[opensuse-autoinstall] <match_type>regex</match_type> -- regex support?

21 Jan 2010

      I'm wondering *which* regex system is used here and what
the constraints on its use are.

    Google: [ autoyast "<match_type>regex</match_type>" ]

And there's precious few examples to work from.

The only official example shows:

    <rule>
        <board_vendor>
            <match>ntel</match>
            <match_type>regex</match_type>
        </board_vendor>
        <result>
            <profile>classes/largeswap.xml</profile>
            <continue config:type="boolean">true</continue>
            <dont_merge config:type="list">
              <element>partition</element>
            </dont_merge>
        </result>
    </rule>

and the value in the <match> element doesn't even have any
regex pattern, wildcard, classes, etc.
...
From this example, all i can infer is that a <match>
element value is used as a non-anchored match string.
("match anywhere")
I have seen another example showing the use of the
"^" begin-of-line anchor symbol

    e.g. "<match>^SUSE Linux Enterprise Server</match>".

But what is the full-extent of what i can use here?

for my needs right now, i'd like to use

   <product>PowerEdge [12]850</product>

to match the Dell PE 1850 and PE 2850 systems.  Will this
work?  (i imagine i may have to escape some patterns
to fit XML specification, which i'm not very familiar
with, but that's just a detail)

thanks,
