I have xml files to replace info between tags . It works when my xml file have body like this:

<VARIABLES>test</VARIABLES>

Problem starts when it is like that:

<VARIABLES>test
test
test
</VARIABLES>

My pattern didn't see it at all:

string newText = Regex.Replace(content, "(?<=<VARIABLES>).+?(?=</VARIABLES>)", replaceWithText);

The problems seem to be just starting if you parse XML with regex. However, this immediate issue is easy to solve with `RegexOptions.Singleline` option. – Wiktor Stribiżew Feb 26 '19 at 13:13

I have one more question, how make pattern to search exactly xml TAG like `` but dont include ``. My pattern: `"(?<=).+?(?=" + searchText +">)"` – fosfik Feb 28 '19 at 07:30
No idea what you mean. – Wiktor Stribiżew Feb 28 '19 at 07:38
Example: `searchText` = test. In my xml files theres tags like `` and `` or ``. My pattern search it in whole xml and it says that it find 3 test tags, it shoudl be only 1 because only the 1st is exactly what I search. – fosfik Feb 28 '19 at 07:42
