How to read full xml file including tags and modify contents

[freddo]

I wish to read an xml file, change a couple of lines and write it out again. However when I use
fgets, fopen() or fread() PHP strips off the tags and only leave the contents.

I want to be able to read the full file including tags and xml header into an array.
How can this be done?

Post some code... it shouldn't be doing that.

THanks ADNI18. Have solved the problem by reading the whole file into a string and manipulating form there.
