Re: [WiX-users] Help with adding new elements using XMLConfig

2014-04-15 Thread Michael Turner 
Uma,

Apologies for the delayed response.  If you haven't figured it out already,
you only need to remove the parent 'SnippetDir' node, and all of its
children will be removed with it.  However, you will need to be clever with
your XPath to make sure you select the correct 'SnippetDir' node for removal
-- e.g., reference something unique from the "More Stuff" part.

For example, something like this:

\snippetsindex.xml"
Node="element" ElementPath="//SnippetCollection//Language"
VerifyPath="SnippetDir[\[]MoreStuff/@Foo='bar'[\]]" />

You should replace the MoreStuff/@Foo='bar' qualifier with something that
uniquely describes the SnippetDir that you're adding on installation. 
Remember that you need to use the "[\[]" and "[\]]" to escape the square
brackets that would otherwise be interpreted as MSI's "[PropertyName]"
syntax.

The XmlConfig Element documentation is not very clear on this point, but in
my experience, for a "delete element" action, ElementPath points to the
parent of the element you want to delete (so the same ElementPath you used
when creating it as Node="document"), VerifyPath is interpreted relative to
the ElementPath, and VerifyPath specifies what you want to delete.

(I didn't repeat the xmlns:util namespace declaration on the above example;
you should put this on a higher-level element in your file so that you don't
have to keep repeating it.)

Regards,
Mike

Re: [WiX-users] Help with adding new elements using XMLConfig

2014-03-28 Thread Uma Harano 
Hi Mike,
I got the installation to work using the Node="document" method. The xml 
content is now correctly written during install mode.
To remove the xml content during uninstall, I need to specify each node in a 
sequence (working from the child elements to outer elements), correct? I cannot 
use the Node="document" and pass the entire xml snippet?

Thanks!

Uma,

First of all, I don't think you can insert XML before a given node using
XmlConfig; you can only append a new child to a given parent node.
(http://stackoverflow.com/q/8224918)

Also, there are two nodes that match your XPath expression, and XmlConfig
only uses the first match.  Since you know that the node you have just added
will always be the last one (due to the append behavior), you should try
this XPath for your 1002 expression instead:

ElementPath="//SnippetCollection//Language/SnippetDir[\[]last()[\]]"

Notice that you must escape the square brackets per
http://msdn.microsoft.com/library/aa368609.aspx

I am not certain whether the last() function actually works on XmlConfig,
but this should get you closer.  If that does not work, then you can try
this instead:

  <util:XmlConfig On="install" Action="create"
Id="CreateSnippetDir" Node="document"
File="<Path to Xml>\snippetsindex.xml"
ElementPath="//SnippetCollection//Language"
  xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">;
 
<![CDATA[<SnippetDir><OnOff>Off</OnOff><!-- More
Stuff --></SnippetDir>]]>
  </util:XmlConfig>

If you use this, it can replace both of your XmlConfig elements, since it
combines them into a single operation.  Note the Node="document", which lets
you specify the XML content to insert, as inner-text of the XmlConfig node. 
I am not sure whether the Node="document" construct treats the inner-text as
a "Formatted String" (http://msdn.microsoft.com/library/aa368609.aspx) or
not, so if your "More Stuff" contains any square brackets or [PropertyName]
expressions, you may need to experiment to see how it behaves.

Regards,
Mike

Re: [WiX-users] Help with adding new elements using XMLConfig

2014-03-26 Thread Uma Harano 
Hi Mike,
Option 1 did not work - I got a message saying: 
"Failed to find snippet node //SnippetCollection//Language/SnippetDir[last()]"

With option 2 (which was very promising and such a simple solution for me) I 
get this error in the MSI log. The setup just rolls back immediately:
"ExecXmlConfig:  Error 0x8007006e: Failed to load value as document."

Note: for option 2, I do not have any square brackets or properties that need 
to be escaped. I even tried it with a very simple one line XML.

Thanks!
Uma-
