Hyperlink asp control doesn't appear when set

[mbewers1]

Hi, I've got an XML file with one <title> and one <link> attribute.
What I want to do is implement a hyperlink with the name of the <title> element and whose NavigateUrl property is set to the <link> element.

For an unusual reason, the hyperlink never appears but, when debugged, both items from the XML file are appended to the hyperlink. What have I done wrong?

Cheers,
Matt

private void ReadXML()
    {
        using (StreamReader sr = File.OpenText(xmlFile))
        {
            while (!sr.EndOfStream && sr.Read() > 0)
            {
                string line = sr.ReadLine();
                if (line.Contains("<title>"))
                {
                    // read until we reach </title>
                    HyperLink4.Text = line.Replace("<title>", ""); // read until <title>
                    HyperLink4.Text = line.Replace("</title>", ""); // read until <title>
                }
                // link should follow straight after
                else if (line.Contains("<link>"))
                {
                    HyperLink4.NavigateUrl = line.Replace("<link>", "");
                    HyperLink4.NavigateUrl = line.Replace("</link>", ""); // read until <title>
                }
            }
        }
    }

Could you post your input and expected output?
It looks like you have something like
<title>Search </title><link>htt p://www.google.ca</link>
Which ends up being:
Searchhttp://www.google.ca

Did you want your output in html link form, eg
<a href="http://www.google.ca"> Search</a>
or some other different form?

Sure, my input is:

<rss version="2.0" xmlns:media="ht tp://search.yahoo.co m/mrss/"><channel>
<title>BBC News | UK | UK Edition</title>
<link>http://news.bbc.co.uk/go/rss/-/1/hi/uk/default.stm</link>

An I expect my output to be:

BBC News | UK | UK Edition

I guess HTML form would be more flexible than an asp:Hyperlink object but it doesn't really matter, I just want to turn the titles within the file into hyperlinks which the user can use to go directly to the report

Ah, I see, the problem is that you're overwriting it. eg, you'd get

Text = "BBC News | UK | UK Edition</title>" with <title> removed, then
Text = "<title>BBC News | UK | UK Edition" with </title> removed.

string line = sr.ReadLine(); 
int i = line.IndexOf("<title>");
int j = line.IndexOf("</title>");

// If you have a multi-line title, this won't deal with it.
if(i != -1 && j != -1)
{
  HyperLink4.Text = line.Substring(i, j-i);
}

and do the same thing with link.

You are assuming each element only comes on one line each, correct?

It's OK, I've solved this by using a better a approach - using Repeaters, Literals and Hyperlinks.

For the benefit of newbies to rss, just like me, this is the site I used:
