How to check XML format (4377860)

Some common error can be seen if there is issues with incoming XML files:

024-11-19T05:49:28.137075+00:00 hostname syslog-ng[3473166]: xml-parser failed; error='Error on line 1 char 3611: Odd character \'A\', expected an open quote mark after the equals sign when giving value for attribute \'Keyword\' of element \'Keywords\'', forward_invalid='1'

The incoming XML file was not formatted correctly to be used by the syslog-ng PE XML parser.

The XML files can be checked using the XMLLINT:

Sample command:

xmllint --format /_temp/wrong.xml.raw.msg

The common error can be seen by the command:
