This won't solve your problem necessarily, but you should use the responseXML property instead of parsing the responseText property with DOMParser().

I am having some trouble using element.evaluate(properties) with documents fetched with XMLHttpRequest, so I am looking for a method to do the same as this: //***** var roundinfo = { runde : "56", heroesid : null, heroesnick : null } var path = '//table/tbody/tr/td'; var obj = document.evaluate(path,document,null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); for (var k = 0; k < obj.snapshotLength; k++) { obj2 = obj.snapshotItem(k).parentNode; var nodes = obj2.childNodes; dump("Found keys: "+nodes.length+"\n"); var menu = nodes[0].textContent.trim().split("#"); roundinfo.heroesnick = menu[0].trim(); roundinfo.heroesid = menu[1].trim(); dump("Nick is: "+roundinfo.heroesnick+"\n"); dump("ID is: "+roundinfo.heroesid+"\n\n"); } //***** And the document contains this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title></title> </head> <body> <table> <tr> <td colspan="3"><font face="arial" size="1" color="DarkTurquoise">Axe Decapitators #130303</font></td> </tr> </table> </body> </html> And the dump would be Nick is: Axe Decapitators ID is: 130303 And I tried some things to make it with XMLHttpRequest: //******* Attemp: var req = new XMLHttpRequest(); req.overrideMimeType('text/html'); req.open('GET', 'http://www.URL_TO_FETCH_CONTAINING_THE_ABOVE_CODE.dk', true); req.onreadystatechange = function () { if (req.readyState == 4) { if(req.status != 404) { var path = '//table/tbody/tr/td/font'; var domParser = new DOMParser(); var dom = domParser.parseFromString(req.responseText, "text/xml").documentElement; var obj = dom.evaluate(path,dom,null,XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); for (var k = 0; k < obj.snapshotLength; k++) { obj2 = obj.snapshotItem(k).parentNode; var nodes = obj2.childNodes; dump("Found keys: "+nodes.length+"\n"); var menu = nodes[0].textContent.trim().split("#"); roundinfo.heroesnick = menu[0].trim(); roundinfo.heroesid = menu[1].trim(); dump("Nick is: "+roundinfo.heroesnick+"\n"); dump("ID is: "+roundinfo.heroesid+"\n\n"); } } else dump("Error loading page with status"+ reg.status +"\n"); } }; req.send(null); But this only results in this: Error: syntax error Source File: chrome://browser/content/browser.xul Line: 1, Column: 62 Source Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">-------------------------------------------------------------^ Any tips on how to do this "right"?
