Parses an XML string, xmlstr, and returns the corresponding Jython variable v.



v = xml_parse(xmlstr,attswitch='on')



This is a non-validating parser. XML processing entries or comments starting with '<?' or '<!', are ignored by the parser.


Input Arguments

xmlstr            XML string, for example read from a file.


attswitch        optional, default='on':
'on' reads XML header attributes idx, size, type if present and interprets these to create the correct Jython data types.
'off' ignores XML element header attributes and interprets contents as strings.

Output Arguments

v                   Jython variable or structure.



This example shows how to define a simple XML string and parse it into a Jython variable. As the idx, type, and size attributes are defined, the resulting Jython data structure conforms to these specifications (list of size [1x2]).


xmlstr = '<root idx="1" type="double" size="1 2">3.1416 1.4142</root>'


from gdxml import *

V1 = xml_parse(xmlstr)

print V1


[3.1416, 1.4142]  % (type jclass org.python.core.PyList)


Again, setting the attswitch parameter to 'off' lets the parser ignore the attributes and the returned variable is interpreted as a string.


V2 = xml_parse(xmlstr,'off')

print V2


'3.1416 1.4142'   % (type jclass org.python.core.PyString)


Let's define a more complex data set in XML and convert it into a Jython data structure:


# Paste this assignment into a Python script and run it:


xmlstr = """








    <name>myProject Two</name>







v = xml_parse(xmlstr)

print v



   {'bytes': '10472',

    'date': '2004-09-13',

    'name': 'myProjectName'}},


   {'bytes': '9851',

    'date': '2004-09-13',

    'name': 'myProject Two'}}]
