Hi All,
I have a xml file that holds metadata properties info of an listitem in a library. The metadata properties holds some invalid hexadecimal characters. I use the below code to read the xml file, it throws invalid hexadecimal characters xml exception.
CharacterSettings - checkcharacter doesnt seem to work. can anyone help me on how to handle this exception to remove those invalid xml values:
SpFile ItemAuditFile = ListItem.File ;\\xml file with info on properties
Stream AuditFile = ItemAuditFile.OpenBinaryStream();
var charSettings = new XmlReaderSettings()
{
CheckCharacters = false
};
XmlReader xmlReader = XmlReader.Create(AuditFile , charSettings);
xmlReader.MoveToContent();
try
{
AuditXmlOriginal = xmlReader.ReadInnerXml();
}
catch
{
}
xmlReader.Close()Thanks,

The above references explains as how to validate a string. But the code throws the invalid value exception While trying to read the xml file to convert as a string on line - xmlReader.ReadInnerXml();
Sorry am not aware of it. Can you let me know as how to implement it in the above code.
Thanks,
