Duration functions work in the opposite direction. For example, you can use the hours-from-duration function on P2D to get 48 lt xsl variable name hours

Working with MSSOAP PythonXML

Tue, 20 Sep 2011 14:34:23 GMT

When working with MSSOAP, you have the option of using an RPC client or a Serialization client. The RPC client works essentially the same way that SOAPy does however, there are some subtle differences. For example, to initialize a connection with remote service description, use the mssoapinit method as opposed to SOAPy's get_proxy, but the net effect is the same as shown here sc response sc.methodName param, param Again, the net effect of web service RPC implementations is to allow you to work...

How to use Xalan XMLFundamentals

Wed, 14 Sep 2011 14:53:41 GMT

Xalan is a Java 1.1 character mode application. To use it, you'll need a Java 1.1-compatible virtual machine such as Sun's Java Development Kit JDK , or Java Runtime Environment JRE , Apple's Macintosh Runtime for Java 2.2 MRJ , or Microsoft's virtual machine. You'll need to set your CLASSPATH environment variable to include both the xalan.jar and xerces.jar files both included in the Xalan distribution . On Unix Linux you can set this in your .cshrc file if you use csh or tcsh or in your...

SOAP and WSDL XMLStandards

Mon, 12 Sep 2011 19:58:44 GMT

In the last chapter, you learned about web services and how they work toward enabling disparate systems to communicate. Of course, if everyone just chose their own formats in which to send messages back and forth, that wouldn't do much good in the interoperability area, so a standard format is a must. XML-RPC is good for remote procedure calls, but otherwise limited. SOAP overcomes that problem by enabling rich XML documents to be transferred easily between systems, even allowing for the...

Example DBMSXMLGEN Generating Complex XML Inputting User Defined Types For Nested XML Documents Oracle XML DB

Tue, 06 Sep 2011 12:41:04 GMT

When you input a user-defined type UDT value to DBMS_XMLGEN functions, the user-defined type is mapped to an XML document using canonical mapping. In the canonical mapping, user-defined type's attributes are mapped to XML elements. Attributes with names starting with are mapped to attributes of the preceding element. User-defined types can be used for nesting in the resulting XML document. For example, consider tables, EMP and DEPT To generate a hierarchical view of the data, that is,...

Creating the CGI Script PythonXML

Sat, 03 Sep 2011 14:34:38 GMT

The xslt.cgi script pulls the stylesheets together and coordinates the processing and updating of the XML on disk. While this application lets you edit and display XML in your browser, it only consists of a single CGI script and two XSL sheets. The source data that may constantly change is also stored on disk as XML. XSLT transformations can be done programmatically using the xml.xslt.processor.Processor class provided 4XSLT is installed, as shown earlier . When the CGI script launches, it...

The import precedence of a stylesheet module applies to all the top-level elements in that module, so for example the lt xsl template gt elements in module E have a higher import precedence than those in G. As lt xsl import gt statements must occur before any other top-level elements in a stylesheet module, the effect of these rules is that if each lt xsl import gt statement were to be replaced by the content of the module it imports, the top-level elements in the resulting combined stylesheet...

When selecting the results of a large column, you might want to retrieve only a portion of the result and create a URL to the column instead. For example, consider the case of a travel story Web site. If all the travel stories are stored in a table, and users search for a set of relevant stories, you do not want to list each entire story in the result page. Instead, you show the first 100 characters or gist of the story and then return a URL to the full story.This can be done as follows Example...

Configuring the UriFactory Package to Handle DBUris Oracle XML DB

Thu, 01 Sep 2011 18:55:40 GMT

The UriFactory, as explained in Creating Instances of UriType Objects with the UriFactory Package on page 12-25, takes a URL and generates the appropriate subtypes of the UriType to handle the corresponding protocol. For HTTP URLs, UriFactory creates instances of the HttpUriType. But when you have an HTTP URL that represents a URI path, it is more efficient to store and process it as a DBUriType instance in the database. The DBUriType processing involves fewer layers of communication and...

You can use the constants built in to the DOM to see what type of node you are dealing with. It may be an element, an attribute, a CDATA section, or a host of other things. All the node type constants are listed in Appendix D. To test a node's type, compare its nodeType attribute to the particular constant you're looking for. For example, a CDATASection instance has a nodeType equal to cdata_section_node. An Element with potential children has a nodeType equal to element_node. When traversing a...

Generating XML from Oraclei Database Using DBMSXMLGEN Oracle XML DB

Fri, 26 Aug 2011 12:22:55 GMT

DBMS_XMLGEN creates XML documents from any SQL query by mapping the database query results into XML. It gets the XML document as a CLOB or XMLType. It provides a fetch interface whereby you can specify the maximum rows and rows to skip. This is useful for pagination requirements in Web applications. DBMS_ XMLGEN also provides options for changing tag names for ROW, ROWSET, and so on. The parameters of the package can restrict the number of rows retrieved, the enclosing tag names. To summarize,...

A path expression is an expression that selects a set of nodes in the source tree. It defines an initial node-set, from which selection starts, and a sequence of steps which define navigation paths from the initial nodes to further nodes. The final result is the set of nodes reached by following each of the steps in turn. For example, the path from the initial nodes to further nodes. The final result is the set of nodes reached by following each of the steps in turn. For example, the path...

When you input a user-defined type value to SYS_XMLGEN , the user-defined type gets mapped to an XML document using a canonical mapping. In the canonical mapping the user-defined type's attributes are mapped to XML elements. Any type attributes with names starting with are mapped to an attribute of the preceding element. User-defined types can be used to get nesting within the result XML document. Using the same example as given in the DBMS_XMLGEN section Example 10-18, DBMS_XMLGEN Generating...
