoods ';
    echo '<a href="'.$searchResultsURL->nodeValue.'">'.$city1.', '.$state1.'</a>';
    echo '</b></td></tr>';
    echo '<tr><td class="center"><br>';
    echo '</td><td class="center">';
    echo '</td><td class="center"><br>';
    echo '</td></td>';

    // Get the first listingStat XML node
    $neighborhood = $dom->getElementsByTagName('neighborhood')->item(0);


    // Write out our table rows w/ data
    while($neighborhood) 
    {
        $i++;
        $neigh =  $neighborhood->getElementsByTagName('name')->item(0);
        if (($i % 2) == 1) 
        {
            echo '<tr bgcolor="#FAF6E4"><td class="center">';
        }
        else
        {
            echo '<tr><td class="center">';
        }

        print_r($neigh->nodeValue);
        echo '</td></tr>';

        $neigh = $neigh->nextSibling;
    }

    // Finish off our table w/ Trulia attribution
    echo '</table><br>';
    echo '<a href="http://www.trulia.com" target="_top" title="Trulia Real Estate Search">';
    echo '<img src= "http://images.trulia.com/images/logos/trulia_logo_70x42.jpg" alt="Search Real Estate and Homes for Sale" border="0" />';
    echo '</a>';
}

<?php
marketwatch('Seattle', 'WA');

Well because its repeating the words over and over agian somthing in that while loop is prime candidate...

...the line:

$neigh = $neigh->nextSibling;

I think it should be:

$neigh = $neigh->next_sibling;

more info: http://uk2.php.net/manual/en/function.domnode-next-sibling.php

 

that didn't work... but I was thinking along the same lines as that.

for that part, below is an excerpt of something I have working correctly parsing a different xml. If you can see where the ->firstChild line is I took that out above code because there is no child element for 'neighborhood'.

    // Get the first listingStat XML node
    $listingStats = $dom->getElementsByTagName('listingStats')->item(0);
    $listingStat = $listingStats->firstChild;

    // Write out our table rows w/ data
    while($listingStat) 
    {
        $i++;
        $weekEndingDate =  $listingStat->getElementsByTagName('weekEndingDate')->item(0);
        $subcategory = $listingStat->getElementsByTagName('subcategory')->item(0);
        $medianListingPrice = $subcategory->getElementsByTagName('medianListingPrice')->item(0);
        $numberOfProperties =  $subcategory->getElementsByTagName('numberOfProperties')->item(0);
        if (($i % 2) == 1) 
        {
            echo '<tr bgcolor="#FAF6E4"><td class="center">';
        }
        else
        {
            echo '<tr><td class="center">';
        }

        print_r($weekEndingDate->nodeValue);
        echo '</td><td class="center">';
        print_r(number_format($numberOfProperties->nodeValue));
        echo '</td><td class="center">$';
        print_r(number_format($medianListingPrice->nodeValue));
        echo '</td></tr>';

        $listingStat = $listingStat->nextSibling;
    }
