Dom parser jar download

The build file defines the "targets" that you can use Ant to build. The batch and shell files set up the classpath and launch Ant with the target and any other arguments you provide. You can also set up your classpath manually see build. Main target where target is nothing for the default target or one of the following. If you build a target that depends on other targets, Ant creates those other targets in the correct order.

If you modify a sample and want to recompile it, you can run the Java compiler in the directory containing the example. Be sure xalan. To recompile and run the class files in the servlet subdirectory, the javax. These packages are available via the servlet. After recompiling a sample, you can use the jar utility to place your new. You can use Ant with the samples target to recompile the samples and place the unpackaged class files in xalansamples.

For more information, see Using Ant. To access previous releases, see the xalan-j archive directory. How do I view Xalan code in a browser? How do I download the latest development code to build myself?

The reason to use this distribution would be that you don't know which processor you are going to use, or might be using both. The reason to using this distribution is that you want more control. If you are using just the interpretive processor you can put xalan xalan.

Of course you can put both xalan. To use Xalan-Java, you need the following which are available from either a binary or source distribution: xml-apis.

The classes and methods used by the XSLT Processor to apply stylesheets are illustrated in the following diagram:. See Figure Namespaces are a mechanism to resolve or avoid name collisions between element types tags or attributes in XML documents. This mechanism provides "universal" namespace element types and attribute names whose scope extends beyond this manual. This enables an application to more easily identify elements and attributes it is designed to process.

The Java parser supports namespaces by being able to recognize and parse universal element types and attribute names, as well as unqualified "local" element types and attribute names. Validation involves checking whether or not the attribute names and element tags are legal, whether nested elements belong where they are, and so on.

XML documents are made up of storage units called entities, which contain either parsed or unparsed data. Parsed data is made up of characters, some of which form character data, and some of which form markup. Markup encodes a description of the document's storage layout and logical structure. XML provides a mechanism to impose constraints on the storage layout and logical structure.

A software module called an XML processor is used to read XML documents and provide access to their content and structure. It is assumed that an XML processor is doing its work on behalf of another module, called the application. This parsing process is illustrated in Figure Consider the following simple XML document:.

It provides classes and methods for an application to navigate and process the tree. In general, the DOM interface is most useful for structural manipulations of the XML tree, such as reordering elements, adding or deleting elements and attributes, renaming elements, and so on. The application deals with these events through customized event handlers.

Events include the start and end of elements and characters. Therefore, in general, SAX is useful for applications that do not need to manipulate the XML tree, such as search operations, among others. The preceding XML document becomes a series of linear events as shown in Figure This release supports binary compression of XML documents.

The compression is based on tokenizing the XML tags. The assumption is that any XML document has a repeated number of tags and so tokenizing these tags will give considerable amount of compression. Therefore the compression achieved depends on the type of input document; the larger the tags and the lesser the text content, then the better the compression.

The goal of compression is to reduce the size of the XML document without loosing the structural and hierarchical information of the DOM tree. The compressed stream contains all the "useful" information to create the DOM tree back from the binary format. The compressed stream can also be generated from the SAX events.

This is based on the assumption that XML files typically have repeated tags and tokenizing the tags compresses the data. The compression depends on the type of input XML document: the larger the number of tags, the less the text content, and the better the compression.

When a large XML document is parsed and a DOM tree is created in memory corresponding to it, it may be difficult to satisfy memory requirements and this could affect performance. This can be expanded at a later time into a DOM tree without performing validation on the XML data stored in the compressed stream. The compressed stream can be treated as a serialized stream, but note that the information in the stream is more controlled and managed, compared to the compression implemented by Java's default serialization.

The compression algorithm used is based on tokenizing the XML tag's. The assumption is that any XML file has repeated number of tags and therefore tokenizing the tags will give considerable compression.

A request for the XML tokens is registered using the setToken method. A few. The XSL stylesheet iden. Figure shows the main steps you need when coding with the DOMParser class:.

The examples represent the way we write code so it is required to present the examples with Java coding standards like all imports expanded , with documentation headers before the methods, and so on. See also Figure The following provides comments for Example The following example illustrates how to use DOMNamespace :. Applications can register a SAX handler to receive notification of various parser events.

This interface enables an application to set and query features and properties in the parser, to register event handlers for document processing, and to initiate a document parse. All SAX interfaces are assumed synchronous: the parse methods must not return until parsing is complete, and readers must wait for an event-handler callback to return before reporting the next event.

This interface replaces the now deprecated SAX 1. Table lists the class SAXParser methods. Figure shows the main steps for coding with the SAXParser class. It checks for well-formedness and validity.

Table lists oraxml's command line options. JAXP has a pluggability layer that enables you to plug in an implementation of a processor. Without it there is no way for the parser to know what to validate against. Do you have DTD caching? Answer : Yes, DTD caching is optional and is not enabled automatically.

The Java code has been loaded with loadjava and runs in the Oracle9 i server process. This will open. I am exporting Java objects to XML. However, I am unable to set the DTD of these documents. How do I set the DTD of the freshly constructed XML documents to use this one in order to be able to check the correctness of the documents at a later time? Answer : Your method of getting the DTD object is correct.

Here is a sample code to do that:. Is the parser case-sensitive as far as validation against DTDs go - or is it because, there is a namespace also in the tag definition of the element and when a element is defined along with its namespace, the case-sensitivity comes into effect?

Answer : XML is inherently case-sensitive, therefore our parsers enforce case sensitivity in order to be compliant. When you run in non-validation mode only well-formedness counts. Answer : Your DTD syntax is not valid. For example, your DTD contains:.

Is there a standard extension other than. As an example, the external entity is A. Currently we are using. Is there a standard extension that we should be using? Answer : The file extension for external entities is unimportant so you can change it to any convenient extension, including no extension. Answer : You can use the getElementsByTagName method that returns a node list of all descent elements with a given tag name. You can then find out the number of elements in that node list to determine the number of the elements in the particular tag.

It will then check whether the document is well-formed and optionally whether it complies with a DTD. It also provides methods to support DOM Level 1 and 2. Answer : If you check the DOM spec referring to the table discussing the node type, you will find that if you are creating an element node, its node value is null and hence cannot be set.

However, you can create a text node and append it to the element node. You can then put the value in the text node. Set the validation mode of the parser using setValidationMode. How do I efficiently obtain the value of first child node of the element without going through the DOM tree? Answer : If you do not need the entire tree, use the SAX interface to return the desired data. Since it is event-driven, it does not have to parse the whole document. Answer : The only current way of creating a doctype node is by using the parseDTD functions.

For example, emp. This method is used to extract contents from the tree or subtree based on the select patterns allowed by XSL. The optional second parameter of selectNodes , is used to resolve namespace prefixes that is, it returns the expanded namespace URL given a prefix. XMLElement resolves the prefixes based on the input document. You can use the NSResolver interface, if you need to override the namespace definitions.

The following sample code uses selectNodes. How does it get the value of the data? Answer : During a SAX parse the value of an element will be the concatenation of the characters reported from after the startElement event to before the corresponding endElement event is called. However, these methods are run.

Can you explain when they are called and from where? The parser reports parsing events directly through callback functions such as setDocumentLocator and startDocument. The application, in this case, the SAXSample, uses handlers to deal with the different events. Parser interface? Answer : You'll want oracle. The script executes the oracle. Edit this shell script for your environment before use. If your environment is set up correctly, then the UNIX shell script in Example generates version and usage information for the utilities in Table Note: A single period ".

After setting up the XDK for Java environment on Windows, you can use the command-line utilities described in Table The batch file executes the oracle. Edit the batch file for your environment before use. If your environment is set up correctly, then you can run the commands in Example at the system prompt to generate version and usage information for the utilities in Table To see which version of XDK you have installed, use javac to compile the Java code shown in Example The bin directory contains these components: orajaxb orapipe oraxml oraxsl transx The lib directory contains these JAR and ZIP files: classgen.
