What is the content method in Mojo::DOM?
Share
Overview
The content method gets the content for a given element or replaces the content present in the same element. This method is provided by the Mojo::DOM module, which is an HTML/XML DOM parser with CSS selectors.
Syntax
We use the following syntax to get the content:
$dom->at('html element')->content
We use the following syntax to replace the content:
$dom->at('html element')->content('new content')
Return values
content: This method returns the given node's content.content('new content'): This method returns theMojo::DOMobject after replacing the content with new content.
Let’s take a look at an example.
Example
A sample HTML code is given below.
<div>Inside div<p id="a"><span>Inside first paragraph</span> </p><p id="b">Inside second paragraph</p></div>
If we try to get the content for the span element using the content method, we get the following output:
Inside first paragraph
Code
use 5.010;use Mojo::DOM;# Parse the HTMLmy $dom = Mojo::DOM->new('<div>Inside div <p id="a"><span>Inside first paragraph</span></p><p id="b">Inside second paragraph</p></div>');# Get the contentsay $dom->at('span')->content
Explanation
- Line 2: We import the
Mojo::DOMmodule. - Line 5: We parse the HTML and store it in the scalar
$dom. - Line 8: We print the content for the given element
spanusing thecontentmethod.
Let's now take a look at how to replace the content for the given element.
Code
use 5.010;use Mojo::DOM;# Parse the HTMLmy $dom = Mojo::DOM->new('<div>Inside div <p id="a"><span>Inside first paragraph</span></p><p id="b">Inside second paragraph</p></div>');# Replace the contentsay $dom->at('div')->content("Replaced content in div")
Explanation
- Line 8: We replace the content for the
divelement, and print theMojo::DOMobject with the new content.
