替换为＆和＆W3C验证器仍然显示错误

Question

I'm trying to fix w3 validator based errors on my site but i'm shocked when i see this error

Error: & did not start a character reference. (& probably should have been escaped as &.)

I'm using & as a replaced tag with & in site HTML. So why w3c validator showing errors to replace & with & because i already done it.

Can anyone help this issue ?

Answer 1

It looks like you're probably using & unescaped in href attributes.

Error: & did not start a character reference. (& probably should have been escaped as &.)

At line 1647, column 65

bel/Simulation?&max-results=6'

It's often overlooked, but & should also become & in all similar locations:

bel/Simulation?&max-results=6
<!-- becomes -->
bel/Simulation?&amp;max-results=6

Answer 2

In all of those validation errors (from number 6 to 49), the ampersand is not necessary because you are passing a unique parameter.

<a href='//www.urgentfiles.com/search/label/Action?max-results=6'>
    Action
</a>

In cases with a URL containing two or more parameters, you need a double escape like & to correct the issue. For example.

<a href='//www.urgentfiles.com/search/label/Action?max-results=6&amp;amp;other-param=demo'>
    Action
</a>

Answer 3

You need to change the URLs and the parameters too. Consider two examples:

<link type='text/css' rel='stylesheet' href='https://www.blogger.com/dyn-css/authorization.css?targetBlogID=1668100655847438073&zx=0bb1bf52-b577-4cae-9e5b-60d9a3bd54cf' />

Should be replaced with:

<link type='text/css' rel='stylesheet' href='https://www.blogger.com/dyn-css/authorization.css?targetBlogID=1668100655847438073&amp;zx=0bb1bf52-b577-4cae-9e5b-60d9a3bd54cf' />

And the next series of ones:

<li><a href='http://www.urgentfiles.com/search/label/Action?&max-results=6' title='Action'>Action</a></li>
<li><a href='http://www.urgentfiles.com/search/label/Adventure?&max-results=6' title='Adventure'>Adventure</a></li>

Should be:

<li><a href='http://www.urgentfiles.com/search/label/Action?&amp;max-results=6' title='Action'>Action</a></li>
<li><a href='http://www.urgentfiles.com/search/label/Adventure?&amp;max-results=6' title='Adventure'>Adventure</a></li>
