Vista - How do I read a XML file into a hash table?

Examples needed.

Thanks!

Just a quick hack:

PS>
"<hash><entry><key>foo</key><value>1</value></entry><entry><key>bar</key><value>2</value></entry></hash>" | out-file hashXML.txt
PS> $hashXML = [xml] (get-content hashXML.txt)
PS> $hashXML.hash.entry | % { $hash = @{} } { $hash += @{$_.key = $_.value} }
PS> $hash

Name Value
---- -----
bar 2
foo 1

Unless every element name is unique i.e. maxOccurs is never more than 1, I
don't see how this would be helpful? Hashtables perform fast lookups based
off of a unique key, if the key isn't unique then a hashtable is a good fit.
Did you know that if you just convert a string to [xml] you get a full
System.Xml.XmlDocument object? For example:

PS> $xml =
[xml]"<doc><element1>Foo</element1><element1>Bar</element1></doc>"
PS> $xml.doc

element1
--------
{Foo, Bar}

PS> $xml.doc.element1[0]
Foo

PS>$xml.GetElementsByTagName("element1")

#text
-----
Foo
Bar

Or you could use XPath expressions:

PS>$xml.SelectNodes("//element1")

#text
-----
Foo
Bar

Doh! That should be "if the key isn't unique then a hashtable is *not* a
good fit".
