Consider following script (it's total nonsense in pseudo-language):
if (Request.hostMatch("asfasfasf.com") && someString.existsIn(new String[] {"brr", "hrr"})) {
if (Requqest.clientIp("10.0.x.x")) {
somevar = "1";
}
somevar = "2";
}
else {
somevar = "first";
}
string foo = "foo";
// etc. etc.
How would you grab if-block's parameters and contents from it? The if-block has format of:
if<whitespace>(<parameters>)<whitespace>{<contents>}<anything>
I tried using String.split()
with regex pattern of ^if\s*\(|\)\s*\{|\}\s*
but this fails miserably. Namely, the problem is that ) {
is found also in inner if-block and the closing }
is found from many places as well. I don't think neither lazy or eager expansion works here.
So... any pointers to what might I need here in order to implement this with regex?
I also need to get the remaining string without the if-block's code (so code starting from else { ...
). Using just String.split()
seems to make it difficult as there is no information about the length of the parts that were parsed away.
I initially created a loop based solution (using String.substring()
heavily) for this, but it's dull. I would like to have something fancier instead. Should I go with regex or create a custom, generic function (there are many other cases than just this) that takes the parseable String and the pattern instead (consider the if<whitespace>(...
pattern above)?
Edit: Changed returns to variable assignments as it would have not made sense otherwise.
