Howto: format attribtes per line rather then on one line

[Fred Heida]

Hi All,

Using the XmlDocument and XMLElement::SetAttribute
is there away to indent the attribute per line, rather hen them having them
on the one line
e.g
<MyRoot Att1="Value1" Att2="Value2"></MyRoot>
but
<MyRoot
Att1="Value1"
Att2="Value2"

</MyRoot>
Cheers,
Fred

I do not see anything in .NET 1.1 that would allow that, the
documentation for XmlTextWriter explicitly says that indentation applies to

DocumentType
Element
Kommentar
ProcessingInstruction
CDATASection

only.

You can create custom XmlWriter to workaround it:

public class AttributeIndentingXmlTextWriter : XmlTextWriter
{
private TextWriter w;
private int depth;

//Add constructors as needed
public AttributeIndentingXmlTextWriter(TextWriter w)
: base(w)
{
this.w = w;
}

public override void WriteStartElement(string prefix, string
localName, string ns)
{
depth ++;
base.WriteStartElement(prefix, localName, ns);
}

public override void WriteFullEndElement()
{
depth--;
base.WriteFullEndElement();
}

public override void WriteEndElement()
{
depth--;
base.WriteEndElement();
}

public override void WriteStartAttribute(string prefix, string
localName, string ns)
{
if (base.Formatting == Formatting.Indented)
{
w.WriteLine();
for (int i=1; i<Indentation*depth; i++)
w.Write(IndentChar);
}
base.WriteStartAttribute(prefix, localName, ns);
}
}

Then save XmlDocument via instance of an AttributeIndentingXmlTextWriter.
