Linq solution:

var content = XDocument.Load("content.xml")
                       .Root.Elements("page")
                       .ToDictionary(p => (int)p.Attribute("no"));

var xdoc = XDocument.Load("template.xml");

foreach (var page in xdoc.Descendants("page"))
{
    XElement data;
    if (!content.TryGetValue((int)page.Attribute("no"), out data))
        continue;

    page.ReplaceNodes(data.Nodes());
}
