Decoding for XML

A NotificationContentList can include multiple values. If a NotificationContentList includes multiple values, each value must be concatenated into one string when decoding. For example, after concatenating the following values, the string is abcdef:

<NotificationContentList>
  <value>abc</value>
  <value>def</value>
</NotificationContentList>

The following code shows an example NotificationContentList:

<NotificationContentList>
 <value>H4sIAAAAAAAAAEVOSQ7CMAz8SpRzi5ImbZO+gw+YLFDRjTo5IMTfcReJ28x4Fn84JkgZeccFL7ib\0d\
0afSBYaSE2OgZEuG8KEXApw/CXlowP5iEBY2lmrxxyYMs6OzIEzzC7DcU8DG8KryEe3RMJBU8rTNh7\0d\
0aaql1E4WS2rY2asLggraNttoa42+qpmzqx/0pIU0p2lJWV9l0ynZSXURbH+WnR5z2BM8wETda7Xdc\0d\
0a5gnP9e8PQPK8vfQAAAA=\0d\0a</value>
</NotificationContentList>

To decode the NotificationContentList, you must complete the following:

1. Concatenate the content of the values into one string.
2. Replace string \0d\0a with a new line.
3. Do a Base64 decode.
4. Do a Gzip decode.

For example, to view the compressed field values in the list, save the values to a file (in this case, values.txt) and use the following command to decompress the values, decode the values, and do a global line ending replacement:

cat value.txt | sed -e 's/\\0d\\0a/\n/g' | base64 --decode |
				  gzip -d

After decoding the NotificationContentList shown above with this command, the following content is saved to value.txt:
