Кратък курс в XML (Extensible Markup Language ) Основни цели - XML 1. 0 Recommendation (http: //www. w 3. org/TR/2000/REC-xml-20001006#sec-origin-goals): 1. XML shall be straightforwardly usable over the Internet. 2. XML shall support a wide variety of applications. 3. XML shall be compatible with HTML. 4. It shall be easy to write programs which process XML documents. 5. The number of optional features in XML is to be kept to the absolute minimum, ideally zero. 6. The XML design should be prepared quickly. 7. The design of XML shall be formal and concise. 8. XML documents shall be easy to create. 1. 2. 3. 4. 5. 6. Няма семантика, нито набор тагове; метаезик; има 1 основен елемент - корен; всеки отворен таг следва да се затвори; част от осн. елемент не може да е включена в друг елемент на документа; всеки елемент може да има атрибути, които се явяват само веднаж; за всеки ел. отварящият и затварящ таг са на едно ниво. tag се дефинира в DTD чрез елемент: <!ELEMENT name type>

XML инф. в WEB документ) validating parser can use a DTD or schema to verify that a document is properly constructed A non-validating parser only requires that the document be wellformed. В tree-based parsing с DOM, документът се проверява за well-formed и валиден. parser го преобразува в дърво с 1 root node ( document object instance). След като document object tree е създадено, с използване интерфейси в API на DOM можете да модифицирате, изтривате и създавате клони и листа.
Кратък курс в XML (Extensible Markup Language ) Интерфейси на DOM
Кратък курс в XML (Extensible Markup Language ) Други DOM интерфейси са: Attr; Comment; Document; Node. List; Element; Document. Type; Entity; Text и др.
Кратък курс в XML (Extensible Markup Language ) Stream-Based Parsing with SAX (Simple API for XML) Недостатък на DOM е обработката на големи файлове – целият файл в паметта. SAX parsers четат последователно и генерират events. The Behavior of a SAX Parser За разлика от DOM и дърветата, SAX няма default object model. Рarsers чете XML document и “ fire events” когато: • отваря нов елемент • затваря елемент • #PCDATA и CDATA секции • обработва декларации на instructions, comments и entity
