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.

I'm expert in data processing with hundreds of excellent reviews here that's why I'm sure you'll be impressed with my work. I can create the script you want but I need to clarify one thing: are you talking about writing to MySQL directly from the script or do you still want to generate temporary XML files and load them later into MySQL? Because unescaping HTML in temporary XML files is not a good idea... Thanks. Roman

Hi there, I'm highly experienced in python/web services. I can build a more optimized xml parsing script for large files, within about a week. The exact solution will depend on how the existing service is deployed and available server resources (ram/cpu/threads/os) and processing time constraints. Please contact me if you would like to discuss the project further.

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 into mysql let me know if you have any questions. thanks kaleshwar.

Below will be my plan: 1. Understand existing script and working as a first milestone. 2. Start working on new requirement and create a basic working prototype. 3. Corner cases and exception handling as a next milestone. 4. Load testing and bug fixes will be the final milestone. Looking forward to work with you.
