The OP asked "Has anyone else had trouble with the XML package lately
and if so, how did you resolve it?"
For what it's worth...
I failed to install XML using install() with the defaults; I can't
remember the exact error message, something about access denied.
Downloading XML_3.98-1.1.zip with Internet Explorer
<http://cran.r-project.org/bin/windows/contrib/3.2/XML_3.98-1.1.zip>
gave a more informative error:
========================
Threat Source: http://cran.r-project.or...trib/3.2/XML_3.98-1.1.zip
The file requested could not be scanned by Sophos Anti-Virus. This means
it could be encrypted or may contain errors that prevent full scanning.
As a result, the file was blocked from downloading.
=====================
... so my access was blocked by our systems anti-virus.
Our IT people bypassed the anti-virus to download the zip from which I
successfully installed.
I note that in the library as installed there is a file
...\XML\exampleData\dtd.zip
Double-clicking in Windows Explorer gives an error:
=========
Windows cannot open the folder. The Compressed (zipped) Folder ... is
invalid.
=========
I speculate that Sophos Anti-Virus could not scan dtd.zip because it
tried to open it as a zipped folder and failed. I don't know if it
really is a zipped folder or if that's just its name :-O
This 2013 thread seems relevant

This really should have been sent to the package maintainer. But that
the zip file is corrupt has been reported several times, and does not
block installation for anyone else, so your (plural) diagnosis is wrong.

I have been attempting to install the R devtools package at work. The
version of R is 3.1.2 (Pumpkin Helmet). However, the installation of
devtools fails because devtools depends on rversions which in turn
depends
upon the XML package (XML_3.98-1.1.tar.gz), and the XML package is not
importing correctly for us.
One of our system administrators tried scanning through the files in the
XML package, and he said that the particular file:
/src/contrib/XML_3.98-1.1.tar.gz/XML/inst/exampleData/dtd.zip looks
corrupted. The actual error message he received was: "Archive parsing
failed! (Data is corrupted)." For the record, I tried downloading an
older version of the XML package (XML_3.95-0.1.tar.gz) but that was also
without success -- this time there was a separate error message about not
being able to locate xml2-config. (Perhaps XML_3.95-0.1.tar.gz is
just not
compatible with R version 3.1.2?)
I tried browsing over to the "CRAN checks" link for the XML package and
noticed several red warning messages under the "Status" column -- not
sure
if that is typical? Has anyone else had trouble with the XML package
lately and if so, how did you resolve it? Would it be possible to remove
the potentially corrupted file and then re-upload the package source
XML_3.98-1.1.tar.gz to the CRAN webpage? Thanks for your
help/suggestions!
