The only alternative is to browse large results in TestComplete 3.0 using the Load Results... command of the Test Log panel's context menu: right-click somewhere in the Test Log panel and the select the Load Results... menu item.
You could also try a .xml to .csv converter for this jayanth.
Dump your .xml file into .csv, then parse the .csv file into Excel or another such reporting tool. I found this works very well for big logs, and gives me the ability to create graphs etc for management.
If you can automate this process you can workaround this issue.
If you want to ultimately display your logs in a web browser, you can still use .csv. I am not 100% sure of how to do it, I have very limited web programing knowledge, but I have seen the technical debate on XML vs CSV for certain web based applications. Perhaps you can search and see if there is a way to call in your csv into a web page rather than pure XML (apparently it can be signifigantly faster).
I hope that helps some [img]images/icons/smile.gif[/img]
