我希望匹配所有键/值对。喜欢：

"conventional_long_name" => "Italian Republic"

我正在使用的正则表达式是：

preg_match_all("/\|(?:\s+)?([^=]+)(?:\s+)?=(?:\s+)?(.+)/", $line, $matches);

哪个工作正常，但它无法解析这一行：

|latd=41 |latm=54 |latNS=N |longd=12 |longm=29 |longEW=E

我做错了什么？有什么想法吗？

Answer 1

你可以使用这样的东西吗？

\|\s*([^=]+?)\s*=\s*((?:<[^<>]*>|\[\[(?:(?!\]\]).)*\]\]|{{(?:(?!}}).)*}}|[^|{}\[\]<>]+)+)

regex101 demo

如果它们在|或[[ ... ]]或< ... >范围内，它基本上会抓取所有内容（甚至是{{ ... }}），但如果它们与单独的|不符，它不在其中一个括号内。
