I have a zip file xxxx.zip which have one xml xxx.xml file and another zip aaaa.zip file as an attachment. I need to extract the xxxx.zip and I need to replace one of the string in xml and again I need to zip the xxx.xml and aaaa.zip back to xxxx.zip. Can any one suggest how I can go about.
How complex is the XML change? If it's just text replacement, you may be able to do it with string operations, but if it involves structural changes you should use one of the available XML APIs (DOM or SAX).
Since the question has nothing to do with servlets -which this forum is all about- I'll move it to a more appropriate forum.
