Hi SnapDive,

Yes, you are correct! Forcing large sized XML document, we can combine
XmlReader and LINQ to XML to query the XML data, so as to decrease the
memory cost. For detail, please refer to the following code snippet:
================================================================
using (XmlReader reader = XmlReader.Create("MyXml.xml"))
{
  reader.MoveToContent();
  while (reader.Read())
  {
    if (reader.NodeType == XmlNodeType.Element)
    {
      if (reader.Name == "subpart")
      {
        XElement ele = XElement.ReadFrom(reader) as XElement;
        if (ele != null)
        {
          var query = from element in ele.DescendantNodesAndSelf()
                      where element.NodeType == System.Xml.XmlNodeType.CDATA
                      let CDataElement = element as XCData
                      where CDataElement.Value.Contains("&")
                      select CDataElement;

          foreach (var q in query)
          {
            MessageBox.Show(q.Value);
          }
        }
      }
    }
  }
}
================================================================
