Can we have change a unicode string Type object to a Tuple type
object.. If so how ????
Why? Are you getting an error that makes you think that's a good idea?

Tuples are basically structs, unicode objects are strings. There is no
canonical way to convert them. Tell us more about the problem you want
to be solved, and we might help you better.

**********

I have to get few strings from an application(strings of different
languages..ex: korean,japanese,french etc.,). The data returned by the
application was in the format of the xml.
Hence I was using pyRXP to get the data. I was not able to get all the
strigs in different languages. Now I wanted to use pyRXPU to get all
the strings of that application.When Iam using pyRXPU iam getting the
following error.

Traceback (most recent call last):
File "D:\LanguageScripts\Screens.py", line 106, in
test_1_01_DoSomething
TitlenSoftkeyfn()
File "D:\LanguageScripts\EventLog_Screens.py", line 66, in
TitlenSoftkeyfn
titleBar = root.TitleBar.currentText
File "D:\LanguageScripts\XmlWrapper.py", line 35, in __getattr__
tagName, attrs, children, spare = child
ValueError: need more than 1 value to unpack

Here the child is of the format unicode..

When pyRXP is used it was of the format tuple... I was just trying to
find out if there is some way that I make this code work.

I don't know pyRXP and pyRXPU, and especially not how you use them.
Who's responsible for writing that "XmlWrapper.py"? He or she obviously
expected a tuple returned that was basically a DOM-tree (tag, attrs,
childs and something called spare)

But changing to pyRXPU seems to break the protocol here. But I can't
judge that without seeing more code.


Looks like the OP needs to RTFM. Here's an excerpt from an article by
David Mertz (http://www.ibm.com/developerworks/library/x-
matters29.html):
"""
pyRXP's tuple tree data structure

pyRXP (and RXP itself) uses an efficient, lightweight tree
representation of XML documents. Each node in a pyRXP tree is simply a
tuple of the form:

(tagname, attr_dict, child_list, reserved)


No specialized Python classes are used in the representation -- just
tuples, dicts, lists, and strings (and None in the reserved position).
Perhaps surprisingly, this form is adequate to represent all the
information in an XML document. The tagname is a straightforward
string; the attribute dictionary is a dictionary that maps attributes
to values, as you would expect. ***The child list is more subtle:
Strings can be interleaved with tuples in the list, indicating a mixed
content element.*** Moreover, an element that has no content is
represented by an empty child list, but a self-closed tag is
represented by None.
"""

"subtle" is not the word I would have used :-)
