FTP Credentials for MSBuild.ExtensionPack.Communication.Ftp

In my AfterBuild script I use the following method to upload the files to the deployment server:

<MSBuild.ExtensionPack.Communication.Ftp
TaskAction="UploadFiles"
Host="localhost"
FileNames="$(SomeFolder)\$(FileToUpload)"
UserName="myUserName"
UserPassword="myPassword"
RemoteDirectoryName="/" />

How can I load these credentials from a text file or an external source? What are the alternatives? I don't want to hard-code ftp credentials into my cproj files.

I used GranadaCoders method to answer my own question:

<MSBuild.ExtensionPack.Xml.XmlFile TaskAction="ReadAttribute" File="$(FTP_Credentials_File)" XPath="/parameters/setParameter[@name='host']/@value">
  <Output PropertyName="FtpHost" TaskParameter="Value"/>
</MSBuild.ExtensionPack.Xml.XmlFile>

<MSBuild.ExtensionPack.Xml.XmlFile TaskAction="ReadAttribute" File="$(FTP_Credentials_File)" XPath="/parameters/setParameter[@name='username']/@value">
  <Output PropertyName="FtpUserName" TaskParameter="Value"/>
</MSBuild.ExtensionPack.Xml.XmlFile>

<MSBuild.ExtensionPack.Xml.XmlFile TaskAction="ReadAttribute" File="$(FTP_Credentials_File)" XPath="/parameters/setParameter[@name='password']/@value">
  <Output PropertyName="FtpPassword" TaskParameter="Value"/>
</MSBuild.ExtensionPack.Xml.XmlFile>

<Message Text="Attempting to uploade $(GeneratedZipFile) to $(FtpHost) as read from $(FTP_Credentials_File) ..." Importance="high" />
<MSBuild.ExtensionPack.Communication.Ftp TaskAction="UploadFiles" Condition="Exists('$(FTP_Credentials_File)')"  Host="$(FtpHost)" FileNames="$(PublicFolderToDropZip)\$(GeneratedZipFile)" UserName="$(FtpUserName)" UserPassword="$(FtpPassword)" RemoteDirectoryName="/" />

Put the values in an external xml file. Read the values from the xml file into a variable.

EDIT:

You can add some basic error checking for the values.

See URL here:

http://tutorials.csharp-online.net/MSBuild:_By_Example%E2%80%94Dealing_with_MSBuild_Errors

Short example.. note the condition..and how it checks for an empty string.

    <Error Text="Unable to connect to webserver" Code="Deploy" Condition=" '$(WebURL)' == '' "/>
