RE: Looking for best option

["Bruce Reynolds" <bruce@xxxxxxxxxxxxxxxx>]

Hi Scott,

I was viewing the value after it has been through the parser so now it make
sense why < and > had been converted.

I don't see any characters that are not in the base64 alphabet.  

Sorry I missed the return value on the base64_decode().  In this case it is
returning the same value as what is in the <IMAGESIZE> tag but I will change
my code to use the value returned from base64_decode().

I've attached the response from the soap call and the debug log.

Thanks again,
Bruce

If that were really the case, the parser WOULD parse it out, believe me it
would.  HOWEVER... the XML parser *will* convert the &lt; to < and the &gt;
to >.  So if you're checking this by looking at the 'value' 
parameter that's passed to your end handler, then indeed it will look like
<BASE64DATA>

That's why I asked you to check it in the httpapi_debug.txt file, and NOT in
the value parameter. :)

That's fine as long as your tests use images smaller than 64k.  I just want
to make sure the diff between working and failing in your tests don't come
from the image being chopped up.

Hopefully you get the idea.  Any characters that aren't in the base64
alphabet (A-Z a-z 0-9 + / =) need to be removed.  x'0D' and x'25' were just
likely examples... you need to remove everything besides the base64
alphabet.

Once again...  base64_decode() will RETURN the output length.  You don't
need to go to the extent of parsing the XML for it.  Just do:

    len = base64_decode( ... parameters here ...);


If that doesn't help, please call the service with http_url_post() (instead
of POST_XML) and send me the XML document you get from your provider.  (Send
it to me off-list if it contains sensitive information).  That would make it
a lot easier for me to help you.
