Good morning,
Yes the spaces are due to the fact of the multiple copy-paste between the word processor, the translator and the absence of a code block.
In fact I was wrong, I thought it worked under Regex 101, because it automatically copies in the substitution area, I had not been careful. But in fact it is like in Sigil, it only finds with an occurrence of the chain, while I ask with or without.
I would have liked, as far as possible, with the same regex (because of course, I could treat in 2 passages):
- Find all links; Whether or not this first channel is (class or other)
- be able to modify, for example group 5 of all links
- Do not postpone the channel \ 1
The quantifier ? (0 or 1), only finds 1
the quantifier * (0 or more), does not match
The quantifier {0.1}, only finds 1
Thanks
