--drop-proprietary-attributes yes --strict-tags-attributes yes causes tidy to report error instead of dropping non-applicable HTML attributes #688
Description
[Bug] According to the quickref, when both drop-proprietary-attributes and strict-tags-attributes are enabled, tidy should drop attributes that are not applicable to the HTML version. In reality, tidy reports errors instead.
Environment
- HTML Tidy for Windows version 5.6.0
- Windows 8.1
Command
tidy --strict-tags-attributes yes --drop-proprietary-attributes yes test.html
I also tried switching the order of the options but the issue persists.
Input
test.html
<!DOCTYPE html>
<html>
<title>Testing</title>
<body>
<table>
<tr>
<td align="left" valign="top">Hello whirl!</td>
</tr>
</table>
</body>
</html>Expected Output
Non-applicable attributes align and valign should be removed from <td>
<!DOCTYPE html>
<html>
<title>Testing</title>
<body>
<table>
<tr>
<td>Hello whirl!</td>
</tr>
</table>
</body>
</html>Actual Output
line 7 column 5 - Error: <td> attribute "align" not allowed for HTML5
line 7 column 5 - Error: <td> attribute "valign" not allowed for HTML5
Update
Apparently it works as expected if you include the option --force-output yes. This is non-ideal though because I want it to generate output if it's just non-applicable attributes and to fail if it's some other error.
