Given that the HTML contains:
鉴于HTML包含:
<div tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination" class="panel panel-default"></div>
How do we write the following expression in XPath:
我们如何在XPath中编写以下表达式:
Find a <div>
element whose tagname
attribute ends with the string 'Destination'
找到一个
I've been searching for days and I can't come up with something that works. Among many, I tried for example:
我一直在寻找几天,我无法想出一些有用的东西。在众多中,我试过例如:
div[contains(@tagname, 'Destination')]
4 个解决方案

XPath 2.0
//div[ends-with(@tagname, 'Destination')]
XPath 1.0
//div[substring(@tagname,string-length(@tagname) -string-length('Destination') +1)
= 'Destination']
#2

XPath 2 or 3: There's always regex.
XPath 2或3:总是正则表达式。
.//div[matches(@tagname,".*_Destination$")]
#3

You can use ends-with
(Xpath 2.0)
你可以使用ends-with(Xpath 2.0)
//div[ends-with(@tagname, 'Destination')]
#4

You could use the below xpath which will work with Xpath 1.0
您可以使用下面的xpath,它将与Xpath 1.0一起使用
//div[string-length(substring-before(@tagname, 'Destination')) >= 0 and string-length(substring-after(@tagname, 'Destination')) = 0 and contains(@tagname, 'Destination')]
// div [string-length(substring-before(@ pentame,'Destination'))> = 0和string-length(substring-after(@ pentame,'Destination'))= 0并包含(@tagname,'Destination “)]
Basically it checks if there is any string ( or no strings ) before the first occurrence of Destination
but there should not be any text after the Destination
基本上它会在第一次出现Destination之前检查是否有任何字符串(或没有字符串),但是在Destination之后不应该有任何文本
