Hi,

I need to be able to retrieve values from a string made up of HTML.  A
colleague has mentioned using regular expressions to retrieve the
value but this is proving quite difficult.  If someome could point me
in the right direction in regard to the values below, it would be
greatly appreciated.

<td class="brandorange">Quote reference: 123456789</td> - I need to
retrieve the 123456789 value.

<input type="radio" name="selections.excessBuildings" value="1">
£100<input type="radio" name="selections.excessBuildings" value="2">
£150<input type="radio" name="selections.excessBuildings" value="3"
checked="checked">£300<input type="radio"
name="selections.excessBuildings" value="4"> - I need to be able to
retrieve the checked value i.e. value '3' is checked so I need to
retrieve 300.

I wrote this method for you.
It works.

you have to pass the html string as parameter to this method

        string GetCheckedValue(string inputStringHtml)
        {
            string pattern = ".*checked=\"checked\"[^\\>]*\\>";
            string poundValue = "£0";
            Regex expression = new Regex(pattern);
            if(expression.IsMatch(inputStringHtml))
            {
                string[] split = expression.Split(inputStringHtml,2);
                expression = new Regex("\\<");
                if (expression.IsMatch(split[1]))
                {
                    string[] values = expression.Split(split[1]);
                    poundValue = values[0];
                }
            }
            return poundValue;
        }

In general regular expressions are a terrible way to parse HTML, because
most HTML is not very regular.  A simple regex that matches your current
example would fail if the site decides changes the HTML just a bit.

I suggest you investigate one of the available HTML parsers that can deal
with this variability:
