How to check whether xml element contain special word and than remove it (with c#)

I write in C# (asp.net) and make one xml file from many others, but in this files there are element (villageName) with text that I want to change. I want to check whether it contain "c." in the start and than I want to remove it. The tag is repeated many times. Sometimes the value doesn't begin with "c." This is a part of my code. Maybe here I must write the check.

 foreach (XmlElement singer in doc.DocumentElement.GetElementsByTagName("singers").Item(0).ChildNodes)
        {

            {

                XmlNodeList placeName = singer.GetElementsByTagName(element + "Place");

                XmlNodeList areaName = singer.GetElementsByTagName(element + "Area");
                if (villageName.Count != 0 && areaName.Count != 0)
                {
                villages.Add(new AddLocation(villageName.Item(0).InnerText, areaName.Item(0).InnerText));
                }
            }
        }

This code should do the trick. Where instead of using a node list you reference the root node of whatever you are trying to perform the replacement on. Your code and question are a little unclear so I had to generalize it with the an XmlNodeList.

XmlNodeList nodeList = _xmlDoc.GetElementsByTagName("villageName");

            foreach (XmlNode node in nodeList)
            {
                if (node.InnerXml.Substring(0,1).Contains('c'))
                {
                    node.InnerXml.Remove(0, 1);
                }
            }
