Alberto, rather than filtering the output, you could also include a predicate in the XPath to select only the CoverageId elements you want:
$ curl -s 'http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCapabilities' | xpath -q -e '//wcs:CoverageId/text()[contains(.,"Sample")]' nurc__Arc_Sample nurc__Img_Sample This example is not strictly what you want if you only want to match a substring at the end of the CoverageId text. xpath appears to support only XPath 1.0 so does not support ends-with() (from XPath 2.0), but you can make your own with this ugly but effective construct: $ curl -s 'http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCapabilities' | xpath -q -e '//wcs:CoverageId/text()[substring(.,string-length(.)-string-length("Sample")+1)="Sample"]' nurc__Arc_Sample nurc__Img_Sample In your case this would be: curl -s 'http://localhost:8080/geoserver/wcs?service=WCS&version=2.0.1&request=GetCapabilities' | xpath -q -e '//wcs:CoverageId/text()[substring(.,string-length(.)-string-length("RGB")+1)="RGB"]' Kind regards, Ben.
