XML Parsing is excruciatingly slow

[GoogleCodeExporter]

When processing an XML response of ~2.3 MB it takes > 10 minutes to parse the 
response.  Also the format of the output is difficult to search.  The new 
version treats every element as a collapsible section with the start tag on one 
line, the contents on the next line and the closing tag on the next line.

Neither of these were issues with the old app.

Currently whole parsing (either XML or JSON) is moved to background workers so 
it should go fast. However, I think think that when you collapse one element it 
collapses all collapsible elements inside which may causes delays. I'll check 
this.

Perhaps I am misunderstanding what you are saying, but when the XML is 
eventually displayed, all nodes are expanded.  On a side note, I can switch to 
raw output and see it instantly, but having collapsible nodes is very nice.

To clarify the formatting thing, I much preferred the way it used to work where 
only nested sections were collapsible.  Having the leaf nodes expandable and 
collapsible kinda just gets in the way.

For my own curiosity, what XML parser are you using?

Thanks for looking into this.

OK, I think I got it and I think you right.
I use XML for js library 
(http://xmljs.sourceforge.net/website/documentation-w3cdom.html) to parse XML 
string and then own highlight parser.
It is that way because XML parsing and highlighting is moved to background 
thread (Web Worker) and there is not such property a "document" which I can use 
to use code highlighter. So I need to use additional parser for XML files.
