Is there an XPath querey that will select all the nodes from one arbitrary node to a second node?

for (int i = 1; i < lXPaths.Count; i++)
{
    string sXPathQuery = ????;  // perhaps some string using lXPath[i-1] & lXPath[i] 
    HtmlNodeCollection nTopic = htmDoc.DocumentNode.SelectNodes(sXPathQuery);
    .
    .
    .
}
