XObject.IXmlLineInfo.LinePosition Property

Gets the line position that the underlying XmlReader reported for this XObject.

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

int IXmlLineInfo.LinePosition { get; }

Property Value

Type: System.Int32
An Int32 that contains the line position reported by the XmlReader for this XObject.

Implements

IXmlLineInfo.LinePosition

This method is an explicit interface member implementation of a method in the IXmlLineInfo interface, so in order to call this method, it is necessary to cast to IXmlLineInfo.

This example loads a small XML tree from a file, setting the options to set base URI and retain line information. It then adds another element that does not have line information. It then prints the line information for each element in the tree.

string markup = @"<Root>
    <Child1 />
    <Child2 />
    <Child4 />
</Root>";

File.WriteAllText("Test.xml", markup);

XElement po = XElement.Load("Test.xml",
    LoadOptions.SetBaseUri | LoadOptions.SetLineInfo);

// add a node to the tree.
// the newly added node will not have line information.
po.Element("Child2").AddAfterSelf(new XElement("Child3"));

string[] splitUri = po.BaseUri.Split('/');
Console.WriteLine("BaseUri: {0}", splitUri[splitUri.Length - 1]);
Console.WriteLine();
Console.WriteLine("{0}{1}{2}",
    "Element Name".PadRight(20),
    "Line".PadRight(5),
    "Position");
Console.WriteLine("{0}{1}{2}",
    "------------".PadRight(20),
    "----".PadRight(5),
    "--------");
foreach (XElement e in po.DescendantsAndSelf())
    Console.WriteLine("{0}{1}{2}",
        ("".PadRight(e.Ancestors().Count() * 2) + e.Name).PadRight(20),
        ((IXmlLineInfo)e).HasLineInfo() ?
            ((IXmlLineInfo)e).LineNumber.ToString().PadRight(5) :
            "",
        ((IXmlLineInfo)e).HasLineInfo() ?
            ((IXmlLineInfo)e).LinePosition.ToString() :
            "No Line Information");

This example produces the following output:

BaseUri: Test.xml

Element Name        Line Position
------------        ---- --------
Root                1    2
  Child1            2    6
  Child2            3    6
  Child3            No Line Information
  Child4            4    6
