/**
*
* Called when a text artifact is found.
*
*
* A sequence of chars is considered to be text when no structures of any kind are
* contained inside it. In markup parsers, for example, this means no tags (a.k.a. elements),
* DOCTYPE's, processing instructions, etc. are contained in the sequence.
*
*
* Text sequences might include any number of new line and/or control characters.
*
*
* Text artifacts are reported using the document buffer directly, and this buffer
* should not be considered to be immutable, so reported texts should be copied if they need
* to be stored (either by copying len chars from the buffer char[] starting
* in offset or by creating a String from it using the same specification).
*
*
* Implementations of this handler should never modify the document buffer.
*
*
* @param buffer the document buffer (not copied)
* @param offset the offset (position in buffer) where the text artifact starts.
* @param len the length (in chars) of the text artifact, starting in offset.
* @param line the line in the original document where this text artifact starts.
* @param col the column in the original document where this text artifact starts.
* @throws ParseException if any exceptions occur during handling.
