Make code (XML parsing) Android compatible #5

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When trying to use the library on a Android 2.1 device (Nexus One), I got
the following errors - which boils down to javax/xml/stream classes not
found. Perhaps use another XML parser that is also available in Android?

Regexml uses the standard Java StAX pull parser. I didn't realize that it wasn't
available on Android. I looked into this and discovered the following:

"Java's Simple API for XML (SAX) and the Document Object Model (DOM) are both
available on Android. Both of these APIs have been part of Java technology for 
many
years. The newer Streaming API for XML (StAX) is not available in Android. 
However,
Android provides a functionally equivalent library."

It looks like the Regexml library would need to switch from StAX to SAX in 
order to
support Android. This will be considered for future releases.
