Multiple greps for extracting portions of multiple files

I have two greps that are working for extracting portions of multiple files. Can I combine the greps so the extraction pulls two phrases from the files and combines them as one extraction?

Hi Kim,

If you could provide some sample text, grep patterns and expected results, it would be easier to answer your question.

Meanwhile this pattern may help:

Find: (?s)(?P<HEAD>first_pattern|second_pattern).*?(?P<TAIL>first_pattern|second_pattern)

Replace: \P<HEAD>, \P<TAIL>

Sample.txt

--

first_pattern bla bla bla second_pattern

second_pattern foo

bar first_pattern

first_pattern foo bar fizz first_pattern

--

Extracted result:

--

first_pattern, second_pattern

second_pattern, first_pattern

first_pattern, first_pattern

--

I think I understand but I'm not sure how to translate that to my problem.

Here is a sample of the text:

<div class="field--label">Artist</div>

<div class="field--item"><a href="../../collection-artist/alfred-leslie.html" hreflang="en">Alfred Leslie</a></div>

</div>

<div class="field--label">Date of Birth</div>

</div>

</div>

The three grep patterns are:

(?<=Artist</div>
<div class="field--item">)(.*)(?=</a></div>)

(?<=Date of Birth</div>
<div class="field--item">)(.*)(?=</div>)

(?<=Date</div>
<div class="field--item">)(.*)(?=</div>)

The current results are working well independently (the text in blue) - but I'd like them to be returned in sequence (together) with a tilda separating them:

result A ~ result B ~ result C

Try this pattern:

(?s)>Artist</div>\s*<div class="field--item"><a[^>]+>(.*?)</a></div>.+?>Date of Birth</div>\s*<div class="field--item">(.*?)</div>.+?>Date</div>\s*<div class="field--item">(.*?)</div>
