SAX praser passing element's attribute value dynamically

[shabarish vai]

Hi all,
i have very poor knowledge in XML .

Am using SAX parser to parse a xml file.

my question is by passing element's attribute value dynamically can i get element details and list of elements.

for example

  
<employee type="permanent">
      <id>911</id>
     <name>shabarish</name>
</employee> 
<employee type="contract">
     <id>911</id>
      <name>likhitha</name>
</employee>

by passing employee type can i get the list of users i.e user details using SAX parser.if so how to do please provide with sample code.

thanks,
Shabarish.V

Do you mean that -given one of "permanent" or "contract"- you want the parser to ignore all employees of the other type?

If so, you could set a boolean "ignore" to false/true in the startElement method of the DocumentHandler, depending on the value of the "type" attribute. All other code in the DocumentHandler can then skip processing if "ignore" is set to true.

Alternatively, you could write an XPath expression that returns only employees of a suitable type. Then you'd be working with DOM, not SAX, though.

A good starting point on how to perform XPath processing in Java is this article: http://www.ibm.com/developerworks/library/x-javaxpathapi.html

The XPath standard is also helpful reading.
