XML Document Parsing: Operational and Performance Characteristics
COMPUTING PRACTICES XML Document Parsing: Operational and Performance Characteristics Parsing is an expensive operation that can degrade XML processing performance. A survey of four representative XML parsing models—DOM, SAX, StAX, and VTD—reveals their suitability for different types of applications. Tak Cheung Lam roadly used in database and networking applications, the and Jianxun Jason Ding Extensible Markup Language is the de facto standard for the Cisco Systems interoperable document format. As XML becomes widespread, it is critical for application developers to understand the opera- Jyh-Charn Liu tional and performance characteristics of XML processing. Texas A&M University BAs Figure 1 shows, XML processing occurs in four stages: parsing, access, modification, and serialization. Although parsing is the most expensive operation,1 there are no detailed studies that compare • the processing steps and associated overhead costs of different parsing models, • tradeoffs in accessing and modifying parsed data, and • XML-based applications’ access and modification requirements. Figure 1 also illustrates the three-step parsing process. The first two steps, character conversion and lexical analysis, are usually invariant among dif- ferent parsing models, while the third step, syntactic analysis, creates data representations based on the parsing model used. To help developers make sensible choices for their target applications, we compared the data representations of four representative parsing models: document object model (DOM; www.w3.org/DOM), simple API for XML (SAX; www.saxproject.org), streaming API for XML (StAX; http://jcp.org/ en/jsr/detail?id=173), and virtual token descriptor (VTD; http://vtd-xml. sourceforge.net). These data representations result in different operational and performance characteristics. -
XML Parsers - a Comparative Study with Respect to Adaptability
XML Parsers - A comparative study with respect to adaptability Bachelor Degree Project in Information Technology Basic level 30 ECTS Spring term 2018 Johan Holm Mats Gustavsson Supervisor: Yacine Atif Examinator: Alan Said Abstract Data migration is common as information needs to be moved and transformed between services and applications. Performance in the context of speed is important and may have a crucial impact on the handling of data. Information can be sent in varying formats and XML is one of the more commonly used. The information that is sent can change in structure from time to time and these changes needs to be handled. The parsers’ ability to handle these changes are described as the property “adaptability”. The transformation of XML files is done with the use of parsing techniques. The parsing techniques have different approaches, for example event-based or memory-based. Each approach has its pros and cons. The aim of this study is to research how three different parsers handle parsing XML documents with varying structures in the context of performance. The chosen parsing techniques are SAX, DOM and VTD. SAX uses an event-based approach while DOM and VTD uses a memory-based. Implementation of the parsers have been made with the purpose to extract information from XML documents an adding it to an ArrayList. The results from this study show that the parsers differ in performance, where DOM overall is the slowest and SAX and VTD perform somewhat equal. Although there are differences in the performance between the parsers depending on what changes are made to the XML document. -

An Overview on Xml Parsing
International Journal of Advanced Computational Engineering and Networking, ISSN: 2320-2106, Volume-1, Issue-9, Nov-2013 AN OVERVIEW ON XML PARSING 1P.V.KALE, 2V.M.DESHMUKH Computer Science & Engineering Department, Prof. Ram Meghe Institute of Technology & Research, Badnera-Amravati. Email:[email protected],[email protected] Abstract: As XML has become a standard for data representation and exchange, XML data processing becomes more and more important for server workloads like web servers and database servers. Every application that processes information from XML documents needs an XML Parser which reads an XML document and provides interface for user to access its content and structure. One of the most time consuming part is data parsing. Parsing is a core operation performed before an XML document can be navigated, queried, or manipulated. Recently, high performance XML parsing has become a topic of considerable interest. In this paper, we are giving an overview on parsing and different available parsers in market today. We focus on a survey of four representative XML parsing models—DOM, SAX, StAX, and VTD—reveals their suitability for different types of applications. Keywords: XML, XML Parser, Parsing. I.

Java API for XML Processing
4 Java API for XML Processing THE Java API for XML Processing (JAXP) is for processing XML data using applications written in the Java programming language. JAXP leverages the parser standards SAX (Simple API for XML Parsing) and DOM (Document Object Model) so that you can choose to parse your data as a stream of events or to build an object representation of it. JAXP also supports the XSLT (XML Stylesheet Language Transformations) standard, giving you control over the pre- sentation of the data and enabling you to convert the data to other XML docu- ments or to other formats, such as HTML. JAXP also provides namespace support, allowing you to work with DTDs that might otherwise have naming conflicts. Designed to be flexible, JAXP allows you to use any XML-compliant parser from within your application. It does this with what is called a “pluggability layer”, which allows you to plug in an implementation of the SAX or DOM APIs. The pluggability layer also allows you to plug in an XSL processor, letting you control how your XML data is displayed. The JAXP APIs The main JAXP APIs are defined in the javax.xml.parsers package. That package contains two vendor-neutral factory classes: SAXParserFactory and 115 116 JAVA API FOR XML PROCESSING DocumentBuilderFactory that give you a SAXParser and a DocumentBuilder, respectively. The DocumentBuilder, in turn, creates DOM-compliant Document object. The factory APIs give you the ability to plug in an XML implementation offered by another vendor without changing your source code. The implementation you get depends on the setting of the javax.xml.parsers.SAXParserFactory and javax.xml.parsers.DocumentBuilderFactory system properties.
