Title Body

I'm working on a script which deals with an xml file. I'd like to update an attribute value in this xml file with xmlstarlet but it doesn't work. Here is a sample of the xml file: <?xml version="1.0" encoding="UTF-8"?> <channel name="xfce4-keyboard-shortcuts" version="1.0"> <property name="commands" type="empty"> <property name="default" type="empty"> <property name="&lt;Alt&gt;F2" type="empty"/> <property name="&lt;Control&gt;&lt;Alt&gt;Delete" type="empty"/> <property name="XF86Display" type="string" value="xrandr --output LVDS --auto --output VGA-0 --mode 1680x1050_60.00 --right-of LVDS"/> </property> <property name="custom" type="empty"> <property name="&lt;Alt&gt;F2" type="string" value="xfrun4"/> <property name="&lt;Control&gt;&lt;Alt&gt;Delete" type="string" value="xflock4"/> <property name="XF86Display" type="string" value="xrandr --output LVDS --auto --output VGA-0 --mode 1680x1050_60.00 --right-of LVDS"/> <property name="override" type="bool" value="true"/> </property> </property> </channel> And here is the command to update the property with the name "XF86Display" in the custom property node. xmlstarlet edit \ --update "/xml/channel[@name=xfce4-keyboard-shortcuts]/property[@name=commands]/property[@name=custom]/property[@name=XF86Display]/@value" \ --value "test" xfce4-keyboard-shortcuts.xml This output is strictly the same
