using xpath need to get to a child and get another node one level up

I am trying traverse through an XML with XPath. I want to visit /group/isRequired[text()='Optional'] and travel one level up to grab the /bool node

I tried a few things like the below but can't seem to get it rit... appreciate any inputs.

I basically want to verify the Library node, group+isRequired node and the bool nodes in one statement.

//root/sample[library[text()='2']]/group/isRequired[text()='Optional']//bool[text()='true']
//root/sample[library[text()='2']]/group/isRequired[text()='Optional']../bool[text()='true']
//root/sample[library[text()='2']]/group/isRequired[text()='Optional']/bool[text()='true']
//root/sample[library[text()='2']]/group/isRequired[text()='Optional']/../bool[text()='true']


<root>
<sample>
    <id>1</id>
    <library>2</library>        
    <ruleName>Default</ruleName>        
    <group>
        <groupID>1</groupID>
        <groupName>orange</groupName>
        <isRequired>Optional</isRequired>           
    </group>
    <variant>1</variant>
    <bool>true</bool>
</sample>
</root>

You can go a different route, by filtering sample node by group/isRequired child, then you can continue from that sample node to get to the bool node :

//root/sample[library='2' and group/isRequired='Optional']/bool[.='true']

Simpler:

/root/sample[library = "2" and group/isRequired = "Optional" and bool = "true"]

You don't have to use /text() to get the value of every node in the XPath. Depending on whether you XML has a schema, you don't need to put the literal values in quotes. Without it, everything is a string value, so I put them in quotes just for safety.

You need to move two steps up:

/root/sample[library[text()='2']]/group/isRequired[text()='Optional']/../../bool[text()='true']

But is much cleaner to put multiple conditions in one predicate:

/root/sample[library[text()='2'] and group/isRequired[text()='Optional'] and bool[text()='true']]
