Groovy Xml Parsing with namespaces - groovy

Question

I've been trying to do some xml modifications with groovy's XML Slurper.
Basically, i'm going through the xml and looking for tags or attributes that have ? as the value and then replacing it with some value.
I've got it working for xml that doesn't have namespaces but once I include them things get wonky. For example, this:
String foo = "<xs:test xmlns:xs="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:foo="http://myschema/xmlschema" name='?'>
<foo:tag1>?</foo:tag1>
<foo:tag2>?</foo:tag2>
</xs:test>";
produces:
<Envelope/>
Here's the groovy code I'm using. This does appear to work when I am not using a namespace:
public def populateRequest(xmlString, params) {
def slurper = new XmlSlurper().parseText(xmlString)
//replace all tags with ?
def tagsToReplace = slurper.depthFirst().findAll{ foundTag ->
foundTag.text() == "?"
}.each { foundTag ->
foundTag.text = {webServiceOperation.parameters[foundTag.name()]}
foundTag.replaceNode{
"${foundTag.name()}"(webServiceOperation.parameters[foundTag.name()])
}
}
//replace all attributes with ?
def attributesToReplace = slurper.list().each{
it.attributes().each{ attributes ->
if(attributes.value == '?')
{
attributes.value = webServiceOperation.parameters[attributes.key]
}
}
}
new StreamingMarkupBuilder().bind { mkp.yield slurper }.toString()
}

from groovy documentation
def wsdl = '''
<definitions name="AgencyManagementService"
xmlns:ns1="http://www.example.org/NS1"
xmlns:ns2="http://www.example.org/NS2">
<ns1:message name="SomeRequest">
<ns1:part name="parameters" element="SomeReq" />
</ns1:message>
<ns2:message name="SomeRequest">
<ns2:part name="parameters" element="SomeReq" />
</ns2:message>
</definitions>
'''
def xml = new XmlSlurper().parseText(wsdl).declareNamespace(ns1: 'http://www.example.org/NS1', ns2: 'http://www.example.org/NS2')
println xml.'ns1:message'.'ns1:part'.size()
println xml.'ns2:message'.'ns2:part'.size()
