Presumably, you mean XHTML or XML?  Expat and other XML parsers won't work 
on non-well-formed HTML documents, which is most.

In SAX, implement the DocumentHandler interface and register your 
implementation with a SAX-enabled parser. When the parser calls 
startElement(), you'll need to keep the element name (TEXT1 or TEXT2) as 
state. You can also retrieve attribute values at this time (they are passed 
to startElement). The parser will call characters() to pass you the text. 
Based on the state (TEXT1 or TEXT2), you can store it appropriately. Note 
that the parser can make multiple calls to characters() -- that is, it 
could call characters() five times (once for each character), once (with 
all the characters), or anything in between.
