[TYPO3-RTE] Transforming data within the rte

[Jan Wulff]

Hi,

I need to place an icon before every h2 header. Doing this in the
transformed frontend output is no problem. I'm using this TypoScript to
achieve it:
lib.parseFunc_RTE.tags.h2.innerWrap = <img ... />|
But I would also like to see this icon in the RTE itself. I guess I have to
configure this in another transform directive, but I have no clue in which
one. Any ideas?

By the way, is there a recommend way to change the labels of the blockstyle
element by now? I remember, that there was a problem, overwriting them by
TypoScript, because there were named with an inner space (e.g. "Header 1").

Best Regards
Jan
