Currently if you parse multiple files with the same Parser instance, you get different results in the error reporting since the parser doesn't reset the offset.

How to reproduce

If you remove the line added in the parser then the error message shows the incorrect line number and the test will fail.

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

  • Always add tests
  • Keep backward compatibility (see https://symfony.com/bc).
  • Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
  • Features and deprecations must be submitted against the 6.1 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Carsonbot

Looking at the properties, the reset is also missing for refsBeingParsed

This is true and on some objects the offset is getting reset back to 0. I haven't really dug into the code of the parser.

Should I also add a reset for the refsBeingParsed even though I don't know how to reproduce the error in a test?
