Thanks very much sauoq,

Even though I can sort of read positive/negative-look-ahead regexs, I still haven't been able to exploit it effecitively in my code! Whenever I am stuck like this next time I should try out that type of solution :)

Just for other people's benefit, I shall try to explain your solution. Please correct me if i am wrong

Input: option1 = value0 value1 value2 option3 =value3 value4 option2=v
+alue5
split /(?=\s\S+\s*=)/, $line
[download]

Here the regex looks for positions where there is a space followed by more than one non-space char and then an =. When such a position is found, it splits on null char. Here, it will split right before option3 = (for the first time). We can also modify this regex slightly to make it -  /\s+(?=\S+\s*=)/.

Thanks very much.

Also thanks to QM and pg for their suggestions/solutions!

cheers

SK

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
