strange behaviour of colon within string

[khany]

hello all,

i am relatively new to python and i am trying to convert a php app i
have over to it using googleapps.

anyway here is the problem. i poll ebay API which has in its XML "<?
xml version="1.0" encoding="utf-8"?><findItemsAdvancedRequest
xmlns="http://www.ebay.com/marketplace/search/v1/services"> .... "

however it fails to create the string UNLESS i remove the colon ) in
the http section. i tried to substitute it with chr(58) but it errors
the same without showing why. does anyone know what i am doing wrong?
is this peculiar to googleapps?

thanks

Please show us code & actual stacktraces. Python can generate XML just fine,
so it's pretty likely that you are doing something wrong.

Could you please elaborate on "fails to create the string", preferably
in the form of a traceback. It might also help us if we knew what
behaviour you expected or what do you mean by "i remove the colon" .

OK

first thanks for replying so soon (most other groups out there take
days)

here is the code

========
xml = '<?xml version="1.0" encoding="utf-8"?> \
<findItemsAdvancedRequest xmlns="http://www.ebay.com/marketplace/
search/v1/services"> \
<categoryId>%(category)i</categoryId> \
<keywords>%(searchtext)s</keywords> \
<paginationInput> \
<pageNumber>%(page)i</pageNumber> \
<entriesPerPage>10</entriesPerPage> \
</paginationInput> \
</findItemsAdvancedRequest>' % \
{'category':9834, 'searchtext':"bmw", 'page':1}
print xml
========

if i run this, the page is blank (even the source) with no errors or
anything. if i remove the colon from the string (after the http) it
prints the string on the browser fine.

you can use a tri-quote string or make sure all lines end with \:
xml1 = """<?xml version="1.0" encoding="utf-8"?>
<findItemsAdvancedRequest xmlns="http://www.ebay.com/marketplace/\
search/v1/services">
<categoryId>%(category)i</categoryId>
<keywords>%(searchtext)s</keywords>
<paginationInput>
<pageNumber>%(page)i</pageNumber>
<entriesPerPage>10</entriesPerPage>
</paginationInput>
</findItemsAdvancedRequest>""" % \
{'category':9834, 'searchtext':"bmw", 'page':1}

xml2 = '<?xml version="1.0" encoding="utf-8"?>\n\
<findItemsAdvancedRequest xmlns="http://www.ebay.com/marketplace/\
search/v1/services">\n\
<categoryId>%(category)i</categoryId>\n\
<keywords>%(searchtext)s</keywords>\n\
<paginationInput>\n\
<pageNumber>%(page)i</pageNumber>\n\
<entriesPerPage>10</entriesPerPage>\n\
</paginationInput>\n\
</findItemsAdvancedRequest>' % \
{'category':9834, 'searchtext':"bmw", 'page':1}

print xml1

StarWing,

The triple String works a treat thanks. Not sure what the colon issue
was though. Now im getting Unsupported verb errors but thats an ebay
API issue i can work with.

Thanks to all for your help

The original version worked fine in Python 2.6.2, once I combined the
line that the email/listserver split for us. I also don't know what the
colon issue was; I suspect some other change happened at the same time
you changed the colon.

I also recommend the triple quote, for a few reasons. It avoids the
risk that you'll forget one of the trailing backquotes. It avoids the
risk of having an extra space after the backquote (most editors don't
show the spaces, I insist on visible whitespace). And it lets you make
the resulting string readable in source form.

However, for long strings, I strongly recommend you not combine the
string assignment with the % formatting logic. So I'd use a couple of
lines, something like:

format_string = """This
is
my formatted
string %(formatfield)
with some indentation preserved"""
xml = format_string % (.....)

You should consider running the program locally, and redirect the output
into a text file. Then you can examine exactly what's being produced.
Sometimes the browser adds its own surprises. I don't know anything
about the googleapps constraints.
