Load XML by SSIS - DTD is prohibited in this XML document error

问题


Hope you all are doing well.

Previously I asked a question how to import a XML file to SQL Server thanks to all you responses.

As my source file come with heavy amount of data, I am trying to load by SSIS. Below are the steps I followed:

  1. Imported XML by BulkLoad to a XML type column
  2. Created XSD Schema out of that XML file in SQL Server
  3. Now in SSIS, used XML Source and provided the XML schema for mapping to OLEDB destination.

But the execution failed saying

"Error: 0xC02090E7 at Load XML, XML Source 1: The component "XML Source" (1) was unable to read the XML data. DTD is prohibited in this XML document."

BOL says SSIS doesn't support DTD, and there is no way we can avoid DTD in my source file.

Please anyone help me to resolve this issue.

Here is my XML file:

Awaiting your kind response. Also let me know if need some other details to understand the scenario.

回答1:


Have you tried loading the raw XML into a XML data type in a database table and then converting the data into database tables via stored procedures? I generally prefer this method so that I can preserve the original XML code in case something changes in the schema that I am unaware of at the time of the import such as the source system adding new nodes to the file. If you go with this approach, then you could use sp_xml_preparedocument and OPENXML to convert the data. Please note OPENXML supports DTD to infer the output data types.




回答2:


In SSRS, this error can happen if there's a memory shortage. Don't know whether that goes for SSIS as well. (But you mention the large file explicitly, so perhaps it's relevant. You could try with a smaller file).

This link indicates you'll have to make your own workaround. Perhaps with some preprocessing of the XML file?
