Hello Friends ,
In this post I am presenting how to convert Xpath to CSS Selectors.

HTML CODE:

<html>
<body>
<div>
<a id="a1" class="c1" name="n1">Sample text</a>
</div>
<div>Hello</div>
</body>
</html>

1- select link having id="a1" using Absolute XPath

XPath - /html/body/div/a[@id='a1']
CSS Selector- html>body>div>a[id='a1']

2- select link having id="a1" using Relative XPath

XPath - //a[@id='a1']
CSS Selector- a[id='a1']

XPath - //html //a[@id='a1']
CSS Selector- html a[id='a1']

3- Select All links in webpage:

XPath - //a
CSS Selector- a

4-Select all first link in webpage:

XPath - //a[1]
CSS Selector- a:nth-of-type(1)

5-Select first link out of all links using group index

XPath - ( //a)[1]
CSS Selector- css does not support group index

6- Select link by attribute ID

XPath - //a[@id='a1']
CSS Selector- a#a1

7- Select link by attribute Class Name

XPath - //a[@class='c1']
CSS Selector- a.c1

8- Select link by attribute Name

XPath - //a[@name='n1']
CSS Selector- a[name="n1"]

9-Select link by using text()

XPath - //a[text()='Sample text']
CSS Selector- css does not support text.

10-Select link by using AND Operation

XPath - //a[@id="a1 and @name='n1']
CSS Selector- a[id="a1"][name='n1']

11-Select link by using OR Operation

XPath - //a[@id="a1 or @name='n1']
CSS Selector- a[id="a1"],[name='n1']

12-Select link by using NOT (should select the link other than a1)

XPath - //a[not(@id='a1')]
CSS Selector- a:not(id='a1')

13-Select link using contains

XPath - //a[contains(@id,'a1')]
CSS Selector- a[id *= 'a1']

14-Select parent of link having id='a1'

XPath - //a/parent::div
CSS Selector- div:has[>a]

15- Select parent of link having id='a1' using shortcut

XPath - //a/..
CSS Selector- div:has[>a]

16- Select ancestor of link having id='a1'

XPath - //a/ancestor::body
CSS Selector- body:has[ a]

17-Select following sibling of div Tag

XPath - //div/following-sibling::div
CSS Selector- div + div
