RegEx matches the href and content marked by a in the div.

RegEx matches the href and content marked by a in the div.

 

 

After a long time, I got into touch with regular expressions again. It seems like a similar feeling. Do you have such a feeling? I must have mastered such a small CASE, so I took the time to read the manual, so I understood it, so next time it seems similar ......

 

Write down the places used today:

// Demo

 

$str = '

• Li
• Running shoes and basketball shoes

Tryagin '; // first match DIV preg_match_all ('/(.*?) /I ', $ str, $ matches); if (! Empty ($ matches) {$ target_content = $ matches [0] [0];} // The a mark is matched for the second time. Note () is to return the matched content preg_match_all ('/(. *?) /I ', $ target_content, $ matches_detail); if (! Empty ($ matches_detail) {$ href_content = $ matches_detail [1]; $ detail_content = $ matches_detail [2];}
