Store XML Data in an array to work with

[authe]

hi,
i'm only a beginner working with xml,
but nevertheless, i want to know,
how i can store some xml data in an array.

in my case, someone wants to login in with a username and a passwort.

in my xml file, looking like this:

<User><User_ID> AMARTON </User_ID> <User_PW> AA </User_PW> <User_First_Name> Andor </User_First_Name> <User_Last_Name> Marton </User_Last_Name> <Mat_Group> 123</Mat_Group> </User>

<User><User_ID> ANAVROT </User_ID> <User_PW> AA </User_PW> <User_First_Name> Adriana </User_First_Name> <User_Last_Name> Navrotchi </User_Last_Name> <Mat_Group> 123</Mat_Group> </User>

<User><User_ID> APANTA </User_ID> <User_PW> AA </User_PW> <User_First_Name> Angelica </User_First_Name> <User_Last_Name> Panta </User_Last_Name> <Mat_Group> 123</Mat_Group> </User>

<User><User_ID> APANTAR </User_ID> <User_PW> AA </User_PW> <User_First_Name> sssssssssss </User_First_Name> <User_Last_Name> sssssssssss </User_Last_Name> <Mat_Group> 123</Mat_Group> </User>

no i want to check, if the username exists in the xml file, and if it exists, if the password is equal with the pw. in the xml file....

how can i reach this???

you could try to use regex instead of xml funcions..

$string = join('',file('filename.xml'));

$regex = "|<User_ID>$user</User_ID><User_PW>$pass</User_PW>|";

echo preg_match($regex,$string);

thats how I do it, instead of using complex xml functions for simple tasks..
