I want to use clip-path to implement effect like: svg with text clip-path,  but open in browser it just display an empty
svg.  I wrap the path with <g> tag, then it failed.
<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32" viewBox="0 0 32 32" fill="none" style="
    width: 200px;
    height:  200px;
">
    <defs>
        <clipPath id="text-path">
            <g clip-rule="evenodd" fill-rule="evenodd">
                <path d="M0 0H14V2H2V13H22V10H24V13H32V27H24V32H0V0ZM2 30V27H22V30H2Z"/>
                <path d="M16 0L24 8H16V0Z"/>
                <text x="7.5" y="23">PDF</text>
            </g>
        </clipPath>
    </defs>
    <g clip-path="url(#text-path)" fill="red">
        <path d="M0 0H14V2H2V13H22V10H24V13H32V27H24V32H0V0ZM2 30V27H22V30H2Z"/>
        <path d="M16 0L24 8H16V0Z"/>
    </g>

    <style>
        text {dominant-baseline: hanging;font-size: 8px;font-weight: bold;}
    </style>
</svg>

it should be displayed in browser.

How can I use clip-path to achieve a text effect on my SVG in the browser?
In your example (above) you may remove the wrapping group around the 2 paths and the text and it would work.
 <clipPath id="text-path">
        <!-- <g clip-rule="evenodd" fill-rule="evenodd"> -->
            <path d="M0 0H14V2H2V13H22V10H24V13H32V27H24V32H0V0ZM2 30V27H22V30H2Z"/>
            <path d="M16 0L24 8H16V0Z"/>
            <text x="7.5" y="23">PDF</text>
        <!-- </g> -->
 </clipPath>

However you won't see the text.
If what you need is to see the text as a hole in the shapes you will need a mask where the text is black and the 2 paths are white. In the case of the mask  you can use a group if you think you need it.


<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32" viewBox="0 0 32 32" style="
    width: 200px;
    height:  200px;
    background:silver">
  <mask id="m">
  <g fill="white">
    <path d="M0 0H14V2H2V13H22V10H24V13H32V27H24V32H0V0ZM2 30V27H22V30H2Z" />
    <path d="M16 0L24 8H16V0Z" />
  </g>
    <text x="7.5" y="23" fill="black">PDF</text>
  </mask>

  <rect width="32" height="32" mask="url(#m)" fill="red" />

  <style>
    text {
      dominant-baseline: hanging;
      font-size: 8px;
      font-weight: bold;
    }
  </style>

</svg>
