OK it turns out I did have libxml2.dll, not libxml2-2.dll. I thought I downloaded the package from ezwinports, but I actually didn't (and I don't know where I downloaded the binaries for libxml2.dll from). Downloading from ezwinports fixed the issue.

Thanks!

I'm guessing what you have in emacs/bin is libxml2-2.dll, not
libxml2.dll, yes? The package on ezwinports has libxml2-2.dll.

If indeed you have libxml2-2.dll there, this probably means some DLL
on which libxml2-2.dll is dependent is either missing or overwritten
by an incompatible version. libxml2-2.dll depends on libiconv-2.dll,
so make sure this DLL in the emacs/bin folder is the same that comes
with the libxml2-2.7.8-w32-bin.zip archive you downloaded from the
ezwinports site.

If the above doesn't help, run the dependency checker on
libxml2-2.dll, and see which other DLLs in what directories it picks
up. If you don't have the dependency checker installed, you can find
it here:
