问题 Could anyone suggest the best Build Tools for use in the build process when building a blackberry application. Is it just the creation of an ANT project, does that cope with signing etc?

问题 I get the HTML string from webservice. When I parse on saxparser, it throws fatal error1. Start tag (Image tag) doesn't match with end tag. Then how to get image src? And how to get div id name?
