xs:maxLength and xs:minLength are not working when using xs:restrictions

[sukhpalsingh]

I was using this library and it looks like xs:maxLength and xs:minLength restrictions are not yet implemented. I would like to contribute to this project to add these restrictions and some other common restrictions too.

Can you please tell me where will be best place to add such restrictions validation in the library so that text editor will have maximum length restriction and other common restrictions that are used in xml schema.

Another person was looking at implementing some restrictions, including maxLength, but I'm not sure how far superinconnu got with it. You can see the issue here and my thoughts about how I would implement it:

#14

The second part of my answer in that post only really applies to the graphical editor. Implementing the restrictions in the text editor (preferably as highlighted or marked errors rather than interfering with user input) would require some investigation into the ajax ace editor. I haven't looked into this before, but my guess is it would involve either extending the XML highlighter or using the syntax validation mechanisms mentioned here:

https://github.com/ajaxorg/ace/wiki/Creating-or-Extending-an-Edit-Mode
https://github.com/ajaxorg/ace/wiki/Syntax-validation

Although there may be simpler ways to do what you need. Most of the direct interactions with the ace editor happen in this file currently:

Thanks for your interest!
