accessing numerical attribute values

[John A. Mitchell]

I am a so-called newbie at this -- here goes.
I am trying to exract the value "double startTime" from the xml below.  
I have an "Element" but don't know
how to "decode" or "transcode" the attribute value into a "double"

<timeBlock>
<startTime value="0.336"/>
<timeIncrement value=".0003"/>
</timeBlock>
double getStarTimet(Element e){
         
           String startTime = new String("startTime");
           String value = e.getAttribute(startTime);
           double value = ????
           return value;
}

Also, when I print "value"; say like "System.out.println(value)" I get 
an empty string?
Can someone point me in the right direction here?

Here is the c++ that I have effectively used in the past (but now I need 
the Java):
double Jpp_ParsedValues::getDoubleAttribute(DOMElement* e, const char* 
name){

 // This function retrieves the value of the attribute "name" on the 
element
 const XMLCh* start = XMLString::transcode(name);
 const XMLCh* c =  e->getAttribute( start );
 delete start;

 char* s = XMLString::transcode(c);
 double value = atof(s);
 delete s;
 return value;
}
Now I need to do this in "Java" using xerces-j
I don't know where to look to figure this out.
