Add the following parameter to your report after the xmlString parameter. The XML_INPUT_STREAM parameter is used by the xPath query executer as input source.
<parameter name="XML_INPUT_STREAM" class="java.io.InputStream" isForPrompting="false">
<defaultValueExpression>new ByteArrayInputStream($P{xmlString}.getBytes("UTF-8"))</defaultValueExpression>
</parameter>
Also when you run the report in Jaspersoft Studio make sure to select "Don't use a Data Adapter" in the Preview tab.
