Hi,

C#

XmlDocument xmlDom = new XmlDocument();
xmlDom.Load("D:\CPDCL_01HW342889_ALL_new.xml");

According to me Innerxml data member of XmlDocument can not able to hold this large string data, as its showing innerxml out of memmory exception, when we load the XML.

Since XML file is 135 MB, so we can not attach. So please let me know how to load the large (135 MB).
XML file.

Thanks
Abhi

==============================

The error message was showing as follows,

InnerXml = Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.

Try to convert it to stream and then load in XMLDocument.

FileStream filestream = File.OpenRead(pathtofile); 
XMLDocument objDOM = new XMLDocument();
objDOM.Load(filestream)

Have you tried loading it using linq to XML using xelement.load ? I believe it's a smaller foot print the xmldocument, although I could be wrong on that.

Try to use this one:

XmlTextReader myTextReader = new XmlTextReader(filename);
myTextReader.WhitespaceHandling = WhitespaceHandling.None;
while (myTextReader.Read())
{
if (myTextReader.NodeType == XmlNodeType.Element &&
myTextReader.LocalName == "Reward" &&
myTextReader.IsStartElement() == true)
{
ProcessRewardNode(myTextReader);
myTextReader.Skip();
}
}

private void ProcessRewardNode(XmlTextReader RewardReader)
{
XmlDocument RewardXmlDoc = new XmlDocument();
RewardXmlDoc.LoadXml(RewardReader.ReadOuterXml());
// we can use xpath as below
myID = RewardXmlDoc.SelectSingleNode("Reward/myID").InnerText;
}
