How to locate an element which have same name and same atrributes in selenium, Selenium Notes, Examples, Videos, By.www.laxmiroy.blogspot.com/
Automation using selenium is a great experience. It provides many way to identif an object or element on the web page.
But sometime we face the problems of idenfying the objects on a page which have same attributes. When we get more than
one element which are same in attribute and name like multiple checkboxes with same name and same id. More than one button having
same name and ids. There are no way to distingues those element. In this case we have problem to instruct selenium to identify a perticular
object on a web page.
I am giving you a simple example . In the below html source there are 6 checkboxes are there having same type and same name.
It is really tough to select third or fifth.
<html>
<body>
<input type='checkbox' name='chk'>first
<br><input type='checkbox' name='chk'>second
<br><input type='checkbox' name='chk'>third
<br><input type='checkbox' name='chk'>forth
<br><input type='checkbox' name='chk'>fifth
<br><input type='checkbox' name='chk'>sixth
</body>
</html>
Thare are some function we can use in Xpath to identify the abject in above cases.
An XPath expression can return one of four basic XPath data types:
* String
* Number
* Boolean
* Node-set
XPath Type : Functions
Node set : last(), position(), count(), id(), local-name(), namespace-uri(), name()
String : string(), concat(), starts-with(), contains(), substring-before(), substring-after(), substring(), string-length(), normalize-space(), translate()
Boolean : boolean(), not(), true(), false(), lang()
Number : number(), sum(), floor(), ceiling(), round()
I will show you how we can use some of these above functions in xpath to identify the objects.
Node Set : last()
In the above html file there are six checkboxes and all are having same attributes (same type and name)
How we can select the last checkbox based on the position. We can use last() function to indentify the last object among all similar objects.
Below code will check or uncheck the last checkbox.
selenium.click("xpath=(//input[@type='checkbox'])[last()]");
The example which you gave above, is for the last check box only what if one want to select the 3rd or 5th checkbox out of 10checkboxes?
