Xml parser in java

I am looking to develop an xml parser in java. The parser needs to have the following functionality

- parse multiple xml (around 1000) files simultaneously on a 16 core linux machine. Time taken to parse is critical
- write the parsed files into mysql db
- every object in the xml file needs to written into a separate table
- if new objects or attributes are discovered in the xml file then new tables needs to be created
- tables need to be indexed

Sample files will be provided. Please apply for this only if you have solid experience parsing xml files in java
