.aspx.cs code for adding a textbox entry to "[contains(title, 'TextboxEntry']"

I have a project which has a Search textbox for the user to enter keyword(s) to retrieve from an
.xml page called rss.xml.  In the .aspx.cs page I was instructed to do this by declaring a
string (sTemp) and sTemp = "[contains(title, 'asp')]" for example.  However, I now need to replace the
'asp' with whatever the user inputs into the textbox.  I've attached the back code that I'm using.
Any help would be GREATLY appreciated.
Thank you

protected void btnSearch_Click(object sender, EventArgs e)

        {

            string In = string.Empty;

            string SearchText =  txtSearch.Text;

            if (ddlSearchWhere.SelectedIndex == 0) -----this is from a dropdown list for the user to choose where they want their text searched----

                In  = "[contains(title,"+'txtSearch.Text')]";

            if (SearchText != null)

                SearchText = In;

                //In = "[contains(title, '" + SearchText;

            xmlDataSource1.DataFile = @"rss.xml";

            xmlDataSource1.XPath = @"rss/channel/item" + SearchText;// + sTemp;

            xmlDataSource1.DataBind();



            dtlDisplay.DataSource = xmlDataSource1;

            dtlDisplay.DataBind();

Do you code compile?

If not one error can be found in the statement assigning to you "In" variable.
To be valid this should be: "[contains(title, '" + SearchText + "')]";

...but an even better alternative would be: "[contains(translate(title, 'ABCDEF...VWXYZ', 'abcdef...vwxyz') , '" + SearchText.ToLower() + "')]";
since this will make your search case insensitive.

I guess I'm not real sure what you mean by "code compile", but I did try your solution and it makes PERFECT SENSE to me and I would have thought it would run great (I tried both solutions)....however,
with the second solution, I got no response when I ran it.......the first solution gave me an "XPath Exception was unhandled by user code" error & underneath it says ..."'rss/channel/item[contains(title, 'now')]' "...... has an invalid token.
This is MUCH better than what I was getting because it's at least recognizing the word 'now' which I typed in for the search text.
Any other suggestions?

I think there was an extra ( prior to "title" and that's why I was receiving the error, but all is FANTABULOUS ----- thank you sooooo much ----- I'm sold!!!!!!  SinaBug
