XPath is a syntax for selecting parts of an XML document, similar to how file paths work in an operating system. It allows selecting elements, attributes, and text from an XML document. XPath uses paths containing axis, nodes, and predicates to navigate within an XML document. Common axes include child, parent, ancestor, descendant, following, and preceding. Functions, arithmetic expressions, and other features allow complex querying of XML documents.
XML (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It was designed to be simple, open, and extensible. Key features of XML include extensibility, separation of content from presentation, use of tags to denote hierarchies and relationships in data, and ability to validate documents. XML allows users to define their own tags to represent data for a given problem domain, providing more meaning and structure than HTML.
The document discusses various XML transformation languages including XSLT, XPath, and XQuery. It provides definitions and examples of how each works. XSLT is used to transform XML documents into other XML or XHTML documents using templates and XPath for navigation. XPath allows selecting nodes in an XML document. XQuery is used to query XML data similar to how SQL is used to query databases. Examples are given of XSLT and XQuery syntax and usage.
The document is an XQuery tutorial by Vyacheslav Zholudev that introduces the basics of XQuery including its type system, sequences, and using XPath expressions and FLOWR expressions to query XML documents. It provides examples of getting documents with doc(), selecting nodes with XPath, using predicates, LET clauses, FOR loops, and wrapping query results.
This document provides an introduction to querying XML documents using XPath and XQuery. It begins with an overview of XML and its tree structure. It then covers the basics of XPath, including path expressions and functions. XQuery is introduced as a more powerful query language that incorporates XPath and allows restructuring results. Examples are provided to demonstrate XPath and XQuery expressions for retrieving, filtering, joining, and aggregating data from XML documents. Built-in functions, sorting, and nested queries in XQuery are also discussed.
Displaying XML Documents Using CSS and XSLBình Trọng Án
XML documents can be displayed in different formats using style sheets. CSS is used to control visual properties like colors and fonts, while XSL is used to transform XML documents into other formats like HTML. XSL uses templates and patterns like sorting, filtering, and matching to transform XML. Selectors in CSS identify XML tags to which styles apply, and declarations specify property-value pairs to style those tags. Contextual selectors help differentiate between identical tags. Box model properties like margin, border, and padding position text blocks.
This document provides an overview of AJAX (Asynchronous JavaScript and XML) and how it differs from traditional web applications. It discusses how AJAX allows asynchronous data retrieval, improving interactivity and user experience by avoiding full page refreshes. It then covers how AJAX works by using the XMLHttpRequest object to make asynchronous requests in the background. Examples of popular AJAX-powered sites are given, and code snippets demonstrate how to make AJAX requests from JavaScript and handle responses.

This document shares a photo of a boy with a medical condition and encourages sharing the photo to spread kindness. It claims that seeing the boy smile despite his condition should inspire others to smile as well, and that sharing the photo won't negatively impact others' social media feeds. The document ends by wishing god's blessings.
