XML linter with schema validation

[jtojnar]

I wanted SublimeLinter to automatically validate XML against XSD, but this AFAIK isn’t possible so I made a wrapper for xmllint utility to find XSD file in source code and pass it as argument to xmllint. Because XSD paths can be relative I had to change linter to pass path instead of content so I could detect XSD file path.

Currently the wrapper is quite stupid but it can be changed when I come across something that doesn’t work.

Based on SublimeLinter/SublimeLinter-xmllint@3e855400a5f47c8b4989cc06081a3781af443a79 Tested with xmllint: using libxml version 20901 and Python 2.7.6

https://gist.github.com/jtojnar/5851893

This feature should be probably implemented into libxml but I am posting it here as it is faster solution than filing a patch.

how to test this fork?

[jtojnar]

Just replace respective files in your plugin directory. Should be still compatible.

[dmaglio]

the first file, "liinter.py" it's an error or it's correct?

[jtojnar]

Yes, sorry. Updated the gist with instructions and python 3 compatibility. It doesn’t display some errors though, not sure why (they are displayed in console when lint debug is enabled). I usually use this tool around July so I currently lack will to further debug it.

SublimeLinter: xmllint output:
  File "/usr/bin/xmllintschema", line 25
    print('-:' + str(schemaline) + ': Schema file does not exist', file=sys.stderr)
                                                                       ^

Do you use python 3 (Sublime 3)?

[dmaglio]

yes

This error is thrown by python 2. You can try the previous revision.

[dmaglio]

Nothing....

SublimeLinter: xmllint output:
Traceback (most recent call last):
  File "/usr/bin/xmllintschema", line 11, in <module>
    with open(sys.argv[-1], 'r') as f:

Have you also changed linter.py accordingly?

[dmaglio]

Yes, now work without error but don't show error in sublime... if i try to use xmllintschema into console work correctly

Do you use 'Save Only' linter mode? The problem with this linter is that file path is passed to xmllint (it is needed to figure out the path to schema file) and it has no way to see unsaved changes :( Only way to fix this is integrating xmlllintschema to linter.py.

my lint mode is background. this is my preferences:

OK, created fork with xmllintschema incorporated in the plugin. Just replace linter.py

[dmaglio]

Perfect, work correctly :)

@jtojnar your fork works great, except the errors that are found when validating against the XSD schema pop up only in SublimeLinter's "Show all errors" not when having the cursor over the line that has the error.

It seems it is because the formatting of such errors is a bit different from simple XML validation. SublimeLinter is only able to get the line. My regex is rusty, will survive with just "Show all errors".

[jtojnar]

For me it displays the error even when cursor is on the line. Though I discovered different bug: when there is an error in schema, the error is displayed on the same line in the validated file.

[Pendrokar]

Forgot to note, I'm on Windows. Perhaps that is the reason why it is happening to me.

[jtojnar]

Weird. What do you see in the console when you enable debug in SublimeLinter config?

[Pendrokar]

Ah I see, it is because there are two errors on a single line, any other one line error shows correctly: -:16: element PersonalityTraits: Schemas validity error : Element 'PersonalityTraits': [facet 'enumeration'] The value 'Aggressives' is not an element of the set {'... -:16: element PersonalityTraits: Schemas validity error : Element 'PersonalityTraits': 'Aggressives' is not a valid value of the atomic type 'PersonalityTypes'.

when i set args for xmllint, sublime report

SublimeLinter: xmllint: account_assert_test.xml ['c:\cygwin\bin\xmllint.exe', '--noout', '--relaxng e:\odoo.rng', '-'] SublimeLinter: xmllint output: Unknown option --relaxng e:\odoo.rng

but when i run it out of sublime, it worked,

C:\Users\w541>xmllint --noout --relaxng e:\odoo.rng e:\odoo\addons\account\account_assert_test.xml e:\odoo\addons\account\account_assert_test.xml validates

[jtojnar]

@jeffery9 Try using '--relaxng', 'e:\odoo.rng' otherwise it might be enclosed in quotation marks and considered one option.

[jeffery9]

@jtojnar thanks, it worked.

[braver]

Sorry for letting this sit here so long. I don't think we'll be incorporating this into the plugin, but feel free to publish the fork.
