Replacing Substring in Java

Question

I have situation in Java where I am reading contents of file in String. It is something like this -

String S = "<name>source</name> <value>NB_System</value> </nameValue> <nameValue> <name>timestamp</name> <value>2015-6-25 22:39:41:455</value> </nameValue> <nameValue> <name>TTL</name> <value>0</value> </nameValue>"

I want to delete the timestamp from the string - timestamp</name> <value>2015-6-25 22:39:41:455</value>

Timestamp is creating issues in comparing results with master copy. How to get rid of timestamp here?

... parse, find indexes and then call `String.substring(...)`? What code have you tried? — Jashaszun, Jun 25 '15 at 23:09
Your text looks like XML. Why don't you use XML parser and remove nodes or their content you don't want? Also [regex is not best tool to parse XML](http://stackoverflow.com/q/701166/1393766). — Pshemo, Jun 25 '15 at 23:24

If you want to get rid of the tag timestamp with its value, you can use a code like this:

S = S.replaceAll("<name>timestamp.*?<\/value>", "");

On the other hand, if you just want to get rid of the value tag for the timestamp you could use:

S = S.replaceAll("<name>timestamp.*?<\/value>", "<name>timestamp</name>");

Corrected : S = S.replaceAll("timestamp.*?", ""); – Faiz Ali Jun 26 '15 at 02:05

S = S.replaceAll("<name>timestamp</name>[^<]*<value>[^<]*</value>", "");
