Notepad++ find value with regex and replace to value that find with another regex

Question

i have a string:

...some values...<id1>10052023</id1>...some others...<id2>306689461795</id2>...

i need to replace value between id1 with value from id2, is it possible to do with npp?

i know about groups but i don't know how to use it properly in this case.

my value can be found and stored in group 1 with regex like this:

^.*<id1>(.*)</id1>.*$

am i right?

Answer 1

With xmlstarlet (available on all platforms):

$ cat file
<root>
...some values...<id1>10052023</id1>...some others...<id2>306689461795</id2>...
</root>

$ xmlstarlet edit -d '//id1/text()' -u '//id1' -x '//id2/text()' file
<?xml version="1.0"?>
<root>
...some values...<id1>306689461795</id1>...some others...<id2>306689461795</id2>...
</root>
