Update expresion in parseXml to find information

Iam using tesseract3.0,olena2.0 and i had a issue as follow:
At nuxeohome/tmp ocr_olena_xxx.xml was generated succesfuly but keywords 
where different so nuxeo-platform-ocr did not find anything untill i changed the code as below.
not text_region but TextRegion
not coords/point/@x but Coords/Point/@x 
not coords/point/@y but Coords/Point/@y
not image_regions but ImageRegion
A part of the xml generated : 
<TextRegion id="1" orientation="0" readingOrientation="0" readingDirection="left-to-right" type="text" reverseVideo="false" indented="false" textColour="indigo" kerning="2" color="#626351" colorReliability="0" baseline="95" meanline="72" xHeight="24" dHeight="-6" aHeight="32" charWidth="15">
      <Coords>
        <Point x="53" y="82"/>
       
        <Point x="53" y="83"/>
      </Coords>
        <Line text="5 arbiter | Trends" id="1" boldness="8.6875" boldnessReliability="73.0804" color="#626351" colorReliability="47.7542" orientation="0" readingOrientation="0" readingDirection="left-to-right" type="text" reverseVideo="false" indented="false" textColour="indigo" kerning="2" baseline="95" meanline="72" xHeight="24" dHeight="-6" aHeight="32" charWidth="15">
