I am having trouble getting an XPath function to work. I am supposed to pull only the entries in the XML file that the name of them ends with the letter 'z' and I cannot get it to work. I am xmllint to manipulate the file with the cat command.
ends-with() only works on XPath 2.0 and I'm pretty sure the server only has XPath 1.0 so I have tried entering this command:
cat //country/city[substring(@name, string-length(@name) - string-length('z') +1)]/name
but I keep getting an error, and I am not sure if I am writing it improperly or if it is not the correct way to do it.
Your XPath is missing the step of checking return value of substring() whether or not it is equals to the expected string ending value "z". So the correct XPath would be :
//country[substring(@name, string-length(@name) - string-length('z') +1) = 'z']/@name
And since -string-length('z') +1 equals to 0, that part can be omitted to get a simpler XPath, similar to the one posted by @Kirill Polishchuk in the other answer.
