If the content in the XML file is
\\([0-9]{13,}+\\)
to represent this in a Java String, you need to code
String target = "\\\\([0-9]{13,}+\\\\)";
The backslash (\) is an escape prefix in Java. So to get a single backslash, you need to specify 2 of them. Since you want two backslashes in the string, you need to specify 4 of them.

And conversely, if your Java code saysString r = "\\([0-9]{13,}+\\)";then the actual value of the string is\([0-9]{13,}+\)and that's what you should put in your XML.
