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 have
created an XML document in the HTML namespace, with the following
document structure:
<div xmlns="http://www.w3.org/1999/xhtml";><table/></div>
(Thus, there is no DOCTYPE or <html> or <body> — or any other of the
elements that are required in a valid HTML document.)
And thus, every time I need to edit the table, I create a new file with
the above document structure, and edit in XXE, before I paste the code
into the Web page.
I/We have worked this way for some years.
But this week, I noticed that even when I open old documents, extra
namespace 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 the
documents of this particular project. But it is not the first time I
have seen it, as such.
Anyway, I just wondered if this is due to some XXE setting that I might
have edited? Or if it is an XXE bug? Or what? The version XXE where this
happened, is version 10.10
I managed to reproduce this behavior by setting <saveOptions>
favorInteroperability attribute to "false" in
XXE_INSTALL_DIR/addon/config/xhtml/xhtml_common.incl
By default, this save option is "true":
---
<cfg:saveOptions favorInteroperability="true" omitXMLDeclaration="auto"
cdataSectionElements="html:script html:style" />
---
See
https://www.xmlmind.com/xmleditor/_distrib/doc/configure/saveOptions.html
Another way to reproduce this behavior with XHTML documents is to set
Java system property XXE_PREDECLARE_NAMESPACE_PREFIXES to any value,
e.g. -DXXE_PREDECLARE_NAMESPACE_PREFIXES=1
See "XXE_PREDECLARE_NAMESPACE_PREFIXES" in
https://www.xmlmind.com/xmleditor/_distrib/doc/help/system_properties.html
We'll see if we can improve this in version 10.12 not only for XHTML5
documents but also for all the document types, that is, never have
namespace prefixes which are predeclared "just in case".
It's too late to change this in forthcoming 10.11.
