Regression: Cannot query all nodes using indices

[srebhan]

When using a query such as //phones[1]/number it is expected to return the first element of each finding of the phones node in subtrees (see xpath playground).

With the following code

package main

import (
	"fmt"
	"strings"

	"github.com/antchfx/xmlquery"
)

const xml string = `
<?xml version="1.0"?>
<root>
    <people>
        <age>42</age>
        <email>[email protected]</email>
        <id>101</id>
        <name>John Doe</name>
    </people>
    <people>
        <age>40</age>
        <id>102</id>
        <name>Jane Doe</name>
    </people>
    <people>
        <age>12</age>
        <email>[email protected]</email>
        <id>201</id>
        <name>Jack Doe</name>
        <phones>
            <number>555-555-5555</number>
            <type>2</type>
        </phones>
    </people>
    <people>
        <age>19</age>
        <email>[email protected]</email>
        <id>301</id>
        <name>Jack Buck</name>
        <phones>
            <number>555-555-0000</number>
            <type>1</type>
        </phones>
        <phones>
            <number>555-555-0001</number>
        </phones>
        <phones>
            <number>555-555-0002</number>
            <type>2</type>
        </phones>
    </people>
    <people>
        <age>16</age>
        <email>[email protected]</email>
        <id>1001</id>
        <name>Janet Doe</name>
        <phones>
            <number>555-777-0000</number>
        </phones>
        <phones>
            <number>555-777-0001</number>
            <type>1</type>
        </phones>
    </people>
    <tags>home</tags>
    <tags>private</tags>
    <tags>friends</tags>
</root>
`

func main() {
	doc, err := xmlquery.Parse(strings.NewReader(xml))
	if err != nil {
		panic(err)
	}

	nodes, err := xmlquery.QueryAll(doc, "//phones[1]/number")
	if err != nil {
		panic(err)
	}

	for i, n := range nodes {
		fmt.Printf("node %d: %s=%v\n", i, n.Data, n.InnerText())
	}
}

we see

node 0: number=555-555-5555
node 1: number=555-555-0000
node 2: number=555-777-0000

up to version v1.2.5 of this package. However, commit ed2f6ee changes the behavior and now the code only produces

node 0: number=555-555-5555

Thanks @zhengchun! I can confirm that this solves the issue.
