This is v2 from
https://listman.redhat.com/archives/libvir-list/2021-April/msg00617.html
Changes since v1:
- rebase to the lastest git master
This series reworks the outdated way of parsing XML to parsing by XPath,
which is more obvious and saves a few lines of code.

Since you are touching this strToint conversion anyway, you could have
used virXMLPropUInt(). Nothing critical, just pointing that out. It also
applies to the rest of patches. I'll fix them before merge.

Ooops. While this may work by chance, it's not correct.
virXPathNodeSet() does not return a NULL terminated array. Therefore, if
n == 1, then source[0] is allocated, but source[1] is not. Fortunately,
the fix is as easy as s/source[1]/n == 2/.

Apologies for the thread necromancy :)
If I'm reading the change above correctly, then the presence of the
compression property of the <playback> element has gone from being
required, with an error being raised and the function terminating
early if it's not there, to being parsed if found and ignored
otherwise.
Tim later restored the original behavior in

and specifically the VIR_XML_PROP_REQUIRED bit, but I can't help
wondering if there are other cases where switching to
virXPathString() in the way seen here might have introduced undesired
changes in behavior.
Thoughts?

Unless you want to audit every virXPath*() call with its history, I say
we're good as we didn't get any bug reports. It is unfortunate, but the
master was broken only for one day.

Unless you want to audit every virXPath*() call with its history, I say
we're good as we didn't get any bug reports. It is unfortunate, but the
master was broken only for one day.
I'm not concerned about the brief period of time between Kristina's
and Tim's patches were merged, but about any subtle changes in
behavior that might still be lingering even after a year.
That said, I have just finished auditing all uses of
virXMLPropTristate*() and I don't think I can find the strength in me
to go through the same process again for virXPath*() - at least not
right away.
So let's just hope that the lack of bug reports is an accurate
indicator of the lack of significant regressions, I guess :)
