Trim URL到Excel的ROOT / SUBDOMAIN

Question

我需要将Microsoft Excel中的URL修剪到根域和子域。

A1 =包含https://blog.example.com/page/B1 =应产生example.comC1 =应该产生blog.example.com

两个删除http，https，.www和PATH的公式。第一个版本（B1）也应删除SUBDOMAIN。

我现在只有一个公式：

=MID(SUBSTITUTE(A2;"www.";"");SEARCH(":";A2)+3;SEARCH("/";SUBSTITUTE(A2;"www.";"");9)-SEARCH(":";A2)-3)

https://example.com/page/page产生example.comhttp://www.example.com/page/page产生example.comhttp://blog.example.com/page/产生blog.example.comexample.com/page产生#VALUE!www.example.com/page产生#VALUE!

您可以在上面的示例中看到，我得到了很好的结果。但是，如果没有http或https，它就无法工作。此版本还保留子域。

Answer 1

在B1中尝试一下，

=SUBSTITUTE(TRIM(RIGHT(SUBSTITUTE(REPLACE(REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/", FIND("/", REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/"), LEN(A1), TEXT(,)), CHAR(46), REPT(CHAR(32), LEN(A1))), LEN(A1)*2)), CHAR(32), CHAR(46))

....和C1中的这个，

=SUBSTITUTE(REPLACE(REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/", FIND("/", REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/"), LEN(A1), TEXT(,)), "www.", TEXT(,))

Answer 2

Subdomain-它是Jeeped's answer，但是我添加了对空白单元格的支持，因为原始版本输出的是“ /”：

=IF(ISBLANK(A1), "", SUBSTITUTE(REPLACE(REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/", FIND("/", REPLACE(A1, 1, IFERROR(FIND("//", A1)+1, 0), TEXT(,))&"/"), LEN(A1), TEXT(,)), "www.", TEXT(,)))

Domain-支持国际域（例如this.co.uk）的版本from MrExcel。但是与吉普车的版本不同，它不支持www.this.co或test.this.co之类的1字TLD-有人知道如何解决此问题吗？现在，我至少在“ www”中使用帮助行：

=IF(LEFT(a1,LEN("www."))="www.",RIGHT(a1,LEN(a1)-LEN("www.")), a1)
=SUBSTITUTE(TRIM(RIGHT(SUBSTITUTE(TRIM(TRIM(LEFT(SUBSTITUTE(TRIM(IFERROR(MID(b1,FIND("://",b1)+3,99),b1))&"/","/",REPT(" ",99)),99))),".",REPT(" ",99)),99*(2+(LEN(TRIM(RIGHT(SUBSTITUTE(TRIM(TRIM(LEFT(SUBSTITUTE(TRIM(IFERROR(MID(b1,FIND("://",b1)+3,99),b1))&"/","/",REPT(" ",99)),99)))&".",".",REPT(" ",99)),198)))=2))))," ",".")

它工作于：

            A                   |           B           |       C
(blank)                         |   ""                  |   ""

Answer 3

如果您的excel版本具有FILTERXML函数（可以在Excel 365, Excel 2019, Excel 2016, and Excel 2013中找到），

假设您的网址在A2:A29范围内

要查找子域，请在单元格B2中输入以下公式并将其向下拖动：

=SUBSTITUTE(FILTERXML("<t><s>"&SUBSTITUTE(IFERROR(MID(A2,FIND("//",A2)+2,LEN(A2)),A2),"/","</s><s>")&"</s></t>","t/s[1]"),"www.","")

有关此公式背后的逻辑，您可以阅读本文：Extract Words with FILTERXML。

要找到根域，请在单元格C2中输入以下公式并将其向下拖动：

=IF((SUMPRODUCT(--(MID(B2,ROW($1:$100),1)="."))-IF(SUMPRODUCT(--(MID(RIGHT(B2,8),ROW($1:$8),1)="."))=3,2,SUMPRODUCT(--(MID(RIGHT(B2,8),ROW($1:$8),1)="."))))>0,RIGHT(B2,LEN(B2)-FIND(".",B2)),B2)

我使用第一个公式中的Sub Domain来找到Root Domain。技巧是找出第一个点.之前的URL的组成部分是根域还是子域，并采取相应的措施。
