pack download failures
"pyocd pack find stm32l" does not seem to work on across a few versions of pyOCD as well across linux and windows. In particular this did not work for when I was trying to do it for the stm32l011, but it does not seem to find any packs with the name stm32l.
Have you tried to run pyocd pack update first?
I just tried the following:
$ pip install -U pyocd cmsis-pack-manager
[...]
$ pyocd pack update

I did try that pyocd pack update, but I get a similar issue to tonika31. It does not seem to update properly as the pyocd pack find stm32l command still does not work after that.
@carlVirtualincision / @tonika31: what versions of pyocd and cmsis-pack-manager packages are you using?

I'm trying this on both my Windows host, as well as Ubuntu 22.04 under WSL2 and getting the same result. I also tried rolling back to earlier versions of PyOCD and cmsis-pack-manager with no luck.
A new version of cmsis-pack-manager (0.5.2) is being published that addresses an issue where PDSC file downloads might fail because too many downloads are started concurrently. This might explain the different observations in this issue.
I have pyocd .0.34.3 and cmsis-pack-manager 0.5.2 and I cant update. If I try I get the same XML error and more as @elliott-col posted.
Any fix?
@larsfagerbakke We haven't been able to reliably reproduce any issues since cmsis-pack-manager v0.5.2. I have seen errors downloading only NXP packs on very rare occasions, but they immediately went away next time I tried. @mathias-arm hasn't seen the errors at all, afaik.
Could you please provide the log output you see? The "XML error: Expecting </P>…" errors were caused by mishandling of errors in earlier versions that resulting in downloading of HTML responses to 404 errors (returned by the server because of too many simultaneous requests). CPM now correctly handles HTTP error responses (not taking into account possible bugs), so it won't try to parse HTML pages and therefore should not report similar XML parsing errors.
The errors from 404 responses now look like this (clearly not the most user-friendly):
20:12:31 [ERROR] download of Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("ziweixing.workspacep5.webfoss.com")), port: None, path: "/uploads/XMC.CX32L003_DFP.pdsc", query: None, fragment: None } failed: Response code in invalid range: 404
(This is from a pack hosted on a server that apparently isn't running anymore, or the vendor provided an invalid path.)
So, if you are still seeing XML parsing errors, there's something new and different happening, or a variant of a previous problem.
Note that you can always download CMSIS-Packs manually from https://www.keil.com/dd2/pack/ and use the --pack argument with pyocd (or the pack session option). See the docs for more.
@mathias-arm I think the error @larsfagerbakke reports is the one I saw but couldn't reproduce.
