for (int i = 0; i < charArray.length; i++) {
 final char ch = charArray[i];
 switch (cdataFilter(ch)) {
 case 0:
 buffer.append(ch);
 break;

text = text.replaceAll("\t", " ");
final int len = text.length();
final StringBuilder result = new StringBuilder(len);
char myChar;
for (int i = 0; i < len; ++i) {

String unwrapCdata(String s)
unwrap Cdata

return (s.startsWith("<![CDATA[") && s.endsWith("]]>")
 ? s.substring(9, s.length() - 3).replace("]]]]><![CDATA[>", "]]>")
 : s);

String unwrapCdata(String sText)
If the text is wrapped with a "[CDATA[ ]]" tag then it is removed and the text inside is returned.

if ((sText != null) && (sText.trim().startsWith("[CDATA[")) && (sText.trim().endsWith("]]"))) {
 return sText.trim().substring(7, sText.trim().length() - 2);
} else {
 return sText;
