Usage

From source file:com.netspective.commons.text.TextUtils.java

/**
 * Given a text string, return a string that would be suitable for that string to be used
 * as a Java constant (public static final XXX). The rule is to basically take every letter
 * or digit and return it in uppercase and every non-letter or non-digit as an underscore.
 * This trims all non-letter/digit characters from the beginning of the string.
 *//*from   w w w  .  ja va 2  s . c o  m*/
public String xmlTextToJavaConstantTrimmed(String xml) {
    if (xml == null || xml.length() == 0)
        return xml;

    boolean stringStarted = false;
