Re: [Vtd-xml-users] VTD 2.13.1: No TOKEN_ENDING_TAG tokens

Hi again,
I’m afraid the combination of TOKEN_STARTING_TAG and depth is ambiguously. Text tokens and property tokens (e.g. TOKEN_PI_NAME) have the same depth as the element starting tag.
To have explicit TOKEN_ENDING_TAG tokens would be really helpful and enhance the usability of VTD-XML a lot. I am fighting half the day for reliable way to tell whether I’m still in a specific element or not. I will make it eventually, but by now I wished I would just have used StAX. I would have finished hours ago if I had. Actually I’m thinking of changing to StAX right now, might be quicker…
Best,
Erik

That means that when a TOKEN_START_TAG token is encountered, a specific class is called that processes the current element. For this, the called class iterates over the tokens until it finds the end of the element. I thought I could just wait for a TOKEN_ENDING_TAG token and check if it matches the original TOKEN_START_TAG and the token depth of the start token. However, it seams that absolutely no token is of type TOKEN_ENDING_TAG in the whole document. My code:
