|
Uses TokeParser to extract group information from the |
|
XML used to describe course groups. |
|
|
|
Input: |
|
Scalar containing XML (as retrieved from &lonnet::get_coursegroups). |
|
|
|
Output: |
|
Hash containing group information as key=values for (a), and |
|
hash of hashes for (b) |
|
|
|
Keys (in two categories): |
|
(a) groupname, creator, creation, modified, startdate,enddate. |
|
Corresponding values are name of the group, creator of the group |
|
(username:domain), UNIX time for date group was created, and |
|
settings were last modified, and default start and end access |
|
times for group members. |
|
|
|
(b) functions returned in hash of hashes. |
|
Outer hash key is functions. |
|
Inner hash keys are chat,discussion,email,files,homepage,roster. |
|
Corresponding values are either on or off, depending on |
|
whther this type of functionality is available for the group. |
