Re: best xml parser to use

I'd go with a DOM-style API (either DOM, JDOM, dom4j, or XOM). The files aren't that big. Using SAX or StAX will require that you build up the extracted string manually, whereas with DOM the process looks like:
1) parse document
2) loop through invoice child elements 3) serialize each child element to a String and post
You could use xmlbeans or another data binding framework, but then you're just subsituting the generic DOM data model for a schema-specific data model. It doesn't sound like you care about the internal structure and content of an invoice, so generating the new Java classes required for data binding is unnecessary overhead.

You need to compile the schema which returns java code that will then allow you to directly reference any element. Then, simply reference the invoice structure's topmost element, and then do as you wish, either write the xml to the queue as simple text, or create a new xml document (just provides the xml header at the start of the file) and add only this copied element to it and write to the queue, or strip all or selected, etc..., etc..., and write to the queue and iterate to the next invoice or batch file. It could be 20 lines of code tops.
If you don't have a schema to feed into the schema compiler there are a couple of tools that you can build a schema and a couple that infer schema from sample xml.

Hi
I have a particular problem to solve:
I have an xml batch file that contains individual xml invoices. I need to
extract these xml invoices one at a time and place them on a message queue i.e. I just need to get all the data between the invoice start and end tags put it in a string and place it on a message queue (validation occurs on the
invoice itself on the receiver side).
What is likely to be my best approach, DOM (unlikely I guess), SAX, StAX or simply writing a java program using indexOf, in terms of performance ?
TIA Peter
