Java Regex

[Vincent Tomas]

Hello everyone,

I am new at regex and I have read several tutorials but I still can't find my answer, which is, is there a way to parse using 2 different patterns?

For example,

  
String firstPattern = "some regular expression";
String secondPattern = "another regular expression";
 
Pattern pattern = Pattern.compile(firstPattern);
 
...
...
File parsedFile = new File(cppFileName);
BufferedReader br = new BufferedReader(new FileReader(parsedFile));
 while((line=br.readLine()) != null){
   Matcher matcher = pattern.matcher(line);
   if(matcher.find()){
      // do something
   }
 }
...
...

Sorry for being vague. To explain it in sentences, I am parsing source (.*cpp) files and I am trying to find the following:

variable1->Publish(var1,var2,var3);

Sounds easy, however, some source files have it like the following:

class1::variable1->Publish(variable1, 
                           variable2,
                           variable3);

Is there anyway that I could search on two patterns?

Thank you for any help.

You can build a pattern from 2 patterns using the logical OR operator.

X|Y means match either X or Y, and if you use groups...

"(some regular expression)|(another regular expression)" will match either expression.

My gosh. How did I missed that? Thanks Henry!
