Hi there!
Just two possibly incompatible thoughts on that:
1.) What about using regular expressions like you can do in java or perl
with the search string being a regular expression and the replacement
String having the possibility to contain /$1 /$2 /$3 etc. with the
meaning to replace with the match found for the n-th group surrounded by
brackets inside the regular expression?
Not sure how that relates to the problem of replacing placeholders in a
fixed text with dynamic content.
The Boost library which AFAIK we already use for something else does
contain support for regular expressions.
Have a look at:
http://www.boost.org/libs/regex/doc/index.html
http://www.boost.org/libs/regex/doc/non_standard_strings.html
2.) What about using arrays of Strings as arguments instead of just
Strings? This would be adding the possiblity to replace multiple
patterns at the same time while eliminating your problem one mentioned
as well. And it will likely be faster than multiple calls to one replace
method with different patterns and replacements.
Kind regards,

Yes, functionality to solve the above problem ("replacing placeholders
in a fixed text with dynamic content") would probably use some sort of
dictionary to map different placeholders to actual content, and do the
complete conversion in one call. But that is somewhat off topic; all I
wanted this thread for is to argue that adding some searchAndReplace to
rtl::OUString is probably not as useful as it might appear at first
sight. How the functionality really asked for in the corresponding
issue should be implemented is worth another thread.
