Windup rules: excluding files / logical operators in when condition

[avoigtma]

Trying to match some patterns in e.g. xml files and exclude certain files.

The <when> condition supports logical operators, but how do they work?

Example below does not work as expected.

As well, removing the <and>/<not> from the when part and attempting to

handle this using the regexp for the filenamepattern, I did not succeed.

Any ideas?

Thanks.

<rule id="myRule">

    <when>

        <and>

            <filecontent pattern="myPattern" filename="{namepattern}.xml" />

            <not>

                <file filename="pom.xml" />

            </not>

        </and>

    </when>

    <perform>

        <hint title="myRule: title" effort="1" category-id="mandatory">

            <message>...</message>

        </hint>

    </perform>

    <where param="namepattern">

        <!-- <matches pattern="((?!pom)(.*))"/> -->

        <matches pattern="(.*)"/>

    </where>

</rule>

Generally all when conditions have implicitly <and> by default so not required to have it there. And using <not> is negating not a condition but just that one, I would omit it and I think this should work for you

      <rule id="myRule">
            <when>
                <filecontent pattern="pathToRoot" filename="{pattern}.xml"/>
            </when>
            <perform>
                <hint title="myRule: title" effort="1" category-id="mandatory">
                    <message>Something was caught</message>
                </hint>
            </perform>
            <where param="pattern">
                <matches pattern="([^pom]*)"/>
            </where> 
        </rule>

manarh thanks for the hint !

your suggested pattern will not do it as it would filter our too much from the target filename (e.g. omit 'config.xml') but  the following seems to solve it.

<matches pattern="([^p]{1}.*|p[^o].*|po[^m].*)" />
