parser

The standardized nature of XML has given rise to a number of derivative cross-platform, cross-language parsers and derivative technologies.

Most parsers that implement the DOM provide at least a vendor-specific means of access to an underlying SAX parser.

Note that the form itself is nothing but an XML-based document and can be manipulated with the standard Java-based XML parsers.

Building your own parser increases the complexity of your application , and will not perform as well as the shipped parsers .

However, I still cannot work up a great deal of enthusiasm for the function docstring style of parsers.

As well, [xmlproc] provides a variety of high-level and experimental interfaces that other parsers do not.

XML parsers do not preserve white space within attribute values the same way that they preserve white space within element textual content .

RDFa parsers will retrieve the value from the text node of the element to which the property attribute is attached.

You can construct parsers that are optimized to use an in-memory representation of a given Schema for validation (as mentioned earlier).

Obviously, proper syntax is necessary for parsers to be able to accept XML documents at all.

In contrast to PLY or Spark, DParser itself is written in C, and is thus likely to be considerably faster than pure-Python parsers.

Indeed, given its prevalence in Python, Perl, and Apache projects, expat is clearly one of the most widely-used XML parsers available.

The heavy work of converting a reST text into a tree of nodes is done by the docutils. parsers. rst subpackage.

XML parsers will simply reject documents that do not use quotes around attribute values and report an error.

First, some number of copies of the document representations are built from parsers, with each resulting document object retained.

Most people will end up with XML 1. 1 Processors as they upgrade their parsers, just as all the Xerces users already did.

Conversely, the parsers that ship with development environments were tested with an eye towards compatibility.

The thesis introduced the software and hardware design proposal of CNC. The processing procedure parsers have been introduced weightily.

Their names are not allowed to contain colons, although parsers may not enforce that rule.

The potential for automated parsing with open-source validating parsers also influenced adoption of this guideline.

XML parsers can use this parent-child structure to navigate to a document, and even to modify the structure or content of the document.

Parametric parsers are a form of dynamic parsers that changes their behavior at run time based on some attribute or data.

For all of your parsers, the inputs are always the same: strings for the stock symbols.

We have the ability to translate from a number of parsers to an internal representation which we use for compilation.

With the ubiquity of XML, the VRML spec was rewritten to take advantage of XML parsers (and programmer familiarity with XML).

In our game we wanted to have separate parsers for the scripting language and the GUI descriptions, since they used different grammar rules.

Most formal parsers use variants on Extended Backus-Naur Form (EBNF) to describe the "grammars" of the languages they describe.

You can use these parsers at runtime to avoid the cost of constructing and deconstructing parsers when you need to parse a document.

You can specify the grammar caching parser configuration (org. apache. xerces. parsers. XMLGrammarCachingConfiguration).

XML parsers are designed so that any input (well-formed or not, valid or not) is handled in a defined way.

You can now validate the syntax in scripts with multiple database parsers, and run scripts serially against multiple database connections.

Nevertheless, the approach described here is not the way plug-in parsers were initially meant to be used.

Parsers can be used as conditions, as well. When the parser matches the condition is met.

Among these liberal parsers, we chose Mark Pilgrim's Feed Parser, as the target programming language was Python.

Second, a major purpose of JAXP is to provide vendor independence when dealing with parsers.

It is desirable to use a version mechanism that parallels the schema-discovery mechanism standardized for validating parsers.
