XML和XSL沒有得到期望的結果

Question

我有一個食譜的XML文件。每個配方都使用一個元素定義，My XSL我想用<xsl:for-each select="//recipe">填充一個表格。唯一的問題是我沒有得到理想的結果。除了for-each之外的所有東西都可以正常工作，並且可以顯示，但for-each中的所有內容都沒有出現。

我沒有看到我的XSL中有任何錯誤，但後來我不是最好的創建它們。任何幫助，將不勝感激。

Answer 1

這是因爲在XML的默認命名空間xmlns="http://www.w3schools.com"的。

您可以：

1. 從XML刪除它。

2. 使用前綴添加名稱空間，並在select中使用前綴。 （select="//x:recipe"）

3. 如果您使用的是XSLT 2.0，請使用*作爲select中的前綴。 （select="//*:recipe"）

4. 在select中使用local-name()。 （select="//*[local-name() = 'recipe']"）

Answer 2

順便說一句，這img元素可以使用

<img src="{image}" alt="recipe"/>
