|Subject:||How to find the group information by SAX-Parsing|
|Date:||Wed, 14 Mar 2007 13:54:11 +0100|
i am now writing my master thesis and have a question about SAX:
I am trying to find the group information (sequence, choice and all) by SAX-Parsing of a xml instance, which has been defined in the XML Schema.
for example, this is the schema:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema ">
<xs:element name="name" type="xs:string" />
<xs:element name="birthday" type="xs:date" minOccurs="0"/>
and this is its instance:
<?xml version="1.0" encoding="UTF-8"?>
i want to find out by sax-parsing, that Schulz and 1970-04-15 are the attributes of the first person, the second person has the name Ferner, and the last two elements are the attributes of the third person.
Is there a standard solution for this problem? Actually the validator of the SAX Parser does have the same problem. By validating of a XML document relating to his schema the sax-based validator must also find the group information. How does it work?
I researched seveval literatures, but didn't find any solutions. They just say, that the SAX Parser has also the possibility to validate a doument and how i can start the validater and how can i handle the validating errors. The internal functionality of the validater is unknown.
I don't want to validate the whole document, but just to find the group information. So i want to know, if there has been already a solution for it? If yes, can anyone tell me, how it works or give me some sources to research?
Thanks in advance!
