GetElementsBy ... (javascript)

Question

I want to get the href value of the link that has rel='edit', i am wondering how i can do it.

<link rel='self' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/****'/>
<link rel='edit' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/****'/>

I am trying

this.url = entry.getElementsByTagName('link')[1].getAttribute('href');

but i get href of the first link.

thanks.

EDIT :

now what i don't understand is thateven when i am sure i get the right link, the href value is not what i expect

<link rel='self' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/list/**********/full/ba0fz'/>
<link rel='edit' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/list/**********/full/ba0fz/27mpei328jki4e'/>

what i want is to do a regex on the href i want to get the "27mpei328jki4e" but instead of getting the full url, i get the short one, do you have any idea of why i get this result? no matter what method i use, neither the queryselector nor getElementsByTagName.

my document is an xml

<?xml version='1.0' encoding='UTF-8'?>

When you call getElementsByTagName, take a look at all of the elements in it - compare that to what's in your HTML - there's a difference somewhere, so it will help once you know what that difference is. — Joe Enos

That code above works you need to verify that those are the only 2 link's on the page before assuming that index 1 is the one you want. You might give them another arbitrary attribute then loop through the node list that getElementsByTagName returns until you find the one that has the href you want. — scrappedcola

Try using query selectors:

document.querySelector('link[rel="edit"]');
