Hi everybody,
I have to build an application that translates documents from an A-XML
format to a B-XML format. The problems need a lot of elementary methods
translating an a-node to a b-node, so I thought to encapsule these
functions in some classes, using a sort of Command pattern.
Do you have any other suggestion about?
Thanks in advance,
Kind regards,

Would xslt suffice? You can use this with streams for maximum efficiency,
plus it is designed to do this job...

I know...
But I have to implement in a .NET dll something that was before implemented
using XSLT... so I cannot give the customer back the same thing he gave me! :-)
Anyway: we need s .NET dll because this "translator " must be used in a
complex scenario by some different applications.
Thanks,
Giulio
A .net dll doesn't preclude using xslt to do the work; quite the opposite,
as below; you can always pass in additional options with your xml to control
the output if you need. By using xslt you get to capitalise on the transform
functions, including indexing, Munchean grouping, pattern-matching etc. But
its your call.
I can't advise on the command-pattern usage, as it just isn't the way I
would have thought of doing it... back to the floor - any takers?
Marc
// load the xslt template as a string from a resx
XmlDocument sourceDoc = new XmlDocument();
sourceDoc.LoadX ml(TestProject. Properties.Reso urces.Transform );
// prepare a transform object
XslCompiledTran sform xsl = new XslCompiledTran sform();
xsl.Load(source Doc);
xsl.Transform(s ource, target);
Hi Marc,

But how can I log the "activity" of my application using xslt?
Thanks,
Giulio
Depends on what you mean by "activity"; if you mean individual runs of
the tranform (i.e. not the detail), then just log it in C# one side of
..Transform(); if you mean a blow-by-blow account of the steps you go
through, then I think (never tried) that you can use xsl:message (in
the xslt) to fire events back into C#; you catch them like:
XsltArgumentLis t args = new XsltArgumentLis t()
args.XsltMessag eEncountered += args_XsltMessag eEncountered; //
some handler; look at .Message
And use the overload on Transform() that accepts an XsltArgumentLis t
Marc
Working example:
using System;
using System.Xml;
using System.Diagnost ics;
using System.Windows. Forms;
using System.Xml.Xsl;
using System.IO;
public class Program {
static void Main() {
XmlDocument templateDoc = new XmlDocument();
templateDoc.Loa dXml(@"<?xml version=""1.0"" encoding=""UTF-8""
?>
<xsl:styleshe et version=""1.0""
xmlns:xsl=""htt p://www.w3.org/1999/XSL/Transform"">
<xsl:template match=""*"">
<xsl:message>Fo und <xsl:value-of select=""name() ""/></xsl:message>
<xsl:element name=""Freaked{ name()}"">
<xsl:apply-templates select=""*""/>
</xsl:element>
</xsl:template>
</xsl:stylesheet> ");
XslCompiledTran sform transform = new XslCompiledTran sform();
transform.Load( templateDoc);
XsltArgumentLis t args = new XsltArgumentLis t();
args.XsltMessag eEncountered +=new
XsltMessageEnco unteredEventHan dler(args_XsltM essageEncounter ed);
XmlDocument input = new XmlDocument();
input.LoadXml(" <Xml><Some><Dat a/><Data/></Some></Xml>");
using(MemoryStr eam stream = new MemoryStream()) {
transform.Trans form(input, args, stream);
Debug.WriteLine (transform.Outp utSettings.Enco ding.GetString( stream.ToArray( )));
}
}
static void args_XsltMessag eEncountered(ob ject sender,
XsltMessageEnco unteredEventArg s e) {
Debug.WriteLine (e.Message);
}

I've often seen Tkinter referred to as the "standard" Python GUI. I assume

We are looking for both python beginners and experts.

I proposed python as the main language for our next CAD/CAM

something I'll need in this case is some experience-based set
of rules about how to use python in this context.
For example... is defining readonly attributes in classes
worth the hassle ? Does duck-typing scale well in complex

The term "mock filesystem" refers to code allowing unit

in other ways "virtual" files, without any actual disk
access. Everything is held in memory and therefore fast,
without risk of damaging real files, and with none of the
messiness of leftover files after testing.
Googling the archives and the web suggests that only I and
Remy Blank have done much along these lines. I...

So, just a little while ago I had this flash of insight. It occurred
to me that, while of course in general there are very good reasons for
the conventional two-file header/implementation separation for each C++

simply introduces extra boilerplate overhead.
The particular case I have in mind is CppUnit tests. Each test header

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
