WPKG has regular expression support for hosts defined in hosts.xml file.

You can view the exact syntax on this page: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/jscript7/html/jsjsgrpregexpsyntax.asp

Quick examples:

    <host name="b[0-9] " profile-id="profile" />

works for: b1, b10, b100 does not work for: bubu, b, x, x1, x10, x100

    <host name=". " profile-id="profile" />

works for *all* hosts - use with care (!), place at the bottom of hosts.xml

    <host name="b. " profile-id="profile1" />

works for "b10", "b11", "b12345" etc.

    <host name="b. " profile-id="profile2" />
    <host name="bronek1" profile-id="profile1" />
    <host name="bron. " profile-id="profile3" />

Normally, hosts are parsed from top to the bottom, except when the hostname is not a regular expression. So host "bronek1" will match "profile1", even though it also matches "b. " and "bron. " (which are regular expressions).

Note

The behaviour of regular expressions changed slightly in WPKG 0.9.7.

Previously, a host name:

    <host name="pc" profile-id="profile2" />

would match all hosts that contain "pc" in the name.

Now it matches "pc", and only "pc".

To match "pc001", "pc002", "pcABC", you have to use "pc. ".

The change was introduced to ease the maintenance of hosts.
