Xml analyzer should report TODO’s and FIXME’s in XML files.
This rule is already available for go, php, JavaScript, Java, C#, Ruby and Kotlin and should also be available for XML.
They should have equivalent description, rationale, type, tags and severity than for the other languages. (See squid:S1134 and squid:S1135 for instance)
I created mines, using XPath (//comment()[contains(.,'TODO')]
and //comment()[contains(.,'FIXME')]
), but this kind of rule should be available by default.
