The issues that are being encountered here are that XML has some special characters that need to be encoded in order for parsing to work correctly. Namely, these are the '&','<', '>', '"', and ''' characters. The URLEncoder class is meant to perform URL encoding and decoding which has a different set of special characters. The URLEncoder rules for encoding are as follows: The ASCII characters 'a' through 'z', 'A' through 'Z', '0' through '9', and ".", "-", "*", "_" remain the same.
The space character ' ' is converted into a plus sign '+'. All other characters are converted into the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the lower 8-bits of the character. As you can see, the space character is converted by the URLEncoder to a '+' which then would not get decoded back to a space by the JavaScript XML functions. I suppose the proper thing to do on the server side is to use an XML encoding method rather than the URLEncoder method. -Richard --- [EMAIL PROTECTED] wrote: > Thank you Gareth, Frank and Richard.
