[xml] Length xmlTextReaderConst... contents?

[Ralf Junker <ralfjunker gmx de>]

Hello Group!

When I parse huge (several GB) XML files with xmlTextReader, I use the "xmlTextReaderCont..." family of functions to retrieve various text contents, for example:

  xmlTextReaderConstName()
  xmlTextReaderConstValue()

>From the documentation I conclude that the "const" functions grant fastest access because no data has to be copied.

While this works fairly fast, I still need to strlen() through some million pieces of #0-terminated text to determine their lengths.

So here is my question:

Is the text length already stored within xmlTextReader so I can just call a function to retrieve it quickly? I am sure that this would be considerably faster than calling strlen() on gigabytes of text.

Many thanks,

Ralf
