意外的空匹配组值
Unexpectedly empty match-group value
我正在使用正则表达式来抓取网页内容。我对另一张表使用了类似的方法，效果很好；但我对此有疑问
.Giocatore_ammonito = Regex.Match(Content, "<td class=""player large-link""\s*>(.+?)</td>").Groups(1).ToString
Groups(1).ToString returns 一个空白的结果，但我不明白为什么。
我缺少的正则表达式有什么问题？

概述
继续@Rawing 开始处理他的评论的方向，正则表达式需要考虑的内容中存在反斜杠转义问题。
试试这个...
.Giocatore_ammonito = Regex.Match(Content, "<td class=\""player large-link\""\s*>(.+?)<\/td>").Groups(1).ToString
' ^^ ^^ ^^
...考虑 class 属性值周围双引号前面的反斜杠 和 td 中正斜杠前面的反斜杠结束标签。
另外，您可能希望清除反斜杠转义，否则它将保留在匹配组值中。
演示代码
这里是 VB.NET 代码，显示 1) 更新后的正则表达式如何处理您的内容以及 2) 如何可选地清除从匹配组值中转义的挥之不去的反斜杠：

概述
继续@Rawing 开始处理他的评论的方向，正则表达式需要考虑的内容中存在反斜杠转义问题。
试试这个...
.Giocatore_ammonito = Regex.Match(Content, "<td class=\""player large-link\""\s*>(.+?)<\/td>").Groups(1).ToString
' ^^ ^^ ^^
...考虑 class 属性值周围双引号前面的反斜杠 和 td 中正斜杠前面的反斜杠结束标签。
另外，您可能希望清除反斜杠转义，否则它将保留在匹配组值中。
演示代码
这里是 VB.NET 代码，显示 1) 更新后的正则表达式如何处理您的内容以及 2) 如何可选地清除从匹配组值中转义的挥之不去的反斜杠：
