XPATH better way to parse xml - xpath

Question

What is the better way to parse such xml:
<FindLicensesResponse xmlns="http://abc.com">
<FindLicensesResult>
<Licensies>
<ActivityLicense>
<id>1</id>
<DateIssue>2011-12-29T00:00:00</DateIssue>
<ActivityType xmlns:s01="http://www.w3.org/2001/XMLSchema-instance" s01:type="ActivityType">
<code>somecode1</code>
</ActivityType>
<ActivityTerritory xmlns:s02="http://www.w3.org/2001/XMLSchema-instance" s02:type="Territory">
<code>somecode2</code>
</ActivityTerritory>
<ActivityLicenseAttachments />
</ActivityLicense>
<ActivityLicense>
<id>2</id>
<DateIssue>2011-12-21T00:00:00</DateIssue>
<ActivityType xmlns:s01="http://www.w3.org/2001/XMLSchema-instance" s01:type="ActivityType">
<code>somecode3</code>
</ActivityType>
<ActivityTerritory xmlns:s02="http://www.w3.org/2001/XMLSchema-instance" s02:type="Territory">
<code>somecode4</code>
</ActivityTerritory>
<ActivityLicenseAttachments />
</ActivityLicense>
</Licensies>
</FindLicensesResult>
I need to get values from each ActivityLicense: id, DateIssue and inner ActivityType: code and inner ActivityTerritory: code.
Now I do it like this:
CachedXPathAPI xpathAPI = new CachedXPathAPI();
Element nsctx = result.getSOAPPart().createElementNS(null, "nsctx");
nsctx.setAttributeNS("http://www.w3.org/2000/xmlns/","xmlns:el","http://abc.com");
NodeList activityLicenses = xpathAPI.selectNodeList(result.getSOAPPart(),"//el:ActivityLicense", nsctx);
for (int i = 0; i < activityLicenses.getLength(); i++) {
Node id = xpathAPI.selectSingleNode(activityLicenses.item(i), "//el:id", nsctx);
Node dateIssue = xpathAPI.selectSingleNode(activityLicenses.item(i), "//el:DateIssue",nsctx);
System.out.println("id: " + id.getTextContent());
System.out.println("dateIssue: " + dateIssue.getTextContent());
}
But I can't get values from ActivityType/code and ActivityTerritory/code
