Multiline Textboxes make for happy XmlTextWriter results
This is not what I wanted to be spending the majority of my late-night coding session on tonight, but here we are:
Tonight's lesson: If you want to display the results of an XML file straight-up with indentations and format you are accustomed to simply and quickly, do NOT display it in a label control. Send it instead to a multi-line Textbox.
I got sidetracked into updating an XPath test page I use in the course of coding, based on one of many good code examples in Wrox's Professional ASP.NET XML with C#. I last wrote on this in a June post.
At bottom is the comparison between displaying the XML file in a textbox (at left in white) and a label (in pink). I anticipate someone telling me I missed some label attribute or perhaps should have used encoding of some kind, which I would of course welcome. Here's the code for a quick display of the XML file.
string _XmlDocPath =Server.MapPath(Request.ApplicationPath + "/xml/" + txtFilename.Text);
StringWriter sw = new StringWriter();
XmlTextWriter writer = new XmlTextWriter(sw);
writer.Formatting = Formatting.Indented;
writer.Indentation = 4;
XmlDocument doc = new XmlDocument();
txtResults.Text = sw.ToString();
SubSelectLabel.Text = sw.ToString();
