regexvalidator.java

这个是使用java开发的一个平台

package com.exp.web.util.validator;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import com.exp.fcl.xml.EXPXMLNode;
import com.exp.web.util.FormBean;

        if (temp.equals("true")) {
            this.bCaseInsensitive = true;
        }
    }
