in reply to change [A-Z] to U, [a-z] to L with one regex?

You can always use $_:

$_ = "SomEThingWithMIXEDRegiSter\n"; y/A-Z/U/, y/a-z/L/; print;

Yes, this is technically still two expressions, but as others have stated, it'll be efficient, and to me, anyway, the comma operator has good semantic meaning, here, even though a semicolon would do just as well.

Update: Corrected bracket typo in y///. Thanks jwkrahn.

[Discipulus]: I never understood something: I can on the fly modify the XML structure of the SVG using for example XML::Twig ?
[Corion]: Discipulus: If you want to rewrite the SVG, then yes, something like XML::Twig should be enough. I would try to not modify the SVG but only modify the display, but so far I haven't convinced IE to change the style...
Corion gives up
[Discipulus]: ah! so you mean if i need a static image i can use Twig, if on the fly better css selector and mody attrs (jquery?), rigth?
[LanX]: not sure what you guys are taking about, but a DOM manipulation in JS shouldn't be difficult
[Corion]: Discipulus: Yeah, that's what I would try (but so far, I can't even change the colors manually in the SVG, which is why I gave up ;) )
Discipulus bad sign..
[Discipulus]: italian doc says to modify somehow the initial SVG before using it with D3.js
