Java Utililty Methods XML Sanitize

String sanitizeJson4XML(String jsonString)
sanitizeJson4XML - Sanitize a JSON string so it converts to XML without error.

jsonString = jsonString.trim();
if (!jsonString.startsWith("{")) {
 jsonString = "{\"Anonymous\":" + jsonString + "}";
return jsonString;

String sanitizeXML(String xml)
Remove all unnecessary white spaces, tabs and line breaks from XML string.

return xml.replace("\n", "").replace("\r", "").replace("\t", "").replaceAll(">\\s+<", "><").trim();

String SanitizeXmlString(String xml)
Sanitize Xml String

if (xml == null || xml.isEmpty()) {
 return xml;
StringBuilder buffer = new StringBuilder(xml.length());
for (int i = 0; i < xml.length(); i++) {
 if (IsLegalXmlChar(xml.charAt(i))) {
 buffer.append(xml.charAt(i));
return buffer.toString();

String sanitizeXmlTypeName(String name)
Since XML names can not contain all characters JSON names can, we may need to replace characters.

StringBuilder sb;
int changes = 0;
if (name.endsWith("[]")) {
 do {
 name = name.substring(0, name.length() - 2);
 ++changes;
 } while (name.endsWith("[]"));
 sb = new StringBuilder(name);
