http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15461 Word boundry (\b) not matching using org.apache.regexp.RE Summary: Word boundry (\b) not matching using org.apache.regexp.RE Product: Regexp Version: unspecified Platform: PC OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Other AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The word boundry escape \b does not seem to be matching. Using the Jakarta- Regexp-1.2 Binary implementation fails. Perl5 works correctly as a comparison. Simplest Example: Regexp: \b(eek.) Match against: "week" Jakarta returns "true" for a match, while Perl returns "false". Workaround: Instead of \b I've been using (^|\s), but this changes my parenCount for retriving data. Sample JSP: <%@page import="org.apache.regexp.*"%> <% String[] stringList = new String[] { "eekeek", "week", "my eeker", "the meeker" }; String regExp = "\\b(eek.*)"; RE testRE = new RE(regExp); out.write("<PRE>Testing RE Engine for word boundry: (" + regExp + ") \n"); for (int pos = 0; pos < stringList.length; pos ++) { if (testRE.match(stringList[pos])) { int start = testRE.getParenStart(1); int end = testRE.getParenLength(1) + start; out.write("Matched " + stringList[pos].substring(0, start) + "<B><U>" + stringList[pos].substring(start, end) + "</U></B>" + stringList[pos].substring(end) + "\n"); } else { out.write("No Match: " + stringList[pos] + "\n"); } } %> Result: Testing RE Engine for word boundry: (\b(eek.*)) Matched eekeek Matched week Matched my eeker Matched the meeker -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
