    how to validate user-generated html is well-formed?

    Reply Quote
    I'm not talking about validating to w3 specs. I just want to ensure that the html that the user creates is 'well-formed' so that it doesn't screw up my 'host' page when it is displayed, because of missing closing tags, etc..
     
    Does anyone have any method to achieve this? Even an imperfect solution will be welcome (and better than nothing).
     
    Thanks.

    Hi pw007,
     
    By default, editor will close the tag directly.
     
    1. Please open http://www.cutesoft.net/example/general.aspx
     
    2. Clean the content and input the code below into HTML view
     
    <p>this is a test
     
    3. When you switch back to the Normal view, eidtor will close the <p> tag, like below
     
    <p>this is a test</p>
     
    Regards,
     
    Ken

    Hi Ken - thanks for this. That behavior is definitely a start. But I wouldn't expect your product to be able to correct ALL invalid html (pretty impossible!).
    However, I would really like a way (either within your product or using some available code) to  just be able to validate that the html is well-formed. If a user creates poorly-formed html I will just reject it - otherwise his bad html could screw up my pages when displayed.
     
    Also - does your product itself always generate properly-formed html? (e.g. if the user doesn't manually edit the html).
     
    Thanks,
    Paul.
