[FMX] XML retrieve and write

Hello,

I’m working on a project with settings in a cinfig.xml file. Here are links to
html files and images. I want to apply a sort of CMS to this and I made a form in Flash that retrives all variables that I want in the correct way.

But the question is:
Can I retrieve my variables in my Flash form, change and modify, then send them back where they came from in the xml file ???
So not to generate a whole new xml file by PHP. So the way I retrived my varibales I want after changes these to overwrite the existing with the new variables…

Can anyone give me an example or good hint how or IF it is possible,

friendly regards
