How xpath read xml spaced elements?

Question

This is the xml, unfortunately anything of the XML is NOT CHANGEABLE :

<allowance name ='' /> <allowance type ='' /> <allowance value='' />

And i need to obtain only "allowance value" with xpath in java. How can it be done?

Answer 1

This expression will return all 'allowance' elements that have the 'value' attribute:

//allowance[@value]

This will return just the value of "value":

//allowance[@value]/@value

Answer 2

您可以尝试：/ root // allowance [@value]
