Reconstituting > entity when re-parsing output

[Peter Davis]

Given a line in the editor :-

The equation small<big

The editor will correctly convert the < to an entity &gt; if this line is then re-parsed by the editor, as in a wiki, when the above page is edited, the entity is reconstituted where the document incorrectly becomes

The equation small

The source editor reveals that the following has occurred

<p>The equation small</p> <p><big></big></p>

Could you please give detailed steps to reproduce?
Could it be just a problem in your integration?

The problem can be reproduced using _samples/html/example02.html.

With a text editor, edit the textarea to read

small&lt;large

Then try

small &lt; large

In the first example "large" vanishes.

small&lt;large

That's wrong, the proper escaping for a textarea would be small&amp;gt;large.

Does this apply to all entities or just > and <

[Alfonso Martínez de Lizarrondo]

You have to escape the content in a textarea, and every server language will have the proper call that takes care of all the issues.

If you don't escape then if the content has the html "</textarea>" then that would close the textarea ahead of time. So you have to escape < and > but you must also escape & because of the problem that you had: the browser thinks that your &gt; is an escaped >
