Develop Python script to handle large XML file using SAX parser and load to MySQL tables

Kulipwa wakati wa kujifungua
We currently have a multi-step process which loads XML data into a MySQL database on a weekly basis. A file size increase of the incoming XML files necessitates a switch to a SAX parser from the current DOM parser.
Current state:
- Existing Python script uses [login to view URL] DOM and loops through 15 weekly XML files, performing a minor transformation to each using an XSLT file, and writes transformed XML to temporary .xml files
- The temporary .xml files are loaded to seven MySQL tables using LOAD XML LOCAL INFILE
Requirements:
- Develop a Python script which replicates the above steps into a single script that uses a SAX parser which can handle XML files with size of at least 2GB
- The script should parse through each of the XML files and load the data to the target AWS MySQL tables
- Script should unescape html elements (&) which exsit in XML prior to writing to database tables (see: [login to view URL])
- Script must process files in batches (7, 7, 1) so that DB scripts can be executed between each batch
- Code should be fully commented
- If applicable, please include instructions for installation of any required modules, etc.
I will provide the following:
- sample XML file
- existing Python script
- XSLT file currently used to transform XML
- SQL which is currently used to load the MySQL tables
Please contact me for more information.

Hi, I have worked with python, and with large xml and csv files (upto 10GB in size) for a SAAS service that I was working on. I am sure I can get python to handle your xml files using SAX parser and get it imported Zaidi
