How to fix: XML tag mismatch

One or more products in your data feed contain a pair of opening/closing XML tags that don't match. Any product containing this error will be skipped. However, other properly-formatted products in your feed will still process. A closing tag must always match the most recent opening tag in the feed. For example, this XML would generate an "XML Tag Mismatch" error:

<g:event_dateTime>
<g:from>2005-12-20T14:00:00
<g:to>2005-12-20T19:00:00</g:to>
</g:event_dateTime>

The XML generates an error because the attribute tag <g:from> doesn't have a matching end-tag </g:from>. Each attribute tag must be terminated by the matching end-tag:

<g:event_dateTime>
<g:from>2005-12-20T14:00:00</g:from>
<g:to>2005-12-20T19:00:00</g:to>
</g:event_dateTime>
