a character string containing the name of the XML file to parse
or an XML encoded object.
path
a vector or list of character strings containing one or more XML paths.
isFile
a logical value. If
TRUE, the argument
parse
is the name of a file containing the XML representation of an S-PLUS object.
Otherwise,
parse is the XML representation of
an object.
OPTIONAL ARGUMENTS:
default
a character string providing a default return value for invalid paths.
delimiters
a character string specifying the delimiter to use when
parsing.
separateDelimiters
a logical value. If
T, successive delimiters will create an empty value.
VALUE:
a named list of character vectors with one list element for each string
in the argument
path, where the names of the list
elements are the
path strings. Each list element
contain the parsed strings corresponding to a XML path string.
# Create an XML file for an S-PLUS matrix and parse with an XML path
xmlfile <- file.path(path.expand("~"), "statex91.xml")
createXMLFile(state.x91, xmlfile)
parseXMLPath(xmlfile, isFile=T, "S-PLUS/Matrix/RowNames/Items/Item/text()")
# Create an XML string for an S-PLUS matrix and parse with an XML path
xmls <- createXMLString(state.x91)
parseXMLPath(xmls, isFile = F,
"S-PLUS/Matrix/Columns/Column[@name = 'Population']/Items/Item/text()")
