For that, let us use the following logic. If you want to replace multiple characters with a single character you can review the information on POSIX using meta characters, Įxample: I want to remove all characters that are not Alpha (A-Z, a-z) or Numeric (0-9) within a string field. String str 'The Walking Dead' We want to replace the substring Dead with Alive. #out_proc = proc_data_repl.replaceAll(out_keyw,out_repl_magic) So just use this code: String replaced string. You don't really need a regex here, just a simple call to Stringreplace(String) will do the job. Since the string is immutable, the original string remains. Out_repl_magic = " " + replace + "^3B" Strings in Java are immutable to so you need to store return value of thereplace method call in another String. Java String replace() method is used to replace part of the string and create a new string object. out_repl_magic will be The "^3B" is the hex used for the semicolon. These rules build the variables in the correct format needed for the replaceAll. Select xpathresult into replace from processdata where xpath = "/ProcessData/replace" Select xpathresult into keyword from processdata where xpath = "/ProcessData/keyword" These select rules will pull the data from xpath and store them into the correct variables. If you cannot have the assigns as listed in #3, this rule will need to be used. #PROC_DATA = ob.replaceAll(keyword,replace) Then use the rule format above (that is, by declaring the variable ob as an object in the Extended Rule, assigning a value to ob, and writing ob's new value back to the #PROC_DATA field: Select xpathresult into replace from processdata where xpath = "string(/ProcessData/replace)" Select xpathresult into keyword from processdata where xpath = "string(/ProcessData/keyword)" You would then use the select from process data extended rules to move the values into the variables (keyword and replace) In this post, we are going to replace a substring in a String in Java. You actually have to use the XML release format of ** where the ** is the two character hex value of the literal value you want to replace. For the hex example, you must first place the character hex values into process data through an assign service. Again, you can use the literal value or the hex value. Literally specifying the characters to As the hex value of each keyword or replacementģ. The variables keyword and replace normally will be writtenġ. #PROC_DATA = ob.replaceAll(keyword,replacement) Write a Java program to replace each substring of a given string that matches the given regular expression with the given replacement. Here we assign the contents of the data field #PROC_DATA To call the function, you must first declare a variable of type object in your Extended Rule: This replaces cumbersome extended rules to parse through each character of the string looking for the character to replace. You can call the () function in a User Exit in an Extended Rule in a map to replace all occurrences of a character (or characters) in a string field. Yes, but you will need to utilize techniques outside the normal mapping functions.
