Reading XML in powershell : (407) Proxy Authentication Required error? - powershell

Question

I'm trying to read an XML file from my local machine. However, the following code:
$datasourceXmlFilePath=$configuration.config.mondrian.DataSources.filePath
$webXmlFilePath=$configuration.config.mondrian.web.'web-app'.filePath
if(!(Test-Path($datasourceXmlFilePath)))
{
Write-Host "Datasource.xml not found. Exiting the script" -ForegroundColor red
exit
}
if(!(Test-Path($webXmlFilePath)))
{
Write-Host "Web.xml not found. Exiting the script" -ForegroundColor red
exit
}
[xml]$datasourceXml=Get-Content $datasourceXmlFilePath
Write-Host "XML created"
[xml]$webl= Get-content $webXmlFilePath
Write-Host "XML Created"
Keeps giving me the following error:
XML created
Cannot convert value "System.Object[]" to type "System.Xml.XmlDocument". Error: "The remote server returned an error: (407) Pr
oxy Authentication Required."
At line:20 char:11
+ [xml]$webl <<<< = Get-content $webXmlFilePath
+ CategoryInfo : MetadataError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : RuntimeException
Both the XML's are well formed, and I'm stumped as to why one file is successfully read and why the other is not. I tried changing the location of the second xml file, but still got the same result.
I'm using WindowsPowershell_ise v1.0,running on a windows 7 machine.
The xml file for which the problem is occuring is:
<?xml version="1.0" encoding="UTF-8"?>

Any help would be appreciated.

Answer 1

I had a similar problem loading an XML. I didn't require proxy access but had trouble with circumventing it, initially I tried this:
set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' -name ProxyEnable -value 0
It worked as a user but not as administrator.
So I tried this:
[System.Net.WebRequest]::DefaultWebProxy = $null
