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.Whitespa ceHandling=Whit espaceHandling. None;
//xmlDoc.Load(rea der);
while (reader.Read())
{
if (reader.NodeTyp e == XmlNodeType.Ele ment)
{
switch (reader.LocalNa me)
{
//case "ROW":
//string thisC=reader.Va lue;
//string thisC = reader.ReadElem entString();
// builder.Append( getData(reader) );
// break;
case "tx_name":
//string thisC=reader.Va lue;
//string thisC = reader.ReadElem entString();
//reader.MoveToCo ntent();
builder.Append( reader.Value.To String());
break;
}
}
}
//XmlNodeList requestNodeList = xmlDoc.SelectNo des("//request");
//lblXML.Text = requestNodeList .Count.ToString ();
//DisplayChildEle ments(xmlDoc.Do cumentElement, false);
if (builder.Length >0)
{
lblXML.Text=bui lder.ToString() ;
}
else
{
lblXML.Text="no xml data";
}
}
public string getData(XmlRead er reader1)
{
StringBuilder thisPN = new StringBuilder() ;
while(reader1.R ead() )
{
switch (reader1.Name)
{
case "img_name":
thisPN.Append(g etImageName(rea der1));
break;
}
if (reader1.NodeTy pe==XmlNodeType .Element ||
reader1.NodeTyp e==XmlNodeType. Whitespace)
{
switch (reader1.Name)
{
case "tx_name":
thisPN.Append(r eader1.ReadStri ng());
break;
}
}
}
return thisPN.ToString ();
}
public string getImageName(Xm lReader reader1)
{
StringBuilder thisPN = new StringBuilder() ;
while(reader1.R ead() )
{
if (reader1.NodeTy pe==XmlNodeType .Element ||
reader1.NodeTyp e==XmlNodeType. Whitespace)
{
switch (reader1.Name)
{
case "DATA":
thisPN.Append(r eader1.ReadStri ng());
break;
}
}
}
return thisPN.ToString ();
}
}
}
