Task: To Read an XML document and handle data contents in .NET for new
processing
Request: Any details on how to read an XML document processing all
nodes and content in .NET
Problems: Duplicate DATA tags, end nodes (ley01) and then data lower
down, system loses its positions
My Experience: Handling XML/HTML via Transforms, writing XML using
..NET, but not reading
SAmple Code:
XmlTextReader reader = new XmlTextReader(("0102020200_rei_uk.xml"));
XmlDocument xmlDoc = new XmlDocument();
//reader.WhitespaceHandling=WhitespaceHandling.None;
//xmlDoc.Load(reader);
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{
switch (reader.LocalName)
{
//case "ROW":
//string thisC=reader.Value;
//string thisC = reader.ReadElementString();
// builder.Append( getData(reader));
// break;
case "tx_name":
//string thisC=reader.Value;
//string thisC = reader.ReadElementString();
//reader.MoveToContent();
builder.Append(reader.Value.ToString());
break;
}
}
}
//XmlNodeList requestNodeList = xmlDoc.SelectNodes("//request");
//lblXML.Text = requestNodeList.Count.ToString();
//DisplayChildElements(xmlDoc.DocumentElement, false);
if (builder.Length>0)
{
lblXML.Text=builder.ToString();
}
else
{
lblXML.Text="no xml data";
}
}
public string getData(XmlReader reader1)
{
StringBuilder thisPN = new StringBuilder();
while(reader1.Read() )
{
switch (reader1.Name)
{
case "img_name":
thisPN.Append(getImageName(reader1));
break;
}
if (reader1.NodeType==XmlNodeType.Element ||
reader1.NodeType==XmlNodeType.Whitespace)
{
switch (reader1.Name)
{
case "tx_name":
thisPN.Append(reader1.ReadString());
break;
}
}
}
return thisPN.ToString();
}
public string getImageName(XmlReader reader1)
{
StringBuilder thisPN = new StringBuilder();
while(reader1.Read() )
{
if (reader1.NodeType==XmlNodeType.Element ||
reader1.NodeType==XmlNodeType.Whitespace)
{
switch (reader1.Name)
{
case "DATA":
thisPN.Append(reader1.ReadString());
break;
}
}
}
return thisPN.ToString();
}
}
}
