<p style="margin-left:.5in">Hi Jim,<o:p></o:p></p>
<p style="margin-left:.5in">Regarding installing XML::LibXML on EPrints, I think the page that you may have seen the guide for how to install this was on the EPrints installation page for Debian / Ubuntu:<o:p></o:p></p>
<p style="margin-left:.5in"><a href="https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.eprints.org%2Fw%2FInstalling_EPrints_on_Debian%2FUbuntu%23Installing_EPrints_from_Source&amp;data=04%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C06690bd6e20242d2c41308d9da500ad8%7C4a5378f929f44d3ebe89669d03ada9d8%7C0%7C0%7C637780860469418111%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=Dgy4xI%2BlTdwf30tjPdevTxna2%2Fey1uoXynoQNRa5Q%2B8%3D&amp;reserved=0" originalSrc="https://wiki.eprints.org/w/Installing_EPrints_on_Debian/Ubuntu#Installing_EPrints_from_Source" shash="wAt0y5RzKuDSFOMFk9p9mUaRfC0eujqySZ2VU2xVxbV93polSBalzscIDH21s/hoTknvtG+AJTKbpjsvY9gURPiV7pJNmPdVNdPhLvxZXDYloY8+k+C1dfp+Th/9eVYP6Z7sdi3K7dba9rqz01Sg9CRKH2XXgJmllS3PF1f/fsA=">https://wiki.eprints.org/w/Installing_EPrints_on_Debian/Ubuntu#Installing_EPrints_from_Source</a><o:p></o:p></p>
<p style="margin-left:.5in">My general advice would always be to install from the OS's package manager rather than CPAN.&nbsp; You may get a slightly earlier version of the Perl module but it will get updated automatically when you do package upgrades.&nbsp; If you use
 CPAN there is a good chance this will never get upgraded until you move server again.<o:p></o:p></p>
<p style="margin-left:.5in">I don't think it matters that the version specified is 1.63.&nbsp; As I understand the use command will not complain unless the version installed is earlier than this.&nbsp; I typically run version 2.0018 at the moment and EPrints does not
 complain about this not being 1.63.&nbsp; Why 1.63 was specified is a a legacy thing before my time.&nbsp; I assume there was functionality missing in earlier versions.&nbsp; However, now no one would be using such an old version it is probably superfluous.&nbsp; Although it
 should make no difference with modern systems, it is probably best to leave the version number to use alone, to avoid any unintended consequences.<o:p></o:p></p>
<p style="margin-left:.5in">The way that EPrints XML init code works is as follows:<o:p></o:p></p>
<p style="margin-left:.5in">1. Tests if XML::LibXML is installed and returns if yes.<o:p></o:p></p>
<p style="margin-left:.5in">2. If not returned, prints a deprecation warning.<o:p></o:p></p>
<p style="margin-left:.5in">3. Tests if XML::GDOME is installed and returns if yes.<o:p></o:p></p>
<p style="margin-left:.5in">4. If not returned uses XML::DOM which is provided as part of the EPrints codebase, so will be initialised for XML as a last resort.&nbsp; This is what caused you your initial error message, as this packaged with EPrints version of XML::DOM
 has not be updated for quite some time.<o:p></o:p></p>
<p style="margin-left:.5in">I am looking towards just using XML::LibXML in later versions of EPrints, probably 3.5.x.&nbsp; This is probably a couple of years off based on current timescales.&nbsp; At which point EPrints would fail when you run &quot;epadmin test&quot; and will
 tell you how to fix (i.e. install XML::LibXML).&nbsp; As other options will be removed, I don't think there is much point updating the packaged with EPrints version of XML::DOM to address the original issue you reported.<o:p></o:p></p>
