Answer 1

要求,如上图.采集的数据为批量采集,
不能有其他杂七杂八的代码.代码不是很规则,采集有些难度.
需要用正则表达式才能解决这个问题.用(?<content>[\s\S]*?)这个采集.

Answer 2

也不说采集什么，就当你采集流媒体吧
#กรอด</a>\s*<a onClick=PlayAudioFile\('([^']+)'#uiU
#กร่อน</a>\s*<a onClick=PlayAudioFile\('([^']+)'#uiU

Answer 3

preg_match_all('#<tr><td.*>(.*)</td><td.*>(.*)</td><td.*>(.*)</td><td.*>(.*)</td></tr>#isU', $s, $r);

Answer 4

兄弟,请看1楼的说明和2楼的介绍.采集红色框里面的内容!
格式为(?<content>[\s\S]*?)

Answer 5

使用正则匹配内容时必须包含content组来识别内容,格式为(?<content>您的正则)谢谢 

Answer 6

红色部分一条正则比较难，多条或者可以，用xpath倒简单点
