in reply to How perl debugger breakpoint works?

When compiling code with the debugger active, Perl replaces what would normally be nextstate ops with dbstate ops. The latter check for breakpoints when encountered. See pp_dbstate in pp_ctl.c.

    Where does Perl replace nextstate with dbstate?

    When I search OPf_SPECIAL,there're too many stuff popped up..

      See the newSTATEOP function in op.c. The optree generator calls this function during compilation.

[Discipulus]: so every library (js) to sdelect and modify the id parameters can be good.
[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..
