# New-XDocument no longer requires the “xe” command as long as the name of your XML Element doesn’t coincide with that of a PowerShell command (if it does, you need the “xe” on the front), and namespaces can be referred to by short name like dc:creator to keep things simple. Please review the examples on New-XDocument as this is a breaking change.
# h4. The other functions round out the set of XML functionality (especially if you don’t have PSCX).
# In particular, my Select-XML improves over the built-in Select-XML by leveraging Remove-XmlNamespace to provide a -RemoveNamespace parameter — if it’s supplied, all of the namespace declarations and prefixes are removed from all XML nodes (by an XSL transform) before searching (so you can actually find things, even with namespace-qualified xml). It is important to note that this means that the returned results will not have namespaces in them, even if the input XML did.
# Also, only raw XmlNodes are returned from Select-Xml, so the output isn’t quite compatible with the built in Select-Xml — instead, it’s equivalent to using it the way I usually do: Select-Xml ... | Select-Object -Expand Node
# New: Format-XML handles paths too :)
#
#requires -version 2.0
# Improves over the built-in Select-XML by leveraging Remove-XmlNamespace http`://poshcode.org/1492
# to provide a -RemoveNamespace parameter -- if it's supplied, all of the namespace declarations
# and prefixes are removed from all XML nodes (by an XSL transform) before searching.
# IMPORTANT: returned results *will not* have namespaces in them, even if the input XML did.
# Also, only raw XmlNodes are returned from this function, so the output isn't completely compatible
# with the built in Select-Xml. It's equivalent to using Select-Xml ... | Select-Object -Expand Node
# Version History:
# Select-Xml 2.0 This was the first script version I wrote.
# it didn't function identically to the built-in Select-Xml with regards to parameter parsing
# Select-Xml 2.1 Matched the built-in Select-Xml parameter sets, it's now a drop-in replacement
# BUT only if you were using the original with: Select-Xml ... | Select-Object -Expand Node
# Select-Xml 2.2 Fixes a bug in the -Content parameterset where -RemoveNamespace was *presumed*
# Version 3.0 Added New-XDocument and associated generation functions for my XML DSL
# Version 3.1 Fixed a really ugly bug in New-XDocument in 3.0 which I should not have released
# Version 4.0 Never content to leave well enough alone, I've completely reworked New-XDocument
# Version 4.1 Tweaked namespaces again so they don't cascade down when they shouldn't. Got rid of the unnecessary stack.
# Version 4.2 Tightened xml: only cmdlet, function, and external scripts, with "-" in their names are exempted from being converted into xml tags.
# Fixed some alias error messages caused when PSCX is already loaded (we overwrite their aliases for cvxml and fxml)
# Version 4.3 Added a Path parameter set to Format-XML so you can specify xml files for prety printing

#.Synopsis
# The Select-XML cmdlet lets you use XPath queries to search for text in XML strings and documents. Enter an XPath query, and use the Content, Path, or Xml parameter to specify the XML to be searched.
#.Description
# Improves over the built-in Select-XML by leveraging Remove-XmlNamespace to provide a -RemoveNamespace parameter -- if it's supplied, all of the namespace declarations and prefixes are removed from all XML nodes (by an XSL transform) before searching.
#
# However, only raw XmlNodes are returned from this function, so the output isn't currently compatible with the built in Select-Xml, but is equivalent to using Select-Xml ... | Select-Object -Expand Node
#
# Also note that if the -RemoveNamespace switch is supplied the returned results *will not* have namespaces in them, even if the input XML did, and entities get expanded automatically.
#.Parameter Content
# Specifies a string that contains the XML to search. You can also pipe strings to Select-XML.
#.Parameter Namespace
# Specifies a hash table of the namespaces used in the XML. Use the format @{<namespaceName> = <namespaceUri>}.
#.Parameter Path
# Specifies the path and file names of the XML files to search. Wildcards are permitted.
#.Parameter Xml
# Specifies one or more XML nodes to search.
#.Parameter XPath
# Specifies an XPath search query. The query language is case-sensitive. This parameter is required.
#.Parameter RemoveNamespace
# Allows the execution of XPath queries without namespace qualifiers.
#
# If you specify the -RemoveNamespace switch, all namespace declarations and prefixes are actually removed from the Xml before the XPath search query is evaluated, and your XPath query should therefore NOT contain any namespace prefixes.
#
# Note that this means that the returned results *will not* have namespaces in them, even if the input XML did, and entities get expanded automatically.
