I am using QTP for automating an application. QTP recognizes Java applet- JTree as a html tag. In the html tag we have a number which is dynamic.
Hence we used Regular Expression so that QTP recognizes the object even if the number changes. But QTP is failing to do so. We have tested the regular expression in the evaluator and it works highlights the correct number as expected. 
The expression in Obj Repository matches with the one in the Expert view.

Reg expressions do not work with html tags/applets is it?? 

Is there any other way to deal with dynamic elements in html tags??

Thanks in advance.
