  • 0

I am working on project using asp.net mvc3 C# . I want to change some html element

attributes by c# like width , height etc. I have a simple (_Layout.cshtml) file

    <html> <head>
    <link href="@Url.Content("file.css")" rel="stylesheet" type="text/css" />
    <body>

     <a href="#" id="link1" title="@Function.ConfigElement("FacebookLink")" ></a>

     </body>
    </head> </html>

So i am using html agility pack to load and save this file

HtmlDocument doc= new HtmlDocument();

doc.load("_Layout.cshtml");

doc.GetElementbyId("link1").Attributes.Add("title", "@Function.ConfigElement("NewLink")");

doc.save("_Layout.cshtml");

After saving file output is like this

<html> <head>
        <link href="@Url.Content("file.css")"="" rel="stylesheet" type="text/css" />
        <body>

         <a href="#" id="link1" title="@Function.ConfigElement("NewLink")"="" ></a>

         </body>
        </head> </html>

in (link href) and (anchor title) saving some extra characters

How can i avoid this problem ..
Is there any other solution for parse html in c# for asp.net mvc.

Actually I want to add some server side function in these html element attributes

    As StackOverflow’s syntax highlight subtly hints, your HTML is extremely invalid.

    href="@Url.Content("file.css")"

    This is actually two attributes: href="@Url.Content(" and file.css")". (which has no value)

    You can’t use an HTML parser to parse Razor markup.
    Instead, you should use the actual Razor parser.
