Finding an XML node by its attribute value and updating in Java

Question

Let's say I have the following XML document:

<Offices>
  <Office name="P">
    <Counter>1000</Counter>
  </Office>
  <Office name="K">
    <Counter>1006</Counter>
  </Office>
</Offices>

With that document I need to perform the following in Java:

1. Parse the XML.
2. Get the value of Counter given a certain value for a name attribute.
3. Update the XML with a new value for Counter for exactly this Office.

For 2. I have considered using XPath but editing/updating the XML seems to be not that easy this way.

How could I go through the XML finding a certain office name and update its counter? The XML itself won't be large, only something like 20 office entries max.
