java code and SAX

Hi all,

I am having one xml file which has contents something like this.

<studentTree>
<student id="1">
<name>jason</name>
<subject>Maths</subject>
<subject>Chemistry></subject>
<student>
<student id="2">
<name>John</name>
<subject>Science</subject>
<subject>History</subject>
<student>
</studentTree>

I am parsing this XML using SAX parser. I have written a code something like this.




I want to get values from my xml into objects.
for example,

1st iteration
studentinfo.getId() should give me value :1
studentInfo.getSubjects() should give me : Maths,Chemistry

2nd iteration
Value:2
studentInfo.getSubjects() should give me : science,history.

The problem is, I am not able to get subject values in the list as the element name(subject) is same. Could anyone please help me out in this ?

You shouldn't create a new StringBuffer each time a subject tag is encountered. You should create it exactly once, and then clear it each time a student tag is closed.

[0] You have major typos in the xml. And then, you have not cleaned up the code StudentInfo or PageInfo class, you've to pick one and use consistently.

[1] Then apart from those, the logic of the sax parsing is clearly defective. Here is a major rewrite based on it (I pick PageInfo).

Thanks a lot for reply. Yea, I had some typos in the code. Sorry about that. Your answer resolved my problem.
