node should select only 1 sibling

[rightjoin]

Hi,

Please look at the following test case. When I select follow-sibling::child[1], then only the first child should be selected.

`func TestFetchSibling(t *testing.T) {

xml := `<?xml version="1.0" encoding="UTF-8"?>
<node>
	<element index="one"/>
	<hash attr="one"/>
	<element index="two"/>
	<hash attr="two"/>
</node>
`

doc, _ := xmlquery.Parse(strings.NewReader(xml))
ele1 := xmlquery.FindOne(doc, "//node/element")

// specify xpath to pick the first element only
hashes := xmlquery.Find(ele1, "following-sibling::hash[1]")
if len(hashes) != 1 {
	t.Errorf("lenght should be 1, but found %d", len(hashes))
}

}
`
