MAME XML Shrinker
« on: May 04, 2018, 06:58:56 am »
I use AdvanceMENU Plus for my front end. My cabinet is over ten years old, so I need something extremely lightweight and this front end does a fine job. Unfortunately, with a full MAME set, loading the front end can take a solid ten seconds as it parses the mame.xml file. The Windows command line below will only output the relevant lines. The result is a mame.xml that is roughly a quarter the size, which means the front end loads about four times as fast.

Thanks to Robbbert below who came up with the original script!

Code: [Select]
findstr /L /I "<mame <machine <description <year <manufacturer <display <input <control <driver <device[^_] </input </machine </mame" mame.xml > mame-compact.xml

FINAL EDIT: The latest master branch of AdvMenu Plus automatically shrinks the mame.xml file after it generates it. I'll leave the script up for any other future front ends.

That's pretty cool. I ended up making my own frontend and decided not to even use mame.xml because it is so huge - I only have 300+ games as of now so I made all my own stuff.

Thanks for sharing this. I will use it at some point because I do want some bigger collections and will use other frontends for that.  :cheers:

Surprised it doesnít parse the xml file once and store needed data in a csv file or SQLite database.

Iím sure people will use your tool.

I use a batch file to pull out what I need.

It has one line, and assumes you've already piped the xml to a file called xml.txt

The output of the filtering process writes the new info to xml2.txt

Code: [Select]
findstr /L /I "<mame <machine <description <disk <rom <sample <driver </machine </mame" \xml.txt > \xml2.txt

Excellent idea! I've modified it a bit so it works with the latest version of AdvMenu Plus and updated the main post. Thanks!
