Issues with IE11 not displaying maps WordPress

  • SOLVED

Please check https://www.mapsmarker.com/dev/pro/ - in contrast to other browsers not all but only the first two maps are displayed. IE11 shows a syntax error in the console for

return(new window.DOMParser).parseFromString(a,"text/xml");

The unshrinked javascript-code for GPX tracks can be found here: https://www.mapsmarker.com/dev/gpx-uncompressed.js

If you display the posts separately, all maps work. Just dont get it - any help is appreciated!
thx!

The XML that's being parsed doesn't validate. That might well be your problem.

Interestingly, Chrome is happy to parse it, whereas IE11 isn't.

Here's the XML:

Checked with http://validator.w3.org/check

Robert Seyfriedsberger comments:

you´re right, thanks. Removed the (non existing) gpx url and then it works - seems like I have to add a fallback for IE if gpx cant be parsed (any hints appreciated ;-)

John Cotton comments:

...mind you, I've cleaned up the XML and got it to validate and IE still gives an error!

Robert Seyfriedsberger comments:

FYI: the url to the gpx file does not exist anymore and so the whole website gets loaded instead - this crashes IE maps. I removed the (non-existing) gpx url from map ID 335 and it worked again

Robert Seyfriedsberger comments:

the fallback would need to be added somewhere here I guess:

_parse_xml: function(xmlStr){
if (typeof window.DOMParser != "undefined") {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
} else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM")) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
} else {
throw new Error("No XML parser found");
}
},
