329def replace_string(self, string, search_for, replace_with, count=-1):
330 """Replaces ``search_for`` in the given ``string`` with ``replace_with``.
331
332 ``search_for`` is used as a literal string. See `Replace String
333 Using Regexp` if more powerful pattern matching is needed.
334 If you need to just remove a string see `Remove String`.
335
336 If the optional argument ``count`` is given, only that many
337 occurrences from left are replaced. Negative ``count`` means
338 that all occurrences are replaced (default behaviour) and zero
339 means that nothing is done.
340
341 A modified version of the string is returned and the original
342 string is not altered.
343
344 Examples:
345 | ${str} = | Replace String | Hello, world! | world | tellus |
346 | Should Be Equal | ${str} | Hello, tellus! | | |
347 | ${str} = | Replace String | Hello, world! | l | ${EMPTY} | count=1 |
348 | Should Be Equal | ${str} | Helo, world! | | |
