get multiple texts between two tags

Question

my string is like this:

<test id="Name_123456789" ba="1"><source>Ai891</source></test><test id="Name_12340506789" ba="2"><source>Ai853491</source></test> <test id="56712340506789" ba="2"><source>Ai853491</source></test>

I want to get the text between <test id="Name and </test> from my string:

final output should be in the List<string> like here:

1._123456789" ba="1"><source>Ai891</source>

2._12340506789" ba="2"><source>Ai853491</source></test>
