Firstly please check url*http://mobileecommerce.site247365.com/admin/catdata.xml in* google chrome. I am facing two problems 1. For second cat_desc from xml having cat_name E n I Sept not showing on webview .I think it is because in its cat_desc contains % sign on first line in table style tag <“table style=”border-collapse:collapse;width :100%;”>How to ignore % sign?
2.Second problem is that, from last thrid tag with cat_name Handouts creating problem while parsing it cat_desc.It will not parse completely, its last three lines are not parsed .I will check it in log also,but last three lines are not paresd.Why is it so ?For other cat_desc are parsed very well and well working on webview.

I have gone this URl:-
and find out that you have to make very small changes that use px instead of %.. as webview nor support %age symbol..
Hope it helps.. 🙂
