Nude cheerleaders chat - Validating the xml

In practice, details vary, but the overall model is the same.

Many parsers, for example, return separate text events for numeric character references.

Tools category section below includes annotated links to Web authoring / HTML editors, reviews, and other resources, along with links to HTML reference charts, cleanup and conversion tools, automated HTML tools, and HTML validators. Note that some tools include HTML editors will generate the HTML markup for you, such as Dreamweaver and Front Page above, and so will publishing programs and content management systems (CMS).

Virtually any kind of XML validation requires access to the document in full.

The most trivial example is that an attribute declared in the DTD to be of type IDREF, requires that there be an element in the document that uses the same value for an ID attribute.

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.). A DOM parser, in contrast, has to build a tree representation of the entire document in memory to begin with, thus using memory that increases with the entire document length.

This takes considerable time and space for large documents (memory allocation and data-structure construction take time).

Given the following XML document: 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).

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 parsing is unidirectional; previously parsed data cannot be re-read without starting the parsing operation again.
