Automate XML Integration Tasks from PowerShell

The CData ADO.NET Provider for XML is a standard ADO.NET Provider that make it easy to accomplish data cleansing, normalization, backup, and other integration tasks by enabling real-time and bidirectional access to XML.

ADO.NET Provider

The ADO.NET Provider provides a SQL interface for XML; this tutorial shows how to use the Provider to create, retrieve, update, and delete XML data.

Once you have acquired the necessary connection properties, accessing XML data in PowerShell can be enabled in three steps.

Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) XML Files

CData Drivers let you work with XML files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

Setting connection properties for local files

Set the URI property to local folder path.

Setting connection properties for files stored in Amazon S3

To connect to XML file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended XML files exist. In addition, at least set these properties:

• AWSAccessKey: AWS Access Key (username)
• AWSSecretKey: AWS Secret Key

Setting connection properties for files stored in Box

To connect to XML file(s) within Box, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Box.

Dropbox

To connect to XML file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

SharePoint Online (SOAP)

To connect to XML file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. Set User, Password, and StorageBaseURL.

SharePoint Online REST

To connect to XML file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended XML file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

Google Drive

To connect to XML file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended XML file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

• Document (default): Model a top-level, document view of your XML data. The data provider returns nested elements as aggregates of data.
• FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
• Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

See the Modeling XML Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

1. Load the provider's assembly:

   
   [Reflection.Assembly]::LoadFile("C:\Program Files\CData\CData ADO.NET Provider for XML\lib\System.Data.CData.XML.dll")
       

2. Connect to XML:

    
   $conn= New-Object System.Data.CData.XML.XMLConnection("URI=C:/people.xml;DataModel=Relational;")
   $conn.Open()
   

3. Instantiate the XMLDataAdapter, execute an SQL query, and output the results:

   
   $sql="SELECT [ personal.name.first ], [ personal.name.last ] from people"
   
   $da= New-Object System.Data.CData.XML.XMLDataAdapter($sql, $conn)
   $dt= New-Object System.Data.DataTable
   $da.Fill($dt)
   
   $dt.Rows | foreach {
   	Write-Host $_.[ personal.name.first ] $_.[ personal.name.last ]
   }
     

Update XML Data

$cmd =  New-Object System.Data.CData.XML.XMLCommand("UPDATE people SET [ personal.name.last ]='Roberts' WHERE Id = @myId", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.XML.XMLParameter("@myId","10456255-0015501366")))
$cmd.ExecuteNonQuery()

Insert XML Data

$cmd =  New-Object System.Data.CData.XML.XMLCommand("INSERT INTO people ([ personal.name.last ]) VALUES (@my[ personal.name.last ])", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.XML.XMLParameter("@my[ personal.name.last ]","Roberts")))
$cmd.ExecuteNonQuery()

Delete XML Data

$cmd =  New-Object System.Data.CData.XML.XMLCommand("DELETE FROM people WHERE Id=@myId", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.XML.XMLParameter("@myId","001d000000YBRseAAH")))
$cmd.ExecuteNonQuery()
