SAX Parser is used to parse the xml file because basically
it is for the ActionServlet to read the xml file rather
than writing something into the struts-config xml file
just the action servlet has to read the file and construts
the module config object for the one time and load it
so as SAX Parser is basically for reading and doing some
search operation Struts uses this aproach intelligently.

The Digester class parser the XML document. The Digester
framework comes with 10 prepackaged "rules," which cover
most of the required tasks when unmarshalling XML (such as
creating a bean or setting a bean property), but each user
is free to define and implement his or her own rules, as

Hi, Everybody,

Actually in jakarta struts there are two parsers.
one is DOM parser and another is SAX.

1) DOM, read the whole document at a time and creats tree
like structure.

2) SAX also creates tree like structure but with event, and
Digerster is a framework which simplifies the SAX parsing
by providing Higher level Interface to SAX events.

3)DOM is easier to implement, slower and more resource-
intensive than SAX.

4) Digerter is Originally designed to parse the struts-
config.xml, later recognized that this is more useful and
moved to "jakarta commons" project.

hense Digester is the framework which is desigened to parse
the struts-config.xml file, which inturn uses SAX parser.

See what happens is that Struts uses the Digester to map the xml data in the struts-config.xml to java objects.
Now internally digester needs a Sax parser and it could do with either a xerces/crimson parser as both are sax parsers
