Question

I am trying to select an element by its type

//input[(@type = 'checkbox' or @type = 'radio') and @name = 'BigBobMcNob']

but its not matching, because my type is capitalised

<input type='Checkbox' name='BigBobMcNob' />

How do I fix that? and if I do will it break when selecting on class, which should be case sensitive?

You could just iterate through the node collection and check each node against your conditions like this:

var allowedName = "Checkbox";
var allowedTypes = new[] { "checkbox", "radio" };
var nodes = doc.DocumentNode.DescendantNodes()
    .Where(n =>
        n.Name == "input" &&
        allowedTypes.Contains(n.GetAttributeValue("type", null), StringComparer.OrdinalIgnoreCase) &&
        n.GetAttributeValue("type", null) == allowedName
    ).ToList();

For type attribute comparison, StringComparer.OrdinalIgnoreCase comparer is used; name attribute doesn’t require a special comparer.
