select-xml with namespace

Hello,

I am having difficulty selecting xmldata when it contains a namespace and can't seem to get the syntax correctly.

The xml data is

<?xml version="1.0" encoding="ISO-8859-1"?><nc:rpc-reply message-id="1" xmlns="http://www.cisco.com/nxos:1.0:nfcli" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0"><nc:data><show><version><__XML__OPT_Cmd_sysmgr_show_version___readonly__><__readonly__><header_str>Cisco Nexus Operating System (NX-OS) Software TAC support: http://www.cisco.com/tac Documents: http://www.cisco.com/en/US/products/ps9372/tsd_products_support_series_home.html Copyright (c) 2002-2013, Cisco Systems, Inc.

The output will vary slightly on the __XML line and the part near the top. This example I'm running the command show version. If I were to run the show inventory command it would pretty much look the same. The namespace is the same every time as well.

Either my xpath is incorrect or name space.

What I am trying to do is get the data between </__readonly__>

Any help would be appreciated.

For namespace I put

$namespace=@{xmlns="http://www.cisco.com/nxos:1.0:nfcli";"xmlns:nc"="urn:ietf:params:xml:ns:netconf:base:1.0"}
