Dear Statalist,
i have a problem with the implementation of the regular expressions in stata;
i try to match (actually replace) one ore more single double quotes
(") nested within a string variable (as this is typical for example
some company names, e.g. "Hotel "ABC"");
Since there is no escape character for "normal" characters but for
example the regular expression anchors ^ or $ i can't do (as this is
the case e.g. for the script language AWK):
.generate x=regexr(company,""","") or
.generate x=regexr(company,"\"","")
which both give the error
.too few quotes
.r(132);
The same is (of course) true for using the string function subinstr:
.generate x=subinstr(company,""","",.)
too few quotes
r(132);
To be clear: suppose one company name in the variable company is
"Hotel "ABC"", so i want to replace the double quotes within the
string to get "Hotel ABC" (or say Hotel ABC without any quotes)
Is there a way of escaping the quotes so i can match them using the
regular expression implementation or is there another way of replacing
them using the string functions?
Thanks in advance for any hint why i'm wrong or any idea on how to
solve this problem.
Best regrads,
Tobias Gramlich
