Bug 55233 – XSL transformations do not handle errors

• Component: Layout and Rendering
• Status: UNCONFIRMED

[Vsevolod Vlasov]

When there was an error applying XSL transformation, the blank page is shown or sometimes the previous page content keeps showing.
Firefox reports such errors.

This looks pretty cool, but we'll need some tests!  (I didn't review deeply.)

> Source/WebCore/xml/XMLErrors.cpp:68
> +            m_errorMessages += "warning in " + sourceURL + " on line" + String::number(position.m_line.oneBasedInt()) + " at column " + String::number(position.m_column.oneBasedInt()) + ": " + m;

Is there an XSS risk here?  Should we sandbox error pages to be extra-sure?

[Karl Rackler]

I removed those expectations for fast/frames/onlyCommentInIFrame.html here because the test was passing consistently
