It looks related to broken css tags. Can somebody please clarify on this? I am using the css rules in the file to figure out certain elements on the html page (which linked to the css). Will these errors actually effect the parsing of the css rules and hence the profiling of the html elements on the web page? (I am sure it does but hope it does not)

Thanks in advance..

回答1:

Maybe because you're using non-standard CSS rules like "!ie7", or vendor specific properties like "-moz-border-radius"?

回答2:

You must escape the characters when you are parsing. Apache has the StringEscapeUtils class which can help you. I think you must use StringEscapeUtils.escapeHTML(readedText); due to html and css syntax are more similar.
