HTML subfilter is an option in many filetypes, but it's not available for XLIFF 1.2 and 2.0, SDL XLIFF, Trados TTX, and TXT.
Available workaround (if any):
Converting <[^>]+> to tags, but that is of limited use.
Add HTML subfilter option for XLIFF 1.2 and 2.0, SDL XLIFF, Trados TTX, and TXT (where possible).
More and more localization platforms use XLIFF formats with HTML tags (even though it is not allowed). In many cases, these are paired tags.
The above workaround does not create paired tags, so legacy TM matches containing paired tags need adjustments, and the saved translation units also will contain unpaired tags. The handling of HTML entities such as " or ' is also problematic.
