I want to check the input attribute value with the point tokenized value

I was trying to see if the input attribute name and value exists in the Points/Point and check the Atn condition and use the sibling attripute name value of the points/point in the output xml. Here is the input xml

<Input>  
            <Att1>
            <attribute name="test1">11</attribute>
            <attribute name="test2">N/A</attribute>
            <attribute name="test3">2</attribute>
            <attribute name="test4">455</attribute>
            <attribute name="test5">16</attribute>
            </<Att1>



            <points>
            <point>
            <Atn>test1=11 | test1=12</Atn>
            <newName>test6</newName>
            <newValue>46</newValue>
            </point>
            <point>
            <Atn>test4!=16 | test4!=12</Atn>
            <newName>test8</newName>
            <newValue>7</newValue>
            </point>

            <point>
            <Atn>test4!=null</Atn>
            <newName>test9</newName>
            <newValue>6</newValue>
            </point>

            <point>
            <Atn>!test1</Atn>
            <newName>test5</newName>
            <newValue>6</newValue>
            </point>

            <point>
            <Atn>test3=4</Atn>
            <newName>test4</newName>
            <newValue>6</newValue>
            </point>

            <point>
            <Atn>test3!=40</Atn>
            <newName>test4</newName>
            <newValue>46</newValue>
            </point>


            </points>

        </Input>

Here is the xsl

    <xsl:variable name="testCondition"
        select="Atn" />
        message1:<xsl:value-of select="$testCondition"/>

        <xsl:variable name="conditionRules"
        select="str:tokenize($testCondition,'|,!,!=')" />

the expected output

        <output>  
            <Att1>
            <attribute name="test1">11</attribute>
            <attribute name="test2">N/A</attribute>
            <attribute name="test3">2</attribute>
            <attribute name="test4">455</attribute>
            <attribute name="test5">16</attribute>
            <attribute name="test6">46</attribute>
            <attribute name="test8">7</attribute>
            </<Att1>
        </output>
