Question

抱歉我的英语不好。我正在w3schools.com上学习XML和XSLT。页面https://www.w3schools.com/XML/xsl_choose.asp包含＆＃34;自己动手＆＃34;元件。

我在以下后更新了XSLT代码：

<xsl:for-each select="catalog/cd">

我补充说：

<xsl:sort select="price"/>

它有效，但结果的第一个元素是字母（价格），而不是第二个。屏幕：

Answer 1

解决方案1 

更改输入元素

    <COMPANY>Stax Records</COMPANY>
    <PRICE>7.90</PRICE>
    <YEAR>1968</YEAR>

到

    <company>Stax Records</company>
    <price>7.90</price>
    <year>1968</year>

解决方案2

或只是更改代码

<xsl:sort select="price"/>

到

<xsl:sort select="price|PRICE"/>

这个xsl：sort有什么问题？
