XPath to return nodes

Question

XPATH problem with dom4j

I am using dom4j to overwrite a value in the XML. The XML looks like this:

<name color="blue" time="555555"> 
    <element1 param="1"> 
        <value>value1</value> 
        <value>value2</value> 
        <value>value3</value> 
    <element1> 
</name> 

<name color="blue" time="888888"> 
    <element2 param="1"> 
        <value>value1</value> 
        <value>value2</value> 
        <value>value3</value> 
    <element1> 
</name> 

I am trying to select nodes by:

SAXReader saxReader = new SAXReader();
Document document =  saxReader.read(xmlLocation);
List list= document.selectNodes("//element1/@color/[@time='555555']" );

but the list returns boolean(which is true in this case). I wanted to change all the 3 values where time="555555".

If I do:

List list= document.selectNodes("//element1/@time" );

It returns nodes.(attributes and elements) Isn't there a way to directly go to that node where time is 555555. please help.

Assuming the following well-formed document:

<names>
    <name color="blue" time="555555"> 
        <element1 param="1"> 
            <value>value1</value> 
            <value>value2</value> 
            <value>value3</value> 
        </element1> 
    </name> 
    <name color="blue" time="888888"> 
        <element1 param="1"> 
            <value>value1</value> 
            <value>value2</value> 
            <value>value3</value> 
        </element1> 
    </name> 
</names>

If you want all 'name' nodes with a time of 555555 then you'll need

//name[@time = '555555']

If you want all value nodes underneath name with a time of 555555 then you'll need

//name[@time = '555555']/element1/value
