unable to parse xml with javascript loadXMLString() - php

Question

I am trying to parse the xml file from a webservice. I am using javascript loadXMLString function to parse the xml into html. with local file it was working fine if i insert the xml code in to a variable. but for getting xml from external link i have used php function here like this:
<?php
$request = "http://www.somewebsite.com/feeds/get-cities.php?vendor_key=xxx";
$response = file_get_contents($request);
$xmlstring = htmlspecialchars($response, ENT_QUOTES);
?>
<script language="javascript">
function loadXMLString(txt)
{
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(txt,"text/xml");
}
else // Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.loadXML(txt);
}
return xmlDoc;
}//function loadXMLString ends
text = <?php $xmlstring;?>
xmlDoc=loadXMLString(text);
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("city");
for (i=0;i<x.length;i++)
{
document.write("<tr style='background:#dddddd;'><td>");
document.write(x[i].getElementsByTagName("name")[0].childNodes[0].nodeValue);
document.write("</td><td>");
document.write(x[i].getElementsByTagName("country")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");
</script>
in the above code i am trying to insert the xml code from a php variable $xmlstring to javascript variable text. but it display nothing. but if i put the xml code inside the script like below it works perfectly:
text="<cities>"
text=text+"<city>";
text=text+"<name>bulga</name>";
text=text+"<country>Giada De Laurentiis</country>";
text=text+"<city_id>2005</city_id>";
text=text+"</city>";
text=text+"</cities>";
does any body know how can i parse it. or if somebody have a better solution please suggest me that also.

Answer 1

Try to change following line in your code
text = <?php echo $xmlstring;?>
it should echo your variable value.

Answer 2

With the help of GBD i have written the following code and its start displaying the city list. but when i try this with different xml code it does not work. may be someone have better solution for this
<?php
function curl_get_file_contents($URL)
{
$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_URL, $URL);
$contents = curl_exec($c);
curl_close($c);
if ($contents) return $contents;
else return FALSE;
}
$xmlString = curl_get_file_contents("http://www.somesite.com/feeds/get-cities.php?vendor_key=xxx");
?>
<script language="javascript">
function loadXMLString(text)
{
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(text,"text/xml");
}
else // Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.loadXML(text);
}
return xmlDoc;
}
var text = "<?php echo substr_replace($xmlString,"",0,39);?>";
xmlDoc=loadXMLString(text);
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("city");
for (i=0;i<x.length;i++)
{
document.write("<tr style='background:#dddddd;'><td>");
document.write(x[i].getElementsByTagName("name")[0].childNodes[0].nodeValue);
document.write("</td><td>");
document.write(x[i].getElementsByTagName("country")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");
</script>
