Question

我不知道为什么这只适用于最后审理,而不是像我所期望的那样。感谢任何帮助。

www.un.org/Depts/DGACM/index_spanish.htm Input string:

<a href="http://www.scirra.com" target="_blank" rel="nofollow">http://www.scirra.com</a><br /><br />
<a href="http://www.scirra.com" target="_blank" rel="nofollow">http://www.scirra.com</a><br /><hr>

Regex:

 SEO scirra links
Dim regEx
Set regEx = New RegExp

  BB code urls
With regEx
    .Pattern = "<a href=""http://www.scirra.com([^]]+)"" target=""_blank"" rel=""nofollow"">"
    .IgnoreCase = True
    .Global = True
    .MultiLine = True
End With
strMessage = regEx.Replace(strMessage, "<a href=""http://www.scirra.com$1"" target=""_blank"" title=""Some value insert here"">")

set regEx = nothing

<<>Output>:

<a href="http://www.scirra.com" target="_blank" rel="nofollow">http://www.scirra.com</a><br /><br />
<a href="http://www.scirra.com" target="_blank" title="Some value insert here">http://www.scirra.com</a><br /><hr>

Can anyone shed light on why it s only adding the title to the last found instance? (I ve tested with more, always just applies to last one)

Answer 1

其原因是:

...a.com-->([^]]+)<--

您在投入中一劳永逸地尝试与并非“<代码>>的的所有内容相匹配。由于在您的投入中根本没有>,因此它吞 everything了一切(即,甚至新线),但必须背后,才能满足您的其余部分,这意味着它可追溯到last> Target=_blank”......。

如果你想要取代<条码>rel=“nofollow”,并允许在<条码>后面的任何途径:http://www.scirra.com,则你可以使用这一条码:

(<a href="http://www.scirra.com((/[^/"]+)*/?)" target="_blank" )rel="nofollow">

改为:

$1title="Some value insert here">

现行法规:

Dim regEx
Set regEx = New RegExp

  BB code urls
With regEx
    .Pattern = "(<a href=""http://www.scirra.com((/[^""/]+)*/?)"" target=""_blank"" )rel=""nofollow"">"
    .IgnoreCase = True
    .Global = True
    .MultiLine = True
End With
strMessage = regEx.Replace(strMessage, "$1title=""Some value insert here"">")

但请注意,这在所替换的URLs中具有很大的限制性。例如,目标内容是否可能有其他内容,或有更多的属性?
