Absolute Xpath: It uses Complete path from the Root Element to the desire element. 

Relative Xpath: You can simply start by referencing the element you want and go from there. 

Relative Xpaths are always preferred as they are not the complete paths from the root element. (//html//body). Because in future, if any webelement is added/removed, then the absolute Xpath changes. So Always use Relative Xpaths in your Automation.

An absolute xpath in HTML DOM starts with /html e.g.

<pre><code>/html/body/div[5]/div[2]/div/div[2]/div[2]/h2[1]
</code></pre>

and a relative xpath finds the closed id to the dom element and generates xpath starting from that element e.g. 

<pre><code>.//*[@id='answers']/h2[1]/a[1]
</code></pre>

You can use firepath (firebug) for generating both types of xpaths

It won't make any difference which xpath you use in selenium, the former may be faster than the later one (but it won't be observable)

Absolute xpaths are prone to more regression as slight change in DOM makes them invalid or refer to a wrong element

++<body>

</html>|code-block|syntax|javascript|3927878|所以输入输入相对路径=//*@id=“用户名”|offset|length|style|BOLD|3927879|绝对xpath的缺点是维护性很高，如果在html中没有做任何更改，它可能会干扰整个路径，而且有时我们需要写很长的绝对xpath，所以相对xpath是首选的。|3927880|entityMap^0|0|0|A|D|0|0|26|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|V|8|@$I|W|J|X|K|L]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

Consider Below Html

<pre><code>&lt;html&gt;
 &lt;body&gt;
 &lt;input type ="text" id="username"&gt;
 &lt;/body&gt;

&lt;/html&gt;
</code></pre>

so Absoulte path= html/body/input
and Relative path = //*[@id="username"]

Disadvantage with Absolute xpath is maintenance is high if there is nay change made in html it may disturb the entire path and also sometime we need to write long absolute xpaths so relative xpaths are preferred

blocks|key|3927937|text|我们可以说主要有三点不同：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3927938|在绝对路径中不使用//|offset|length|style|CODE|3927939|Attributes在绝对路径中使用as属性在relative|unordered-list-item|3927940|
|3927941|Absolute中使用as+|3927942|3927943|是完整路径其中as相对是部分路径|3927944|3927945|主要是相对的，绝对不是首选的，因为它是一个完整的路径，元素可能会因为动态的性质而改变，所以可能会有路径的中断，所以相对是首选的。|3927946|entityMap^0|0|9|2|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@$D|Y|E|Z|F|G]]|9|@]|A|$]]|$1|H|3|I|5|J|7|10|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|11|8|@]|9|@]|A|$]]|$1|M|3|N|5|J|7|12|8|@]|9|@]|A|$]]|$1|O|3|L|5|6|7|13|8|@]|9|@]|A|$]]|$1|P|3|Q|5|J|7|14|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|15|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|16|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|17|8|@]|9|@]|A|$]]]|V|$]]

We can say mainly there are 3 differences:
<ol>
<li>Absolute will start with <code>/</code> where as Relative will start with <code>//</code></li>
<li>Attributes is not used in absolute where as attribute is used in relative</li>
<li>Absolute is a complete path where as relative is partial path</li>
</ol>
Mainly Relative is preferred, Absolute is not preferred because since its a complete path and elements can change because of dynamic nature so there may be breakage of path so relative is preferred.

blocks|key|5345514|text|绝对XPath:这是查找元素的直接方法，但绝对XPath的缺点是，如果在元素的路径中进行了任何更改，则XPath将失败。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|5345515|XPath的关键特征是它以单个正斜杠(/)开头，这意味着您可以从根节点选择元素。|5345516|下面是绝对xpath的示例。|5345517|/html/body/div[1]/section/div/div[2]/div/form/div[2]/input[3]|code-block|syntax|javascript|5345518|相对Xpath:相对Xpath从HTML+DOM结构的中间开始。它以双正斜杠(//)开头。它可以在网页上的任何地方搜索元素，这意味着不需要编写很长的xpath，您可以从HTML+DOM结构的中间开始。相对Xpath总是首选的，因为它不是根元素的完整路径。|5345519|下面是一个相对XPath的例子。|5345520|//input[@name=’email’]|5345521|entityMap^0|0|8|0|0|0|0|0|8|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Z|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|10|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|11|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|12|8|@$9|13|A|14|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|15|8|@]|D|@]|E|$]]|$1|S|3|T|5|L|7|16|8|@]|D|@]|E|$M|N]]|$1|U|3|-4|5|6|7|17|8|@]|D|@]|E|$]]]|V|$]]

Absolute XPath:
It is the direct way to find the element, but the disadvantage of the absolute XPath is that if there are any changes made in the path of the element then that XPath gets failed.
The key characteristic of XPath is that it begins with the single forward slash(/) ,which means you can select the element from the root node.
Below is the example of an absolute xpath.
<pre><code>/html/body/div[1]/section/div/div[2]/div/form/div[2]/input[3]
</code></pre>
Relative Xpath:
Relative Xpath starts from the middle of HTML DOM structure. It starts with double forward slash (//). It can search elements anywhere on the webpage, means no need to write a long xpath and you can start from the middle of HTML DOM structure. Relative Xpath is always preferred as it is not a complete path from the root element.
Below is the example of a relative XPath.
<pre><code>//input[@name=’email’]
</code></pre>
