As you got the complete direction details in this already given that instruction i.e. called legs step. Try to get the value of node and description from the

<name>Head west</name>
<description>
    <![CDATA[go 250&#160;m]]>
</description>

this will given that step by step detail in each every node. Store this value as string in list array also you can get the direction symbol from the those node
