XPath testing that string ends with substring?

Question

Given that the HTML contains:

  <div tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination" class="panel panel-default"></div>

How do we write the following expression in XPath:

Find a <div> element whose tagname attribute ends with the string 'Destination'

I've been searching for days and I can't come up with something that works. Among many, I tried for example:

div[contains(@tagname, 'Destination')]

Answer 1

XPath 2.0

//div[ends-with(@tagname, 'Destination')]

XPath 1.0

//div[substring(@tagname, string-length(@tagname) 
                          - string-length('Destination') + 1)  = 'Destination']

Answer 2

XPath 2 or 3: There's always regex.

.//div[matches(@tagname,".*_Destination$")]

Answer 3

You can use ends-with (Xpath 2.0)

//div[ends-with(@tagname, 'Destination')]

Answer 4

You could use the below xpath which will work with Xpath 1.0

//div[string-length(substring-before(@tagname, 'Destination')) >= 0 and string-length(substring-after(@tagname, 'Destination')) = 0 and contains(@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

Test input :

<root>
<!--Ends with Destination-->
<div tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination" class="panel panel-default"></div>
<!--just Destination-->
<div tagname="Destination" class="panel panel-default"></div>
<!--Contains Destination-->
<div tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination_some_text" class="panel panel-default"></div>
<!--Doesn't contain destination-->
<div tagname="779853cd-355b-4242-8399-dc15f95b3276" class="panel panel-default"></div>
</root>

Test output:

<div class="panel panel-default"
     tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination"/>
<div class="panel panel-default" tagname="Destination"/>

Answer 5

Another solution that is XPath 1.0 compatible:

//div[contains(concat(@tagname, 'UNIQUE'), concat('Destination', 'UNIQUE'))]

I used this while searching for entries in a KeePass Database using the XPath expression search feature:

//Entry/String[contains(concat(Key, 'UNIQUE'), '/UNIQUE')]

found all entries that have a custom string field that ends in '/'.

Answer 6

Incase you have landed on this discussion for a selenium or selenium-webdriver based solution, Selenium still supports only xpath-1.0 where ends-with() isn't supported.

Solution

Given the HTML:

<div tagname="779853cd-355b-4242-8399-dc15f95b3276_Destination" class="panel panel-default"></div>

Using Selenium a potential solution would be to use the contains() method as follows:

//div[contains(@tagname, 'Destination')]

Accomodating the class attributes:

//div[contains(@tagname, 'Destination') and @class='panel panel-default']
