XML has a number of related technologies that combine these technologies to give full play to the powerful capabilities of XML. These technologies include: XLink and XPointer (hyperlinks to set XML), DOM (Document Object model: File objects models, accessing, manipulating the contents of files), namespaces (solving problems with different elements having the same name), XHTML (next-generation HTML), and so on.XLink and XPointerIn the XML
XPath is a language used to select parts of an XML document. XPath is designed for XSLT, XQuery, and XPointer. XPath is a language used to select parts of an XML document. XPath is designed for XSLT, XQuery, and XPointer. XML teaches XPath to be a language used to select components of XML documents. XPath is designed for XSLT, XQuery, and XPointer.

(1) Introduction:XPath is a language for finding information in an XML document, and XPath can be used to traverse elements and attributes in an XML document.XPath is the main element of the XSLT standard, and XQuery and XPointer are built on top of the XPath expression at the same time.Therefore, the understanding of XPath is the foundation of many advanced XML applications.XPath is the XML Path language, which is a language used to determine the loc
XLink defines a standard way to create hyperlinks in an XML document.XPointer allows these hyperlinks to point to more specific parts (fragments) in an XML document.XlinkXLink is an abbreviation for the XML link language (XML linking Language)XLink is the language used to create hyperlinks in an XML documentXLink is similar to HTML links-but more powerfulAny element in an XML document can be a XLinkXLink supports easy links, as well as extended links to link multiple resources togetherLinks can
extract the data we need from a defined XML document, form different forms, XML, HTML, and various script.
About XPointer and Xlinks
Similar to Hyper Link in HTML. XPointer and XLink are used to join parts of other XML documents and other XML documents, where XPointer is equivalent to the anchor used in HTML to locate HTML content! But the level of connectivity
The XML schema works like a DTD. But the difference is that the schema file describes the specific type of elements and attributes in the XML file that references it. In addition, because it is written in XML, schemas and DTDs compare with the following advantages:
· The XML schema content model is open and can be expanded at will, and the DTD cannot parse the expanded content.
· A DTD can only define a content type as a string, whereas an XML schema allows content types to be defined as intege

In the process of compiling Ubuntu 12.04, it is often found that the ubuntu9.10 can compile the program in the 12.04 compiler does not pass, reported "undefined reference toxxxxx" error, as shown in the following figure:

language, the link capability of XML is very important. XML links and addressing mechanisms include XLink, XPath, and XPointer. XLink provides powerful link methods to establish one-way or multi-direction complex links between documents, as well as annotation links, summary links, extended link sets, and other link functions. XPath is used in XSLT and XPointer. it supports locating relative nodes and node

A DTD can only define a content type as a string, whereas an XML schema allows a content type to be defined as Integer, float, Boolean, or many other simple data types.
XML Schema uses namespaces to associate a particular node in a document with a schema, an XML file can have multiple schemas, and an XML file can have only one DTD.
