First the Data access mode is selected for this example use an actual file location, but XML File from variable or XML data from variable can also be selected. This screen is where some of the decision making must take place and also where many problems surface.

Also, rename the package to a descriptive name.ĭouble click on the XML Source to browse to the location of the XML file as shown below. Be sure to name the new solution and project appropriately as shown below. The SSIS import process starts with creating a new SSIS solution and project in SQL Server Data Tools (SSDT formerly known as BIDS or Business Intelligence Design Studio). Thus, an XML file is often self defining although special files called XML Schema Definition files (XSD) can also be used to validate, format, and describe a particular XML file.

Also, XML files are all about the information and data within a file and not about how to display the data or information. Furthermore, and contrary to HTML, each tag is not predefined, but is established by the users who generates the files. Just like HTML, XML and XML files use tags in XML's case, these tags are used to define, describe, structure, and nest data. First, an XML file is an extensible Markup Language file XML itself is a Markup Language which shares some similarities to HTML. XML files are no exception to this statement as Integration Services can load various XML files at various levels of complexity.īefore we dive into the load process, we need to cover a few basics about XML files. The ID in these examples is just a counter, or a unique identifier, to identify the different notes in the XML file.SSIS is a robust and versatile ETL tool that can handle most any type of load process that it is tasked with completing. These ID references can be used to access XML element in much the same way as the NAME or ID attributes in HTML. Sometimes I assign ID references to elements in my XML documents. My rule about not using attributes has one too: Use attributes only to provide information that is not relevant to the reader. What I’m trying to say is that you should use elements to describe your data. If you start using attributes as containers for XML data, you might end up with documents that are both difficult to maintain and to manipulate. attribute values are not easy to test against a DTD.

attributes are more difficult to manipulate by program code.attributes can not describe structures (like child elements can).attributes are not expandable (for future changes).attributes can not contain multiple values (elements can).Why should you avoid using attributes? Should you just take my word for it? These are some of the problems using attributes: A date attribute is used in the first, a date element is used in the second, and an expanded date element is used in the third: The following three XML documents contain exactly the same information. Here is another example, demonstrating how elements can be used instead of attributes. My experience is however that attributes are handy in HTML, but in XML you should try to avoid them, as long as the same information can be expressed using elements.

There are no fixed rules about when to use attributes to describe data, and when to use elements. Both examples provides the same information to the reader.

In the first example sex is an attribute. Take a look at these examples: Using an Attribute for sex:

Did you understand it now? Anyway, in the example above, the person id is a counter value that is irrelevant to the reader, but important to software that wants to manipulate the person element. Did you understand that? Here is another way to express that: Often attribute data is more important to the XML parser than to the reader. Usually, or most common, attributes are used to provide information that is not a part of the content of the XML document. The SRC attribute provides additional information about the element.Īttributes are always contained within the start tag of an element. In this HTML example SRC is an attribute to the IMG element. From HTML you can remember this construct. XML attributes are normally used to describe XML elements, or to provide additional information about elements.
