Package gavo :: Package votable :: Module parser

Module parser

Stream parsing of VOTables.

This module builds on a shallow wrapping of expat in utils.iterparse. There is an "almost-tight" parsing loop in the parse method. It builds an xmlstan tree (mainly through the _processNodeDefault method).

Classes
	IGNORE this is a sentinel element used when an element is not known but robust parsing is requested.

Functions

parse(inFile, watchset=[], raiseOnInvalid=True)
returns an iterator yielding items of interest. source code

readRaw(inFile)
returns a V.VOTABLE instance with filled-in data for the input from inFile.

source code

parseString(string, watchset=[], raiseOnInvalid=True)
returns an iterator yielding pairs of (table definition, row iterator). source code

Variables
	DEFAULT_WATCHSET = `[]`
	VOTABLE_NAMESPACES = `['http://www.ivoa.net/xml/VOTable/v1.0', ...`
	computeEndProcessors = `utils.CachedGetter(_computeEndProcessor...`
	computeElements = `utils.CachedGetter(_computeElementsImpl)`
	__package__ = `'gavo.votable'`

Function Details

parse(inFile, watchset=`[]`, raiseOnInvalid=True)

source code

returns an iterator yielding items of interest.

inFile is a something that supports read(bytes)

watchset is a sequence of items of VOTable you want yielded. By default, that's just VOTable.TABLE. You may want to see INFO or PARAM of certain protocols.

parseString(string, watchset=`[]`, raiseOnInvalid=True)

source code

returns an iterator yielding pairs of (table definition, row iterator).

string contains a VOTable literal.
