Jquery: Parsing HTML

Question

I need help in parsing href tags. Currently, everything is being parsed as text, however I need to parse the links so that I can send it to the php page later using AJAX.

my HTML looks like:

<div id="word_content">
<br>Testing Time: 2015-10-29 17:57:11<br>
    Total Age: 19<br>
    Total Friemd: 9<br>
    Total Family: 10<br>
    <br>
Here are the suggestions  - Him_530037_: <a href="www.mytarget.com="_blank">93358546</a>
<h3>Overview</h3><br>
<ul>
    <li>(The overlap provided is not good)</li>
</ul>

<h3>Structure</h3><br>
<h4>Target:</h4><br>
<ul>
    <li>Audience.</li>
    <li>Lookalike</li>
    <li>Overlap of Audience</li> 
    <a href="https://www.myPage.com/lolPagess/?id=06" target="_blank">06<font name="names" hidden="" style="display: inline;"> - Page Likes</font></a>           
</ul>

Jquery Code is something like this:

var headTags = $("div#word_content").find("*").filter(function(){
                return /^h/i.test(this.nodeName);
              });

              var output = {};

              $(headTags).each(function(){
                var currentHead = $(this);

                var nextNextElem = currentHead.next().next();
                var innerText = [];
                if(nextNextElem.prop("tagName") == "UL")
                  {
                     nextNextElem.find("li").each(function(){
                       innerText.push($(this).text());
                     });  

                  }

                output[currentHead.text()] = innerText;
              });  

Currently, the Jquery is fetching the data, but it is capturing only the text and not the link. I need to parse the link as well, so that this link could be used in further pages. Can someone please help.

Answer 1

use this:

 nextNextElem.find("a").each(function(){
         innerText.push($(this).text()+" & href is:"+$(this).attr("href"));                   
                         }); 

var headTags = $("div#word_content").find("*").filter(function(){ 
 return /^h/i.test(this.nodeName); 
 }); 

 var output = {}; 

 $(headTags).each(function(){ 
 var currentHead = $(this); 

 var nextNextElem = currentHead.next().next(); 
 var innerText1 = []; 
 if(nextNextElem.prop("tagName") == "UL") 
 { 
 nextNextElem.find("li").each(function(index){ 
 innerText1.push(this.firstChild.data);
 $(this).children().each(function(index){ 
 innerText1.push("<a href='"+$(this).attr("href")+"'>"+$(this)[0].innerText+"</a>"); 
    if($(this).prop('nextSibling')){
    innerText1.push($(this).prop('nextSibling').nodeValue);
         }
 }); 
 }); 

 } 

 output[currentHead.text()] = innerText1; 
 });      console.log(output);
             $("#data").html(JSON.stringify(output));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
   <div id="word_content">

Answer 2

You can use something like this to parse links in the site:

$("a").each(function(i, o) {
    console.log("Link: " + (i + 1));
    console.log("  Text is: " + $(o).text());
    console.log("  Link is: " + $(o).attr('href'));
})

Result:

www.mytarget.com=
https://www.myPage.com/lolPagess/?id=06

See JsFiddle

Answer 3

Check every href inside an a

$("a").each(function () {
    isUrlValid($(this).attr("href"));
});

borrowed from Validating url with jQuery without the validate-plugin?:

  function isUrlValid(url) {
        return /^(https?|s?ftp):\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i.test(url);
    }

This regex will test for valid url's.
