RE: Invalidating empty element and returning line and column numb er

["Koziol, Jason" <ja...@sap.com>]

What is wrong is that it seems like I'm missing something.

For example, I'm in SAXPrint, and I want to modify the following method

void SAXPrintHandlers::endElement(const XMLCh* const name)
{
    cout << "</" << StrX(name) << ">";
}

so that it also prints out the line and column. My instincts, based on
whatever experience or lack of experience they may be, tell me I should
be able to do this in short order. But everything I can think of
involves a seemingly disproportionate amount of effort. Maybe you can 
tell me what you would do here?

A colleague promised me that you all would probably assume I was stupid.
That is just fine with me. :-)

BTW I am working in Win32.

Thanks

The locator is implemented in the most recent code, so it will work in the
upcoming release. But, the locator is really just the reader manager (which
implements the Locator interface.) The reader manager stuff obviously works,
since that's where all the line/col info comes from that are in any error
messages. What exactly do you feel is wrong?

Re: Invalidating empty element and returning line and column number

[Dean Roddey <dr...@charmedquark.com>]

In the upcoming release, you'll just intercept the setLocator() method and
remember that locator object and ask it for that information. In the current
code, you would probably want to do something in the constructor for your
document handler where you store a pointer to the reader manager.

// Inside your document handler constructor
ReaderMgr* fRdrMgr = &fMyParser.getScanner().getReaderMgr();

// Inside some subsquent event
fRdrMgr->getLineNumber();
fRdrMgr->getColumnNumber();
....


That's not as convenient as it will be when you can just get the locator,
but its not terribly onerous either. Don't know why your friend told you
that we would think you are stupid. I would assume that he had some belief
and we didn't agree and perhaps he interpreted that as us thinking he was
stupid or something. I dunno, but I only think someone is stupid if they ask
a question that is like the second answer in the FAQ or something like that.

Note that I'm going by the current code, so I might have flubbed something
relative to the existing 3.1.0/1.1.0 release. If the getLineNumber() and
getColumnNumber() methods aren't there on reader manager in that release, do
this:

fRdrMgr->getCurrentReader()->getColumnNumber();
fRdrMgr->getCurrentReader()->getLineNumber();
