A SAX parser only needs to report each parsing event as it happens, and normally discards almost all of that information once reported ( it does, however, keep some things, for example a list of all elements that have not been closed yet, in order to catch later errors such as end-tags in the wrong order ).

SAX and parser
* SAX — serial access parser API for XML, an alternative to DOM.
* Xerces – One of the original and most popular SAX and DOM parser.
SAX ( Simple API for XML ) is an event-based sequential access parser API developed by the XML-DEV mailing list for XML documents.
Thus, the minimum memory required for a SAX parser is proportional to the maximum depth of the XML file ( i. e., of the XML tree ) and the maximum data involved in a single XML event ( such as the name and attributes of a single start-tag, or the content of a processing instruction, etc.
Some implementations do not neatly fit either category: a DOM approach can keep its persistent data on disk, cleverly organized for speed ( editors such as SoftQuad Author / Editor and large-document browser / indexers such as DynaText do this ); while a SAX approach can cleverly cache information for later use ( any validating SAX parser keeps more information than described above ).
To validate this in a SAX parser, one must keep track of all ID attributes ( any one of them might end up being referenced by an IDREF attribute at the very end ); as well as every IDREF attribute until it is resolved.
While a SAX parser may well be used to construct such a tree initially, SAX provides no help for such processing as a whole.
A parser that implements SAX ( i. e., a SAX Parser ) functions as a stream parser, with an event-driven API.
This XML document, when passed through a SAX parser, will generate a sequence of events like the following:
Thus in the example above, a SAX parser may generate a different series of events, part of which might include:
* SAX parser in Python
* The QtXml module implements SAX and DOM interfaces to Qt's XML parser.
Expat's parsing events resemble the events defined in the Simple API for XML ( SAX ), but Expat is not a SAX-compliant parser.
SAX and only
STX only allows queries immediately surrounding the current node so it can quickly start transforming and outputting SAX event nodes as they arrive.
SAX and each
Where the DOM operates on the document as a whole, SAX parsers operate on each piece of the XML document sequentially.
SAX and parsing
* the Simple API for XML parsing interface or SAX interface
The event-driven model of SAX is useful for XML parsing, but it does have certain drawbacks.
SAX parsing is unidirectional ; previously parsed data cannot be re-read without starting the parsing operation again.
The library implements a number of standard APIs for XML parsing, including DOM, SAX and SAX2.
* XML creation and parsing through DOM and SAX
SAX and event
However, XML elements can contain many other XML objects, and so SAX represents them as does XML itself: by one event at the beginning, and another at the end.
Note that the first line of the sample above is the XML Declaration and not a processing instruction ; as such it will not be reported as a processing instruction event ( although some SAX implementations provide a separate event just for the XML declaration ).
SAX and all
The OMX Stockholm PI (), formerly known as SAX All Share, is a stock market index of all shares that trade on the Stockholm Stock Exchange.
SAX and information
Other tasks, such as sorting, rearranging sections, getting from a link to its target, looking up information on one element to help process a later one, and the like, require accessing the document structure in complex orders and will be much faster with DOM than with multiple SAX passes.
SAX and reported
The result above may vary: the SAX specification deliberately states that a given section of text may be reported as multiple sequential text events.
SAX and does
Properly speaking, the SAX interface does not deal in elements, but in events that largely correspond to tags.
SAX and some
Draw some conclusions: for example, the SGXB SAX J1818. 6-1703 was discovered by BeppoSAX in 1998, identified as a SGXB of spectral type between O9I − B1I, which also displayed short and bright flares and an unusually very low quiescent level leading to its classification as a SFXT.
SAX parsers have some benefits over DOM-style parsers.
SAX and for
* JDOM — a Java-based document object model for XML that integrates with DOM and SAX and uses parsers to build the document.
Choose which model seems to work best: for SAX J1818. 6-1703 the analysis best fits the model that predicts SFXTs behave as SGXBs with different orbital parameters ; hence, different temporal behavior.
SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model ( DOM ).
Unlike DOM, there is no formal specification for SAX.
The Java implementation of SAX is considered to be normative .. SAX processes documents state-dependently, in contrast to DOM which is used for state-independent processing of XML documents.
* SAX, a satellite for X-ray astronomy of the Italian Space Agency
* SAX ( Symbolic Aggregate approXimation ), a symbolic representation for time series
The Python programmability extension, introduced in SPSS 14, replaced the less functional SAX Basic " scripts " for most purposes, although SaxBasic remains available.
SAX and have
X-ray burst oscillations and quasi-periodic oscillations in addition to coherent X-ray pulsations have been seen from SAX J1808. 4-3658, making it a Rosetta stone for interpretation of the timing behavior of low-mass X-ray binaries.
SAX and such
This is as opposed to SAX which streams XML events such as " open element " " close element " " text node " ( and so on ) so that other software that can begin interpreting these immediately -- before the end of the file is reached.
Examples of such models include the XPath data model, the XML Infoset, and the models implied by the DOM and the events in SAX 1. 0.
SAX and ).
Circuits are collections of paths through which fragments of XML stream ( usually as SAX or DOM events ).
Similarly, the duchy's constitution refers to it in German as Herzogtum Warschau, and its coins bore the Latin inscription FRID · AVG · REX SAX · DVX VARSOV · ( Fridericus Augustus, Rex Saxoniæ, Dux Varsoviæ ; " Frederick Augustus, King of Saxony, Duke of Warsaw ).
