mrow

/mrow
/math
would get changed to
defaultmath
defaultmrow
*snip*
/defaultmrow
/defaultmath
which of course breaks the page.
It seems to be related to the xml island concept of (x)html 5 where
for compatibility with IE and MathType etc. an xmlns is declared as an
attribute but a prefix isn't declared (IE no m:math).
To solve it, on the buffered string that gets imported I run:
function nsIsland($string) {
$search[] = /math\s([^xmlns]*)xmlns=[^\s]*/;
$replace[] = math $1;
return preg_replace($search,$replace,$string);
}
(I assume I may have to add a search/replace for svg) - then after
import I look for math nodes and add the xmlns attribute back to them,
and it seems to work.
A bit hackish, I'm guessing a future version of DOMDocument may take the
html5 xml island into consideration, but this works now.

[PHP] loadXML() and namespace
It seems that if I use loadXML($string) and the $string has a namespace defined in it, domdocument is nuking the namespace and changing the nodenames from whatever to defaultwhatever. Example - math xmlns=http://www.w3.org/1998/Math/MathML; mrow mrow msup mix/mi mn2/mn /msup mo+/mo mrow mn4/mn mo/mo mix/mi /mrow mo+/mo mn4/mn /mrow mo=/mo mn0/mn /mrow /math would get changed to defaultmath defaultmrow defaultmrow defaultmsup defaultmix/defaultmi defaultmn2/defaultmn /defaultmsup defaultmo+/defaultmo defaultmrow defaultmn4/defaultmn defaultmo/defaultmo defaultmix/defaultmi /defaultmrow defaultmo+/defaultmo defaultmn4/defaultmn /defaultmrow defaultmo=/defaultmo defaultmn0/defaultmn /defaultmrow /defaultmath which of course breaks the page. So it seems I need to somehow tell loadXML() about the namespace so it doesn't do that, but I'm not having much luck with the php manual, DOMDocument documentation seems a little on the not written side. When I create the nodes and add them to the dom via domdocument it works fine, but the issue is I like to cache the content div as a string and load it when the page is requested (stuff outside the content div needs to be dynamic and not cached) but this namespace issue prevents that. Any tips would be appreciated, caching makes a huge difference. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
