Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 Jiri Popelka 2013-08-16 15:54:15 UTC 
There's been also an upstream ticket for this:
https://fedorahosted.org/firewalld/ticket/8

I've actually already had some XML Schemas,
but have no idea how to correctly incorporate them:
https://git.fedorahosted.org/cgit/firewalld.git/tree/config/xmlschema
Comment 7 Thomas Woerner 2014-09-29 23:50:21 UTC 
Moving to 7.2
Comment 9 Jiri Popelka 2015-04-01 08:40:19 UTC 
Since upstream version 0.3.13, we've been including XSD (XML Schema Definition) files in the tarball. These are installed into /usr/lib/firewalld/xmlschema/
Comment 10 Thomas Woerner 2015-07-06 13:58:12 UTC 
The xml parser in python-libs (expat) does not support validation with DTD or schema. The error from the xml parser is "SAXNotSupportedException: expat does not support validation"

A switch to a another parser is not possible easily. Therefore this request can not get fulfilled with integrated validation.

A possible solution is to do manual verification with an external tool, like for example xmllint from the libxml2 package using the schema files from comment 2.
Comment 11 Thomas Woerner 2015-07-06 19:37:10 UTC 
The requirement for libxml2 will not be added on top of the existing requirements.

The check script provides information about missing xmllint and how to fix this.
