Qweb Xpath of child node in odoo / openERP?

问题

Here i want insert a LI item inside existing UL

I tried this,

XML

<ul id="top_menu">
    <li><a>1</a></li>
    <li><a>2</a></li>
    <li><a>3</a></li>
</ul>

XPATH

  <xpath expr="//ul[@id='top_menu']/li[1]" position="after">
     <li><a>100</a></li>
  </xpath>

I got my new item "100" at last item of <ul>. but i need it in after 1st item. Thanks in advance.

Sometime in tricky solution, we need to override/replace base id and than rearrange it based on our requirement.

try with this code:

Replace your code

<xpath expr="//ul[@id='top_menu']/li[1]" position="after">
    <li><a>100</a></li>
</xpath>

with

<xpath expr="//ul[@id='top_menu']" position="replace">
    <ul id="top_menu">
        <li><a>1</a></li>
        <li><a>100</a></li>
        <li><a>2</a></li>
        <li><a>3</a></li>
    </ul>
</xpath>
