提取出0362-2436  39  1     E20 就是等号和连接号&之间的数字，我现在发现，有的中间有E或e出现。有的还有x出现0148-396X 有没有这么写的，=开头 &或者回车符结尾，取这两者之间的字符？

虽然繁琐,但是应该比2楼的方式可靠,如果是读取网页内容的话.

#include<array.au3>
Local $Str = _
                "http://meta.wkhealth.com/pt/pt-core/template-journal/lwwgateway/media/landingpage.htm?" & _
                                "issn=0362-2436&volume=39&issue=1&spage=E20" & @CRLF & _
                "http://meta.wkhealth.com/pt/pt-core/template-journal/lwwgateway/media/landingpage.htm?" & _
                                "issn=1049-2275&volume=24&issue=3&spage=1053" & @CRLF & _ 
                                "http://meta.wkhealth.com/pt/pt-core/template-journal/lwwgateway/media/landingpage.htm?" & _
                                "issn=0148-396X&volume=69&issue=5&spage=E1152" 
Local $sRE = StringRegExp($Str, '(?i)(?:issn=|volume=|issue=|spage=)([\deXx-]+)', 3)
If Not @error Then _ArrayDisplay($sRE)
