URGENT HELP : Java Regular Expression

[asheshrocky]

Hi All,

This is my first post with this forum.
I have a situation where am stuck with the Pattern matcher to compile my regular expression.

I have a formula to be parsed as below :

APDM_ABS_LT_WL-A+WL_BL|APDM_ABS_LT_WL-A+WL_BL|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|1.00E+20|abs(if((x1 = 1 || x1 = 2), y = 0, y=1))

This is my code snippet:

	private void genDisWithCalPara(File calParaFile) {
		ArrayList<String> calParaNameAL = new ArrayList<String>(500);
		ArrayList<String> calPara4LimitDisAL = new ArrayList<String>(500);
		ArrayList<String> calParaFormulaAL = new ArrayList<String>(500);

		try{
			//If the constructor throws an exception, the finally block will NOT execute
	
			BufferedReader reader  = new BufferedReader(new FileReader(calParaFile));
			Pattern pattern = Pattern.compile("(.*)(\\|.*\\|.*\\|.*\\|.*\\|.*\\|.*\\|.*\\|.+\\|)(.*)");
			Matcher matcher = null;

			try{
				String aLine = null;
				while((aLine=reader.readLine()) != null){
	System.out.println(aLine);
					matcher = pattern.matcher(aLine);
					if (matcher.find()){
						System.out.println("g(1)="+matcher.group(1));
						System.out.println("g(2)="+matcher.group(2));
						System.out.println("g(3)="+matcher.group(3));
						calParaNameAL.add(new String(matcher.group(1)));
						calPara4LimitDisAL.add(new String(matcher.group(2)));
						calParaFormulaAL.add(new String(matcher.group(3)));
					}//end if
					continue;
				}//end while
			}finally{
				reader.close();
			}//end finally
		} catch (Exception e){
			JNotify.getInstance().log(JNotify.ERROR,"000"
					, "JCalPara.genDisWithCalPara"
					, "ConfigFileNotFound"
					, JNotify.getStackTraceString(e)
				);
			System.exit(1);
		} //end catch
     try {
		if (calParaNameAL.size() > 0){
			createDatawcalDIS(calParaNameAL,calParaFormulaAL);
			createLimitwcalDIS(calParaNameAL,calPara4LimitDisAL);
		}
     }
     catch (Exception e){
			JNotify.getInstance().log(JNotify.WARN,"000"
					, "JCalPara.genDisWithCalPara"
					, "calParaNameAL is Empty"
					, JNotify.getStackTraceString(e)
				);
     }
			System.exit(1);
	}

Ok now the problem i am facing is that i am not able to get the required result with the currently used Pattern.compile.
Whenever i have an OR (||) symbol in the forumula (if((x1 = 1 || x1 = 2), y = 0, y=1)),it shows me an different result as it read || symbol as pipe(|) and not as logical OR .

When i run above i get the following output:

APDM_ABS_LT_WL-A+WL_BL|APDM_ABS_LT_WL-A+WL_BL|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|1.00E+20|abs(if((x1 = 1 || x1 = 2), y = 0, y=1))
g(1)=APDM_ABS_LT_WL-A+WL_BL|APDM_ABS_LT_WL-A+WL_BL
g(2)=|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|1.00E+20|abs(if((x1 = 1 ||
g(3)= x1 = 2), y = 0, y=1))

Expected Result should be like :

APDM_ABS_LT_WL-A+WL_BL|APDM_ABS_LT_WL-A+WL_BL|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|1.00E+20|abs(if((x1 = 1 || x1 = 2), y = 0, y=1))
g(1)=APDM_ABS_LT_WL-A+WL_BL
g(2)=|APDM_ABS_LT_WL-A+WL_BL|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|-1.00E+20|1.00E+20|1.00E+20|
g(3)=abs(if((x1 = 1 || x1 = 2), y = 0, y=1))

Please help me to achieve the same...

did you find something wrong with my post ?
I just tried to brief my problem.....it would be difficult to just explain in words i guess.
