last() not working on subgroups #76
Description
Hello,
first of all, thanks for your amazing work, it's really useful to me.
I'm having an issue when using the last() function on a subgroup, for example on a result of another filter.
For example, this piece of code:
package main
import (
"fmt"
"github.com/antchfx/xmlquery"
"strings"
)
func main() {
xml := `
<root>
<test foo="bar">First</test>
<test foo="bar">Second</test>
<test foo="xyz">Third</test>
</root>
`
doc, err := xmlquery.Parse(strings.NewReader(xml))
if err != nil {
panic(err)
}
tests, err := xmlquery.QueryAll(doc, `(//test[@foo="bar"])[last()]`)
if err != nil {
panic(err)
}
for _, test := range tests {
fmt.Println(test.InnerText())
}
}I would expect this to print "Second", but it prints nothing, because the output from the query has no elements.
Am I doing something wrong, or is this an issue on the last() function?
Thank you!
