[Doxygen-develop] Cannot get the correct informaition from the interfaces of 'IDocCodeLine'

[Qiuping Yi <yiq...@gm...>]

Dear all,

I am a doxygen user.

I want to use doxygen's doxmlparser to analysis the generated xml files
from C code. When I use the next code the print the line number and ref
information for each C code line:

if (comp->kind() == ICompound::File) {
            IFile *file = dynamic_cast<IFile*>(comp);
            IDoc *source = file->source();
            IDocProgramListing *programListing =
dynamic_cast<IDocProgramListing*>(source);
            IDocIterator *cli = programListing->codeLines();
            IDoc *cx;
            for (cli->toFirst();(cx=cli->current());cli->toNext()) {
                IDocCodeLine *cl = dynamic_cast<IDocCodeLine*>(cx);
                ASSERT(cl!=0);
                printf("<codeline lineNumber=%d
refId=`%s'>\n",cl->lineNumber(),cl->refId()->latin1());
            }
        }
}

I can only get the next *"empty"* information. What's wrong of my code? Did
I miss something? Thank you all in advance.

<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
<codeline lineNumber=0 refId=`'>
