    copied!<p>I can't seem to parse my xml today. What have I done wrong? I'm hoping someone can point me to a better/working solution.</p> <p>I want to parse a bus route xml file that looks like this:</p> <pre><code>&lt;buses&gt; &lt;bus&gt; &lt;num&gt;12&lt;/num&gt; &lt;stime&gt;05:00&lt;/stime&gt; &lt;etime&gt;22:00&lt;/etime&gt; &lt;freq&gt;?&lt;/freq&gt; &lt;route&gt; &lt;stop&gt;Eonyang Bus Terminal&lt;/stop&gt; &lt;stop&gt;Chuk Hyub&lt;/stop&gt; &lt;stop&gt;Eonyang Bolim Hospital&lt;/stop&gt; &lt;stop&gt;Samnammyeong Residential Center&lt;/stop&gt; &lt;stop&gt;SinAn&lt;/stop&gt; &lt;/route&gt; &lt;/bus&gt; &lt;bus&gt; &lt;num&gt;13&lt;/num&gt; &lt;stime&gt;?&lt;/stime&gt; &lt;etime&gt;?&lt;/etime&gt; &lt;freq&gt;?&lt;/freq&gt; &lt;route&gt; &lt;stop&gt;KTX Ulsan Station&lt;/stop&gt; &lt;stop&gt;Driving Hagwon&lt;/stop&gt; &lt;stop&gt;Jayeon Science High School&lt;/stop&gt; &lt;stop&gt;Eonyang Bus Stop&lt;/stop&gt; &lt;stop&gt;Bolim Hospital&lt;/stop&gt; &lt;stop&gt;Daewon Green Apt.&lt;/stop&gt; &lt;/route&gt; </code></pre> <p> </p> <p>Based on user input of origin and destination, I want to search through the list of stops to find the desired bus or buses, but simply parsing this list is not working. </p> <pre><code>&lt;?php $xmlDoc = new DOMDocument(); $xmlDoc-&gt;load("buses-new.xml"); $buses=$xmlDoc-&gt;getElementsByTagName('bus'); for($i=0; $i&lt;($buses-&gt;length); $i++) { $route=$buses-&gt;item($i)-&gt;getElementsByTagName('route'); $busnum=$buses-&gt;item($i)-&gt;getElementsByTagName('num'); foreach( $route-&gt;childNodes as $stop) { $loc = $stop-&gt;nodeValue; if (stristr($loc,$orig)) { // found a bus with origin $origins[$ocount]= $i; $ocount++; } if (stristr($loc,$dest)) { // found a bus with destination $destination[$dcount] = $i; $dcount++; } } // for all stops } // for all buses </code></pre> <p>I'm getting an error on ---- foreach( $route->childNodes as $stop) -- says in invalid argument.</p> <p>what is the right way to parse an indeterminate list of childnodes from each route?</p>
