Commented Issue: xinclude / encoding problem

psohm — Thu, 04 Sep 2008 15:31:16 GMT

hello
i've a problem with encoding and i can't resolve it.
I have a project which use the .net 2 xml api and everything work fine.
but if i have a file which contains strange characters (i don't put an example, otherwise codeplex refuse my post), xinclude don't word (but .net work)

the error message is :
..., valeur hexadécimale 0x0B, est un caractère non valide. Ligne 3, position 31."

i have made an example project which reproduce the bug
do you know how to solve that problem ?
although i admit i'm a bit lost, i think it's a encoding problem

thanks

the xml example file is :

<?xml version="1.0" encoding="utf-8"?>

New Post: Where's the msi installer and where are the installation instructions?

After some research, I found the installer here:

abdu — Tue, 26 Aug 2008 08:11:43 GMT

The bin zip doesn't contain the msi installer plus there are no installation instructions.

A message mentions a video from dnrtv about the tool. The developer spends like 8 minutes talking about the tool and then jumps straight to the 'Other Windows' menu option where he shows the tool. Where's the part that shows how to install it so that it shows up in that menu option!!? Did I miss it?

New Post: Need help debugging MvpXslTransform

PeteM — Wed, 30 Jul 2008 11:53:16 GMT

Hi,
I'm having problems getting MvpXslTransform to work properly - can someone help?
Here's my code:
        public XmlReader GetXmlAsReader()
        {
            XElement qualification = GetQualification();
            XmlReader reader = null;
            XmlInput input = new XmlInput(qualification.CreateNavigator());
            MvpXslTransform transform = new MvpXslTransform(true);
            try { transform.Load(GetStylesheet()); }
            catch (Exception ex) { ... }
            try { reader = transform.Transform(input, null); }
            catch (Exception ex) { ... }
            return reader;
        }

The output of the reader (if, say, I output to a file) is an empty file. I don't understand why.
I basically need some ideas on how to debug this to find out why it's not working. I'm not very familiar with XmlReaders, and inspecting the properties & methods doesn't really highlight anything to me.

GetStylesheet() returns an XmlReader (but I've also tried with just a URI).
The XmlInput seems to be OK, although when I check it in the debugger my xml file is enclosed by "{" and "{" - is that to be expected?
I've used the stylesheet with a XslCompiledTransform, and it works as expected.

Any ideas, suggestions or pointers will be warmly welcomed!
Thanks in advance,
Peter.

If you check in the comments of Don's blog (http://donxml.com/allthingstechie/archive/2006/07/07/Intro-to-XPathmania-_2D00_-Extending-Visual-Studio-2005-to-Support-XPath-Development.aspx)
you'll see that someone's created an installer for VS2008.

Commented Issue: Cannot get XpathCache to replace variables.

dcazzulino — Tue, 08 Jul 2008 05:18:35 GMT

I cannot get XpathCache to replace dynamic xpath variables in my xpath expression. I know the expression evaluates if I hardcode some test values.

This works:
string MenuDepthXpathStr = "/descendant-or-self::ul[count(ancestor-or-self::ul) >= $depth]";
string Depth = "1";

XPathNodeIterator TempList = XPathCache.Select(MenuDepthXpathStr, MenuDocXml, new XmlNamespaceManager(MenuDocXml.NameTable), new XPathVariable("depth", Depth));

However this doesnt:
string MenuDepthXpathStr = "/descendant-or-self::ul[count(ancestor-or-self::ul) >= $depth $highlighted]";
string Depth = "1";
string Highlighted = (SomeBoolVal? "and contains(@class, 'expanded')" : "");

XPathNodeIterator TempList = XPathCache.Select(MenuDepthXpathStr, MenuDocXml, new XmlNamespaceManager(MenuDocXml.NameTable), new XPathVariable("depth", Depth), new XPathVariable("highlighted", Highlighted));

It seems as though my variable cannot contain xpath it can only be values. Why is this? Is there any way to dynamically generate the xpath itself and not just insert values?
Comments: ** Comment from web user: dcazzulino **

That's just now how xslt variables work. We're just making it easier to use a feature that's provided by the System.Xml.Xsl namespace. We can't make changes, and I don't anticipate MS doing them either.

Again, if you're invoking Sprocs, you cannot do that. I'm afraid this is internally (.NET) the same.

Closed Issue: XPathDocumentWriter::WriteRaw escapes XML when it shouldn't

dcazzulino — Sun, 06 Jul 2008 16:00:39 GMT

The WriteRaw method of the XPathDocumentWriter escapes the XML brackets < and > to < and > It seems that it behaves exactly as WriteString does.

Steps to reproduce:

XPathDocumentWriter xw = new XPathDocumentWriter();
xw.WriteStartElement("root");
xw.WriteRaw("<item>test</item>");
xw.WriteEndElement();
xw.Flush();
XPathNavigator xn = xw.Close();
Trace.WriteLine(xn.OuterXml);

The output is:

<root><item>test<item></root>

Whereas it should be:

<root><item>test</item></root>
Comments: Look in Reflector at the MS.Internal.Xml.Cache.XPathDocumentBuilder.WriteRaw implementation:

public override void WriteRaw(string data)
{
this.WriteString(data, TextBlockType.Text);
}

That's the wrapped class we're calling, it's provided by .NET and we can't change its behavior. So I guess you cannot use WriteRaw.

An alternative would be to parse the string with an XmlReader and use WriteNode instead.

Yup, I love this addin, but hate having to swap to 2005 to work with XML files - please, please, please can you update?

Me too. I tried updating the Add-In locations to search explicitly for the installation directory as well, but no dice.

I ran the XPathmania setup and it integrated fine in my VS2005, but not in my VS2008...

How can I make it integrate into my VS2008?

NEW POST: XpathMania, default namespace

jwessling — Mon, 25 Feb 2008 20:07:10 GMT

Hello,

I'm getting an error that the document I'm querying has a default namespace that needs to be included in the Namespace Table. I've added the namespace, but now I get an error that all namespaces need to have a prefix associated with them. How do I specify a prefix for the default namespace?

Thanks,
Jeff

CREATED ISSUE: XpathCache Select that returns XpathNavigator

aromero78 — Thu, 21 Feb 2008 14:46:49 GMT

Would it be possible to get a XPathCache.SelectSingleNode function that returns a XPathNavigator?

COMMENTED ISSUE: Cannot get XpathCache to replace variables.

aromero78 — Thu, 21 Feb 2008 14:43:43 GMT

If at all possible I'd rather not be protected from myself. Would it be possible to break out this functionality into two separate functions? An XPathCache.Select method that allows for any string to be added and a new function that would check a give string for xpath injection? That way in situations where I control all of the variables and know that xpath injection is not possible I could use the XPathCache class to build any Xpath statement I wanted and could still check for injection if need be.

We have no specific release plans at this point, i'm afraid

think of the xpathcache and pre-compiled xpath expressions as stored procedures.
The values you're replacing are not "string.format" kind of replacement. They are rather like sproc's parameters.

What you're trying to do is the equivalent of SQL injection but with xpath. it's called xpath injection and is something that doesn't work by design.
