ORA-31011: XML parsing failed while trying to get XML output

When trying to get a value from an CLOB XML column, I get the following error:

ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00601: Invalid token in: '/l-analysis/vehicle/odometer-reading/reading value/text()'
31011. 00000 -  "XML parsing failed"
*Cause:    XML parser returned an error while trying to parse the document.
*Action:   Check if the document to be parsed is valid.

I have the following XML output:

<?xml version="1.0" encoding="UTF-8"?>
<l-analysis>
   <vehicle>
      <make>SAAB</make>
      <model>9000 CSI</model>
      <body-style code="SL">Saloon</body-style>
      <vehicle-type code="7">Passenger car/van</vehicle-type>
      <odometer-reading latest="true">
         <reading value="154267213">154267213</reading>
         <reading-date value="2006-07-17">17-Jul-2006</reading-date>
      </odometer-reading>
   </vehicle>
</l-analysis>

When trying to get the reading value value, I am running this query:

select XMLTYPE(xml_data).EXTRACT('/l-analysis/vehicle/odometer-reading/reading value/text()').getStringVal() AS XML FROM lm

I believe the error is due reading value having spaces? 'Cause for another XML column that doesn't have spaces it works.

How could I get this working?
