SAXParser sp = spf.newSAXParser(); In this section, we are creating a reference to a Parser that will be used to actually parse the XML document. To do this we use the static factory method SAXParserFactory.newInstance(), which obtains a new instance of a SAXParserFactory. Once we[r]
The Monet system partitions the XML data into a set of tables corresponding to the different paths. This distributes the children of a node into different tables, and determining the children of a node requires a number of joins. The Monet and XRel systems store the byte range of each
Tip Use sp_executesql whenever possible when executing dynamic queries, because the plan has a better chance of being reused. Sometimes the dynamic query is very long and it becomes illegible. In these cases, you can use a variable to store the entire string and then use this variable as the[r]
parser.parse(uri); } Create a Parser object Now that we’ve asked our instance of saxOne to parse and process our XML document, it first creates a new Parser object. In this sample, we use the SAXParser class instead of DOMParser . Notice that we call two more methods,
The XML file for the following example, called “bookstore.xml”, is found in Example 18.10. 3 If you are not familiar with XML, this file is a good example of how the markup is structured. The Ajax program (Example 18.11) makes a request to the server to get the XML fil[r]

A plain OPML file, saved as an .xml file, can be viewed through the native XML parsers of IE5+ and NN6. These parsers automatically render XML tags in the same hierarchical fashion as OPML encourages outlines to be structured. But such ren- dering is under strict control of the[r]
However, defining redundancy is not quite so straightforward as might first ap- pear. The most obvious approach is, given a relation r and a FD A → B and two tuples t1 and t2 , to define a value t1 [ B ] to be redundant if t1 [ B ] = t2 [ B ] and t1[ A ] = t2[ A ]. While this definition is fine for F[r]
While you are in the header, you need to add a method that will start parsing the XML. You will call this method once you are fi nished loading the URL from the web site. Call the new method parseXML : - (void) parseXML; Instead of just logging the results, you can show the output o[r]

Although XPath is technically a subset language of the XSL initiative, most often people do not identify it with XSL because its range of use has widened so considerably since its inception. XPath is designed to be used with other XML technologies. XPath is integral to XSLT and XQuery. XPa[r]

Interoperability Between Web Services Web Services are interoperable at the network level. The implementation of a Web Service is completely independent of the operating system or the technology used to implement the service, and the description of the Web Service is encapsulated in an
Như các bạn đã biết XML là một ngôn ngữ tuyệt vời để mô tả và lưu trữ dữ liệu. Tuy nhiên với tốc độ phát triển của công nghệ thông tin, nhu cầu của các ứng dụng không chỉ dừng lại ở mức lưu trữ, các hệ thống cần trao đổi thông tin với nhau. Để trao đổi thông tin trong các tài liệu XML, người ta cần[r]
All those text nodes If you go through a detailed listing of all the nodes returned by the parser, you’ll find that a lot of them are pretty useless. All of the blank spaces at the start of the lines at the left are Text nodes that contain ignorable whitespace characters.
