Hi Ralf, Since I had a problem (error message below) compiling the DIHtmlParser samples in the trial version, so I want to ask you instead here. 1. After parsing a HTML, will the DOM tree looks like the one defined by W3C? 2. Does each node of the parsed DOM tree has a property telling the line number in the source HTML file? E.g. a <p> node should have a property called something like SourceLine/SourceCharIdx indicating it's line number and character index in the source html file. Thanks in advance.
