I have a Web page where I update the HTML table regularely.
The very section with the HTML table element, I edit in XXE: I havecreated an XML document in the HTML namespace, with the followingdocument structure:
<div xmlns="http://www.w3.org/1999/xhtml";><table/></div>
(Thus, there is no DOCTYPE or <html> or <body> — or any other of theelements that are required in a valid HTML document.)
And thus, every time I need to edit the table, I create a new file withthe above document structure, and edit in XXE, before I paste the codeinto the Web page.
I/We have worked this way for some years.
But this week, I noticed that even when I open old documents, extranamespace declarations are added, like so:
<div xmlns="http://www.w3.org/1999/xhtml";
xmlns:xxe="http://www.xmlmind.com/xmleditor/namespace/extension";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:svg="http://www.w3.org/2000/svg";
xmlns:ns="http://www.w3.org/1999/xhtml";
xmlns:mml="http://www.w3.org/1998/Math/MathML";>
I think might be the first time I saw these declarations in thedocuments of this particular project. But it is not the first time Ihave seen it, as such.
Anyway, I just wondered if this is due to some XXE setting that I mighthave edited?


I don't see which setting this could be.

Or if it is an XXE bug?

Even if all these namespace declarations are not useful, they are prettyharmless.

Or what? The version XXE where thishappened, is version 10.10

I'm sorry but I cannot reproduce the issue you describe usingforthcoming XXE 10.11 (identical to XXE 10.10 when it comes to savingXHTML files).


1) I've created attached table_template.html

---
<div xmlns="http://www.w3.org/1999/xhtml";><table/></div>
---

2) I opened this file automatically detected by XXE as being XHTML5 andI've added a tbody, tr, td, etc, to its table.



3) I've inserted a MathML expression and I get attached table1.html.
