What is the children method in Mojo::DOM?

Overview

The children method gets all child elements for the given element. This method is provided by the Mojo::DOM module— an HTML/XML DOM parser with CSS selectors.

Syntax

$dom->children

Return Value

This method will return the Mojo::Collection, which contains the Mojo::DOM objects.

Example

The given HTML is as follows:

<div>
   Inside div 
   <p id="a">Inside first paragraph </p>
   <p id="b">Inside second paragraph</p>
</div>

If we get the children for the given HTML using the children method, the output will be as follows:

div

Code

use 5.010;
use Mojo::DOM;
# Parse the html
my $dom = Mojo::DOM->new('<div>Inside div <p id="a">Inside first paragraph </p><p id="b">Inside second paragraph</p></div>');
# Get children
say $dom->children->map('tag')->join("\n");
print "Children for div element \n";
#Get children for specific element
say $dom->at('div')->children->map('tag')->join("\n");

Explanation

  • Line 2: We import the Mojo::DOM module.
  • Line 5: We parse the HTML and store it in the scalar ＄dom.
  • Line 8: We get the children for the given HTML.
  • Line 12: We get the children for the given HTML element div using the children method. Then, we print them.
