The XML Information Set (Infoset) defines an abstract data model for XML. This data model is broadly tree-based and models the structure and data found in XML documents: elements, attributes, character data, processing instructions and comments. What the Infoset does not provide is a way to define subsets of the nodes in a tree, which is where the XML Path Language (XPath) comes into the picture. XPath is, as its name suggests, a path based syntax that is used to define subsets of XML data trees. A given expression in XPath describes a set of nodes in an XML tree. Evaluating the expression produces those nodes as the result. In short, XPath is a query language for XML, allowing various nodes in a tree to be pulled out according to certain criteria. Such criteria include parent/child relationships with other nodes in the tree, nodes with particular textual or numeric values and elements having particular attributes attached to them. XPath is a useful tool in its own right in any XML... See less

ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or '@' or an action of some sort. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose. Below is the ASCII character table and this includes descriptions of the first 32 non-printing characters. ASCII was actually designed for use with teletypes and so the descriptions are somewhat obscure. If someone says they want your CV however in ASCII format, all this means is they want 'plain' text with no formatting such as tabs, bold or underscoring - the raw format that any computer can understand. This is usually so they can easily import the file into their own applications without issues. Notepad.exe creates ASCII text, or in MS Word you can save a file as 'text only' See less

elements. Such code can become quite involved and fragile if you aren’t very careful. As the code walks down the tree hierarchy, loading one child after the other, a single misplaced or misnamed element may cause the program to fail. If an element isn’t where it’s expected to be, the chain of method calls that gives directions to the desired elements will be broken. What’s needed is a way to specify which nodes a program needs without explicitly specifying how the program navigates to those nodes. XPath is a fourth generation declarative language for locating nodes in XML documents. An XPath location path says which nodes from the document you want. It says nothing about what algorithm is used to find these nodes. You simply pass an XPath statement to a method, and the XPath engine is responsible for figuring out how to find all the nodes satisfying that expression. This is much more robust than writing the detailed search and navigation code yourself using DOM, SAX, or JDOM. XPath... See less
