what I am having now is:
public class XmlPrettyPrintFilter : TransformFilter
{
private bool contentComplete;
private readonly StringBuilder content;
public XmlPrettyPrintFilter(Stream baseStream)
: base(baseStream)
{
contentComplete = false;
content = new StringBuilder();
}
public override void Write(byte[] buffer, int offset, int count)
{
content.Append(buffer.ConvertToString());
contentComplete = buffer.Length < 28672;
if (!contentComplete) return;
var b = prettyPrint(content.ToString()).ConvertToByteArray();
BaseStream.Write(b, 0, b.Length);
}
private static string prettyPrint(string s)
{
var document = new XmlDocument();
document.LoadXml(s);
string xml;
var xmlReader = new XmlNodeReader(document);
using (var stringWriter = new StringWriter())
{
var xmlWriter = new XmlTextWriter(stringWriter)
{
Formatting = Formatting.Indented,
Indentation = 1,
IndentChar = '\t'
};
xmlWriter.WriteNode(xmlReader, true);
xml = stringWriter.ToString();
}
return xml;
}
}
it seems to work well. probably throws when the view is not valid xml, which
is kind of a good thing.
still that is hackish and should only be used during development, I suppose.
Any ideas of how to make this better are very welcome.
