First, look at what an XML schema is. A schema formally describes what a given XML document contains, in the same way a database schema describes the data that can be contained in a database table structure, data types. An XML schema describes the coarse shape of the XML document, what fields an element can contain, which sub elements it can contain, and so forth. It also can describe the values that can be placed into any element or attribute. A Note About Standards. DTD was the first formalized standard, but is rarely used anymore. XDR was an early attempt by Microsoft to provide a more comprehensive standard than DTD. This standard has pretty much been abandoned now in favor of XSD. XSD is currently the de facto standard for describing XML documents. There are two versions in use, 1. You have to dig quite deep before you notice the difference. An XSD schema is itself an XML document there is even an a XSD schema to describe the XSD standard. There are also a number of other standards, but their take up has been patchy at best. The XSD standard has evolved over a number of years, and is controlled by the W3. C. It is extremely comprehensive, and as a result has become rather complex. For this reason, it is a good idea to make use of design tools when working with XSDs See XML Studio, a FREE XSD development tool, also when working with XML documents programmatically XML Data Binding is a much easier way to manipulate your documents a object oriented approach see Liquid XML Data Binding. The remainder of this tutorial guides you through the basics of the XSD standard, things you should really know even if youre using a design tool like Liquid XML Studio. Elements. Elements are the main building block of any XML document they contain the data and determine the structure of the document. An element can be defined within an XML Schema XSD as follows lt xs element namex typey An element definition within the XSD must have a name property this is the name that will appear in the XML document. The type property provides the description of what can be contained within the element when it appears in the XML document. There are a number of predefined types, such as xs string, xs integer, xs boolean or xs date see the XSD standard for a complete list. You also can create a user defined type by using the lt xs simple type and lt xs complex. Type tags, but more on these later. If you have set the type property for an element in the XSD, the corresponding value in the XML document must be in the correct format for its given type. Failure to do this will cause a validation error. Examples of simple elements and their XML are below Sample XSDSample XMLlt xs element nameCustomerdob. Customerdob. 2. T1. Z. Customerdob lt xs element nameCustomeraddress. Customeraddress. London Road. Customeraddress lt xs element nameOrder. ID. typexs int lt Order. ID. lt Order. ID lt xs element nameBody. Body. a type can be defined as. Body The previous XSD definitions are shown graphically in Liquid XML Studio as follows The previous XSD shown graphically using Liquid XML Studio. The value the element takes in the XML document can further be affected by using the fixed and default properties. Default means that, if no value is specified in the XML document, the application reading the document typically an XML parser or XML Data binding Library should use the default specified in the XSD. Fixed means the value in the XML document can only have the value specified in the XSD. For this reason, it does not make sense to use both default and fixed in the same element definition. In fact, its illegal to do so. Customername typexs string defaultunknown. Customerlocation typexs string fixed UK. The previous XSD shown graphically using Liquid XML Studio. Cardinality. Specifying how many times an element can appear is referred to as cardinality, and is specified by using the min. Occurs and max. Occurs attributes. In this way, an element can be mandatory, optional, or appear many times. Occurs can be assigned any non negative integer value for example 0, 1, 2, 3. Occurs can be assigned any non negative integer value or the string constant unbounded, meaning no maximum. The default values for min. Occurs and max. Occurs is 1. So, if both the min. Occurs and max. Occurs attributes are absent, as in all the previous examples, the element must appear once and once only. Sample XSDDescriptionlt xs element nameCustomerdob. If you dont specify min. Occurs or max. Occurs, the default values of 1 are used, so in this case there has to be one and only one occurrence of Customerdoblt xs element nameCustomerorder. Occurs 0. max. Occursunbounded Here, a customer can have any number of Customerorders even 0lt xs element nameCustomerhobbies. Occurs2. max. Occurs1. In this example, the element Customerhobbies must appear at least twice, but no more than 1. The previous XSD shown graphically using Liquid XML Studio. Simple Types. So far, you have touched on a few of the built in data types xs string, xs integer, and xs date. But, you also can define your own types by modifying existing ones. Examples of this would be Defining an ID this may be an integer with a max limit. A Post. Code or Zip code could be restricted to ensure it is the correct length and complies with a regular expression. A field may have a maximum length. Creating you own types is coved more thoroughly in the next section. Complex Types. A complex type is a container for other element definitions this allows you to specify which child elements an element can contain. This allows you to provide some structure within your XML documents. Have a look at these simple elements lt xs element nameCustomer typexs string. Customerdob typexs date. Customeraddress typexs string. Supplier typexs string. Supplierphone typexs integer. Supplieraddress typexs string You can see that some of these elements should really be represented as child elements, Customerdob and Customeraddress belong to a parent element, Customer. By the same token, Supplierphone and Supplieraddress belong to a parent element Supplier. You can therefore re write this in a more structured way lt xs element nameCustomer. Type. lt xs sequence. Dob typexs date. Address typexs string. Type. lt xs element. Supplier. lt xs complex. Type. lt xs sequence. Phone typexs integer. Address typexs string. Type. lt xs element.

How to Programmatically Update an ODC File Shubh Raj Singh Share. Point dev blog. This post describes how to update ODC files programmatically by using either a Share. Point feature or a console application written in. Net code, or with a Power. Shell script. The contents pertain to Microsoft Share. Point Server 2. 01. Microsoft Share. Point Server 2. Excel Services. Microsoft SQL Server 2. Overview of Office Data Connection Files. An Office Data Connection ODC file contains connection information about how to connect to a data source and retrieve data for use in various documents such as Microsoft Excel workbooks. Connection information can either be stored in the workbook or in a connection file, such as an ODC file. Universal Data Connection UDC file. Typically, an ODC file is used while building Excel services reports that fetch data from a data source. As part of the implementation, this report can be deployed in multiple environments such as development, staging, test, and production. Each environment may have a different data source and hence a different connection string. The connection string should be changed in the ODC file as based on the environment it is deployed in. Usually this is a manual step however this task can be automated. This approach is the topic of this post. You can update ODC files programmatically by using either a Share. Point feature or a console application written in. Net code, or with a Power. Shell script. With the console application approach, files need to be published on the Share. Point site with some additional code or deployment steps which are not covered in this article. The Power. Shell approach takes care of uploading and publishing the ODC file to the Share. Point site. One ODC file can be used for one or more Excel files. ODC files contain the following types of information Connection string. Command Type. Command Text. SSO Application IDCredentials Method. Whether to always use the connection file. Description of an ODC File. An ODC file is a HTML file that contains embedded sections of XML. The XML in an ODC file determines the core connection information for the data source. This information includes Data provider specific connection string that is used to establish and open a connection to the data source. Query text that is used to fetch data. Name of the specific table or cube from which to fetch data. Hints about how the query text, cube, or table name is interpreted. Flag indicating that the ODC file is always used to connect to and query the data source as opposed to an application using a cached version of the data connection informationSpecific authentication information to use for the data source. If a server application is using the ODC file to fetch data, this information will often be used for connecting to the data sources.
