For the pull parser call XmlEvCleanPPCtx() to release memory and structures used during the parse. The SAXSample program uses SAX APIs to show all lines in the play Cleopatra containing a given word. The following sample code fragment is from DOMNamespace.c: If threads fork off somewhere in the sequence of calls between initialization and termination, the application produces unpredictable behavior and results.
For example, suppose an ASCII document with an XMLDecl of encoding=ascii is blindly converted to EBCDIC. The package implements the SAX interface, which defines functions that receive notifications for SAX events. This package implements a single XML interface. SAX is not a W3C specification. However, you can register an error message callback at initialization time. Traverses the DOM and reports the number of elements, as shown in the following sample output: Specifies the output file of the XSLT processor. Simple API for XML (SAX). Could you give some indication of what platforms you are writing for? This section contains the following topics: The Oracle XML parser for C reads an XML document and uses DOM or SAX APIs to provide programmatic access to its content and structure. Thus, the application has more procedural control over XML processing. Example 18-8 Modifying a Database Document with the DOM API. Table 18-4 C XML Parser Command-Line Options. The namespace System.Xml would be the only additional namespace that we would be using. You can find the specification for the Second Edition at the following URL: The DOM Level 1, Level 2, and Level 3 specifications are W3C Recommendations. Element defines get and set functions for XML elements. This function would be equivalent to an OCIObjectNew() for other types. In particular, the DOM functions in Table 15-5 have dual APIs. This section contains a sample pull parser application, a document to be parsed, and a list of the events that the application generates from the document. Creating and destroying contexts.
Viewed 133k times 47. To use SAX, initialize an xmlsaxcb structure with function pointers and pass it to XmlLoadSax(). If you do not provide a default, then the application assumes UTF-8 on ASCII platforms and UTF-E on EBCDIC platforms. The *.std file contains the expected output for each program. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. You can control the XML encoding in the following ways: Specify a default encoding to assume for files that are not self-describing, Specify the presentation encoding for DOM or SAX. This XML parser is exactly what it says on the tin: rapid XML.
Fastest? Terminate the parsing process with XmlDestroy(). The make utility changes into each demo subdirectory and runs make to do the following: Compiles the C source files with the cc utility. Job interview adjustment request was ignored. The XmlEvGetTagUriID and XmlEvGetAttrUriID functions invoke this callback once to get the ID of the corresponding URI. You can also include a pointer to a user-defined context structure, which you pass to each SAX function. Function names begin with the string XmlSax. Register the callback functions. if you need a full bore parser, the above are almost required, xml is tricky. The program does not free memory allocated for parameters passed to the SAX callbacks or for nodes and data stored with the DOM parse tree until you call XMLFreeDocument() or XMLDestroy(). Perform the following steps in your application: Initialize the parsing process with the XmlCreate() function. Oracle Database XML C API Reference for the DOM, SAX, and callback APIs, http://www.oracle.com/technology/tech/xml/. Notation defines functions that get the system and public ID from a node.
