Formatting XmlTextWriter Output

[clintonG]

// I want this format...
<rss version="2.0"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:media="ht tp://search.yahoo.co m/mrss/">

The WriteStartEleme nt is used for the rss element and extended using the
WriteAttributeS tring method which outputs the version and namespace
attributes. Can someone tell me how to format the output as shown above?

With .NET 2.0 you can use
XmlWriterSettin gs writerSettings = new XmlWriterSettin gs();
writerSettings. NewLineOnAttrib utes = true;
writerSettings. Indent = true;
then use those settings to create your writer e.g.
using (XmlWriter writer = XmlWriter.Creat e(@"file.xml", writerSettings) )
{
// write XML here
}
That will not give exactly what you have specified above I think but at
least each attribute should be written on a line of its own.

Re: Formatting XmlTextWriter Output

Amazing!
The inclusion of the XmlWriterSettin gs object will not allow any string
arguments that contain a colon.

// this will now barf...
writer.WriteAtt ributeString("x mlns:dc", "http://purl.org/dc/elements/1.1/");

You need to use
write.WriteAttr ibuteString(
"xmlns",
"df",
"http://www.w3.org/2000/xmlns/",
"http://purl.org/dc/elements/1.1/"
);
or
write.WriteAttr ibuteString(
"xmlns",
"df",
null,
"http://purl.org/dc/elements/1.1/"
);

Re: Formatting XmlTextWriter Output

I try to read documentation but I didn't observe how to use overloaded
methods in this context. The documentation certainly appears to be
consistent. Could you tell me what part of the documentation typifys methods
which can be overloaded? I mean what I need to learn to look for?

I'll try it out Martin and thanks fro bringing this to my attention...

Re: Formatting XmlTextWriter Output

No errors but...

// same single line persists
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">

And...I'm in some relevant documentation at the moment [1] but observe
undocumented parameters being used, i.e. null and your suggested alternative
use of "http://www.w3.org/2000/xmlns/" both of which I've tried but still
get a single line result.

// As documented [1] the method takes two and only two arguments

Re: Formatting XmlTextWriter Output

Got the documentation and parameter list issue resolved. Still left with
trying to resolve why the XmlWriterSettin gs object properties are not being
applied.

I am not sure why the xmlns declarations end up on the same line, that
seems a bug to me. Or the writers of the XmlWriter API treat xmlns
declaration attributes intentionally different although I can't see a
reason for that, if NewLineOnAttrib utes is true then that should apply
to xmlns attributes as well in my opinion.

I'm going to try to replicate with a new file sometime today. With all the
brooha about XML being a readable format one would think there would have
been more emphasis on formatting the raw XML.

It was also interesting to note Intellisense displays a Settings property
for an instance of an XmlWriter object but barfs when it is used to try to
set a property. I think (what I consider to be a redundant) instance of an
XmlWriterSettin gs object is going to be required and will force all
attributes in the entire file to be formatted whether wanted or not. If it
actually functions fot this purpose. Thanks for paying attention...

[Tom Jackson]

Formatting XmlTextWriter Output

So far as I can tell, that is how settings are built and applied - just like you said - they apply to the whole document and I don't believe can be set on an element/attribute basis:

XmlWriterSettin gs settings = new XmlWriterSettin gs();
settings.Indent = true;
XmlWriter xw = XmlWriter.Creat e(filename, settings);

What I'm running into is where I want to assign both an attribute and content to an element, i.e. to produce

<content encoding="base6 4binary">encode d content here</content>

it doesn't like it unless I do a "WriteRaw" for the content:

xw.WriteStartEl ement("content" , null);
xw.WriteAttribu teString("encod ing", "base64binary") ;
xw.WriteRaw(mes sageContent);
xw.WriteEndElem ent(); // end the content element

This comes out fine, but I was just curious if there was another, better, way?

[Tom Jackson]

Formatting XmlTextWriter Output

It didn't like my XML in that post above. Here, again, is what I'm trying to produce:

"bracket" content encoding="base6 4encoding" "bracket" encoded content here....
"bracket" /content "bracket"

[Tom Jackson]

Formatting XmlTextWriter Output

3rd time's a charm? Just change out the semi-colons below for brackets. I tried typing "bracket" before, above, and it didn't like it/wouldn't post it.

;content encoded="base64binary";my encoded content here;/content;

What does "it doesn't like it" mean exactly? Which code exactly have you
tried? Which error exactly did you get?
