How To remove empty space in xml.@Adrian Pirvulescu

Answer 1

Yes it is possible.

Considering your xml is declared like this

var myXML:XML = new XML(<item label="">R1</item>);

You can do the following:

myXML.setChildren("");
trace(myXML.toXMLString());

-- Output: <item label=""></item>

UPDATE

Since you updated your example I need to update my post as well. Since you want to remove only in nodes where @label is "" then you can use the following.

resultXML..item(@label == "").setChildren("");

Answer 2

Why you need Empty node? But still if you want it do like so,

Assuming your xml has only one node,

var xml:XML = <item label="">R1</item>
xml.replace(0, <item></item>);
