Using the XML Destination Component

The XML Destination Component is an SSIS destination component used to merge input data based on the XML data structure defined in the component. You can then specify the component to write the merged XML document to a local file or you can send it to a HTTP URL to perform an XML or SOAP-based service call.

General Page

The General page determines what will happen with merged XML documents. The connection manager property can either be set to an HTTP Connection Manager which is used to send the document as part of an HTTP request, or a local file which is used to output the merged XML to a file.

Local File

SSIS XML Destination - Local File

  • Local File Path - The path on the file system where the XML document will be saved.

HTTP Connection Manager

SSIS XML Destination - HTTP

If an HTTP connection manager is selected the UI will display request settings that are used to determine the content of HTTP requests.

HTTP Method
The HTTP method that will be used to send requests.
Relative Path
The relative path is the second part of the URL that will be used to make the HTTP request. It is combined with the base path from the connection manager to form the full path. The relative path can contain query string parameters, but they can also be added individually in the grid below.
Query String Parameters
Query string parameters that will be appended to the full path when sending HTTP requests.
Request Headers
Request headers that will be combined with the headers in the connection manager and included with HTTP requests.
Request Body
The body of the HTTP request.
Batch Mode
Input rows can be batched and sent in a single request.  There are 3 batch modes:
  • Every Row - This mode is like a batch size of 1. A single web request will be sent or file created using the merged XML from each input row.
  • Entire Buffer - This mode is like an unlimited batch size. Only one web request or file will be created, and it will contain the merged XML from all the input rows.
  • Every Batch - This mode lets you specify the batch size. Some number of web requests will be sent or files created, each containing the merged XML from the number of rows specified in the batch size property.
Batch Size
If the batch mode is set to every batch the batch size can be specified.
Expression Editor Request Tokens

Many of the properties on this page can be set as either a text merged field or an expression.  Properties default to text merge mode, but can be changed to expression mode in the Expression Editor. The expression editor for a property can be launched by clicking the fx button.  The expression editor has some predefined tokens:

The number of the batch that is about to be sent. On the first request it will have a value of 1.
This is the merged document that was created for the current batch.
This token is only available in the item key field on the output columns page. It represents an item in the array of response items.
Expression Editor Text Merge Mode

SSIS XML Destination - Expression Editor Text Merge Mode

In text merge mode, property values will be whatever text was entered, but with any variables or special tokens replaced with their actual values before each HTTP request is sent.

Expression Editor Expression Mode

SSIS XML Destination - Expression Editor Expression Mode

In expression mode the property is set to an expression which is evaluated before each request to determine the value of the field.  Expressions can contain variables and special tokens, but also functions and conditional logic. The functions in the Value Lookup Functions category may be particularly useful for this component, as they can be used to look up values and XML documents and HTTP headers.

Merged XML

The Merged XML page determines how input columns will be used to create the merged XML document. It is divided into three parts: Design, Input Columns and Advanced.


Define the relationship of the Inputs in the Design Page.

SSIS XML Destination - Merged XML - Design

To define relationships simply click and drag from a child field to a parent field. In the above example, there is a relationship from the Item.PurchaseOrderId field to PurchaseOrder.Id field. What this means when merging is PurchaseOrder nodes will contain Item nodes whose PurchaseOrderId field match the PurchaseOrder's Id field. If you need to remove a relationship on the design page, simply select the connecting arrow and press the 'Delete' key.

You cannot continue to the Columns Page until the relationship structure is valid. The most common cause for an invalid relationship is invalid root count. The root input is defined be an input who does not have a parent Input. There must be one and only one root input. To fix this, delete any unused inputs and adjust the relationships so that there is only one root.

Input Columns

Configure column/node specific merge settings.

SSIS XML Destination - Merged XML - Input Columns

When navigating to the Columns Page for the first time a default XML structure will be generated. As specified in the note at the top of the Columns Page, you can add, remove, and move nodes. When adding nodes, a child node will be added to the currently selected node. If no node is selected then a root node is added. When you drag and drop one node onto another the moving node (and its children) will become a child of the target node. When you drag and drop one node onto no node (white space) then the moving node will become a root node. Note that some structural changes are not permitted as they would break the relationship defined on the Design Page. You can customize each node with the following properties:

XML NameThis property is a drop down list which contains all of the prefixes defined in the Namespaces data grid in the Advanced Page along with two special prefix properties:  

XML Name

This is the name of the element/attribute as it will appear in the XML document.

Input Column

The column to use as the value for the element/attribute.

Static Value

The value of the element/attribute. This can be plain text or an SSIS variable. Use this option instead of mapping a column if the value is the same for every occurrence of the node in the XML document.


This property is a drop down list which contains all of the prefixes defined in the Namespaces data grid in the Advanced Page along with two special prefix properties:  

  • <<Inherit>> - The current node will use the same prefix used by its parent. If the current node is the root node, then no prefix is used.
  • <<None>> - The current node will use no prefix, even if its parent does.
XML Type

This defines how the node(s) will be printed in the XML Document. There are 5 different XML Types:

  • Complex Element - an element that has child elements. You may not map a column or set a static value to complex element nodes.
  • Repeating Complex Elements - a complex element that occurs multiple times. This type can only be used on Inputs (green rows).
  • Element - an element with a value that comes from either an input column or a static value.
  • Repeating Elements - an element that occurs multiple times. When set to an input (green row) the number of rows determine how many times an element repeats. When set to a yellow row, the data will be parsed using the Repeating Elements (Column) Settings on the Advanced Page to print repeating elements.
  • Attribute - an attribute of the parent element containing a value that comes from either an input column or a static value.

Null Mode

This property specifies how to handle NULL values. There are three options: 

  • Don't Show - This option will hide nodes whose values are NULL.
  • Empty String - This will convert NULL values to empty string.
  • xsi:nil - This option will add xmlns:xsi="" to root of the XML and will add empty nodes with an attribute of xsi:nil set to "true" whose values are NULL. 
Print Pretty

When true, the merged XML will contain line breaks and indents. When false, the merged XML will be a single line of text.

Hide Declaration

Specifies whether or not the merged XML should contain the XML Declaration line.

Is Standalone

An attribute in the XML Declaration.

Merge Mode

Specify how to merge the inputs into XML. There are three different Merge Modes:

  • Every Row - This creates an XML document for each record in the root Input. Notice when this option is selected, the columns of the root input are directed to the Default Output. Another thing to notice is the plural node for the root Input is removed.
  • Every Batch - This creates an XML document for every batch. The size of the batch is determined by the Batch Size property, and a batch item is equivalent to one record in the root input. In other words, a batch size of 10 will create XML documents that each contain 10 root input records.
  • Entire Buffer - This creates a single XML document.
Batch Size

Specifies how many root input records should be in each XML document. This option is only available if the Merge Mode is Every Batch.

Text Qualifier

The qualifier used to split data into repeating elements.


The delimiter used to split data into repeating elements.


Add and remove namespaces (by clicking the '+' and '-' buttons) and assign them prefixes to be used in the merged XML

Output Columns

Output columns can be configured on this page.  The values of output columns will be extracted from the response of any HTTP requests that are sent. Output columns are typically used to get success or Id information about items you were created/updated or deleted on the server.

SSIS XML Destination - Output Columns

Response Is Array
Check this property if the HTTP response will contain an array with items corresponding to your input rows.  If the response does not contain information about each input item you wouldn't need to check this property.
Response Collection Base Path
If your response contains an array, the response collection base path property will be the XPath that will return the items in the array.
Response Item Lookup Strategy
If your response is an array a strategy must be selected to match input rows to response array items.
  • Sequential Strategy - If this strategy is selected it is assumed there are an equal number of input rows and output array items, and they are matched in the order they appear.
  • ItemLookup strategy - Use this strategy when the output array items are not in the same order as the input rows.  Selecting this strategy will allow you to define an item key below which will determine how input rows are matched to output array items.
Item Key
If the item lookup strategy is used an item key expression must be defined.  This expression will be evaluated for each input row in the batch and each array item in the response and should return true for a match and false when they are not a match.  The CurrentItem token is available in the expression editor and will allow a value from an array item to be easily compared to a column value to match rows and response array items.
Output Columns Grid
The output columns grid contains any output columns.  Output column values will always come from the HTTP response.  If the response is not an array the relative path should be the full Xpath to the output value in the HTTP response.  If the response is an array the relative path will be return the value at the specified XPath for the response array item that has been matched to the current output row.
HttpBody Checkbox
Checking this box will add an output column that contains the HTTP body of the response.
HttpResponseCode Checkbox
Checking this box will add an output column that contains the HTTP response code of the response.
HttpResponseCodeName Checkbox
Checking this box will add an output column that contains the HTTP response code name of the response.

Error Handling

This page allows you to specify how errors should be handled when they happen along with the name of the output column that will contain the merged XML.

SSIS XML Destination - Error Handling

Error Handling has three options available. 

  1. Fail on error
  2. Redirect rows to error output
  3. Ignore error

When the Redirect rows to error output option is selected, rows that failed to be sent will be redirected to the 'Error Output' output of the Transformation Component. As indicated in the screenshot below, the blue output connection represents rows that were successfully sent, and the red 'Error Output' connection represents rows that were erroneous. The 'ErrorMessage' output column found in the 'Error Output' may contain the error message that was reported by the component.
