I need in JavaScript to load in variable contents of another page from the same site and then get data from that contents (parse XML).
I have gotten in text string variable the page's HTML using XMLHttpRequest() and responseText property.
After that I converted text string into xml object (DOMParser) and tried to use XPath.
In FireFox's console I saw error:
Node cannot be used in a document other than the one in which it was created
How can I convert XMLHttpRequest() result into document object to process it using XPath? How I should use document.evaluate with this object? Is there the easier way to do my task?
textString=file_get_contents('my url');
var parser = new DOMParser();
xml = parser.parseFromString( textString, "text/xml" );
list = getI( "(//td[contains(text(), 'Total:')])[1]",xml);
// Error: Node cannot be used in a document other than the one in which it was created`enter code here`
// HOW USE getI function here? (document.evaluate)
function file_get_contents( url ) { // Reads entire file into a string
//

// % note 1: This function uses XmlHttpRequest and cannot retrieve resource from different domain.
var req = null;
try { req = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) {
try { req = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {
try { req = new XMLHttpRequest(); } catch(e) {}
}
}
if (req == null) throw new Error('XMLHttpRequest not supported');
req.open("GET", url, false);
req.send();
return req.responseText;
}
function getI(xpath,elem){return document.evaluate(xpath,(!elem?document:elem),null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);}
