Filtering (using XML) does not work in Firefox and Chrome?

I’ve loaded this file as a sample, but filtering from XML does not work in Firefox AND Chrome:
/dhtmlxCombo/dhtmlxCombo/samples/04_filtering/02_combo_filter.html

It works fine in IE, though.

The same is true when I implement the solution in my own environment.

I’ve used this function to enable filtering (my XML is dynamically generated):

var z=new dhtmlXCombo(“combo_zone2”,“alfa2”,200);
z.enableFilteringMode(true);
z.loadXML(“MyXml.xml”);

Also, I’ve noticed that Filtering actually DOES start to work fine in CHROME and FF, when I reference the XML in this format:
z.loadXML(“https://dmtool-int20.eumetsat.int/cs/EumUIComponent/docAuthors_lookup_new.xml”);

It DOES NOT work when I reference the same XML in this format:
z.loadXML(“https://dmtool-int20.eumetsat.int/cs/idcplg?IdcService=EUM_COMBO_GET_SCHEMA_VIEW_VALUES&schViewName=docAuthors_lookup”);

Note that the end result when you call both XML links is the same.

This was a problem with our XML. After I’ve removed white spaces from XML, filtering in both FF and Chrome is working.
