The main use case for split_sandwiches()
is for html editing: You might want to separate the original text from the html tags, make certain edits to the text only, and then re-wrap the tags.
This is different from str_split()
or similar, because the delimiters are preserved and remain attached to a section.
Note that split_sandwiches()
is not vectorized (sorry). It only takes a single character object.
A vector of strings
1 2 3 | my_string <- "<span style='text-color:blue'> I am blue and <b>bold</b>, yay! </span>"
split_sandwiches(my_string, "\\<[^\\>\\<]*\\>")
