The perl regular expression you are looking for is
s/\/\*.*\*\///
Remember that * and / are special characters and need to be escaped as \*
and \/
So, the expression above reads
s/ -- start of substitution
\/\* -- match /*
.* -- The means any non newline character (This would include the / that
you had in your second example
\*\/ -- match */
// -- replace the matched expression with nothing (in otherwords, remove
it)
That would work as long as the /* and */ are on the same line
Not sure how to do this with ORO

> Hi,
> my name is Luigi Zoso and I'm currently trying to automatically remove
> comments from files containing Javascript code, by using jakarta-ORO's
> "Util.substitute()" API. I built a java class by following the guidelines
> of substituteExample.java.
> I'm experiencing some problems when I try to delete comments of the type:
> /* This is a comment */
> The problem is to find the correct regular expression in order to match
> these comments and replace them with a blank string in the file.
> At present, I use the following expression:
> (\/+[\*]+[^\*\/]+[\*]+\/)
> I put the "[^\*\/]" in order to avoid removing code between two comments,
> like in this example:
>
> /*First comment*/
> Function myFunction()
> {alert("I don't want to delete this code");}
> /*Second comment*/
>
> This works for simple cases, such as single comments isolated from the
rest
> of the code, but it fails with more complex cases such as when a "/" is
> present inside the comment:
>
> /*First comment*/
> Function myFunction()
> {alert("I don't want to delete this code");}
> /*Second comment with / inside it */
>
> Could anyone help me with a more useful regular expression?
