 Fixed I think in the xpath.c patch I just posted,

~/XML -> cat tst.xml
<doc><value>something</value></doc>
~/XML -> ./testXPath -i tst.xml 'concat(string(/doc/value/text()),"hello")'
Object is a string : somethinghello
~/XML -> ./testXPath -i tst.xml 'concat("hello",string(/doc/value/text()))'
Object is a string : hellosomething
~/XML ->

  looks better :-)
