xslt php ilk kardeşini ve onun tüm alt düğümleri seçmek

2 Cevap php

Nasıl bir tüm alt düğümler ile bir xml düğüm ilk kardeş seçin ve üzerine bazı dönüşümler geçerlidir? Şimdiye kadar sadece ilk ve tek kardeş ilk kardeşini (hiçbir alt düğümler) veya xml düğüm şu şeyi ya seçilmiş başardı.

Bunun gibi xhtmli var ki:

<div class="chapter">Chapter <span class="number">1.1</span> Lorum ipsum</div>
<h2 class="article">Article <span class="number">1.</span> Lorum ipsum</h2>
<p>Lorum ipsum</p>

Ve biz peşinde sonuç böyle xml olur:

<chapter>
  <heading>
    <label>Chapter</chapter>
    <number>1.1</number>
    <title>Lorum ipsum</title>
  </heading>
  <article>
    <heading>
      <label>Article</chapter>
      <number>1.</number>
      <title>Lorum ipsum</title>
    </heading>
    <par>Lorum ipsum</par>
  </article>
</chapter>

Benim tahminim ben etiket ve başlık etiketleri sağ olsun bazı regex büyü yapmak için ihtiyaç olduğunu, ancak bu aynı zamanda düz xslt kullanarak yapılmış olabilir, bu harika olurdu.
