这是我的XSL
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0"
encoding="iso-8859-1" indent="yes"/>
<xsl:template match="/">
<countries>
<xsl:for-each select=".//country">
<xsl:sort select="@population" order="descending" data-type="number"/>
<country>
<name>
<xsl:value-of select="@name"/>
</name>
<population>
<xsl:value-of select="@population"/>
</population>
<area>
<xsl:value-of select="@area"/>

<xsl:value-of select="@city"/>
</city>
</xsl:for-each>
</cities>
</country>
</xsl:for-each>
</countries>
</xsl:template>
</xsl:stylesheet>
在XSL之上，无法在输出xml中获得city名称。我认为我为城市做错了each-select。
第二，如果任何国家的城市不止一个，如何按人口从高到低的顺序排序？
我可以知道吗，这是怎么回事。我是XSLT的新手
答案 0 :(得分：0)
验证码：-
<cities>
<xsl:for-each select="city">
<city>
<xsl:value-of select="name"/>
</city>
</xsl:for-each>
</cities>
答案 1 :(得分：0)
因为您已经位于.//country下，所以无需在第二个for-each下再次指定.// country。
<cities>
<xsl:for-each select="city">
<city>
<xsl:value-of select="name"/>
</city>
</xsl:for-each>
</cities>
答案 2 :(得分：0)
1）。如上所述，@ Ansari建议您已经在country node()上，因此不需要内部for-each部分.//country，因为它正在当前上下文中搜索country这就是为什么您的输出中没有任何关于城市的条目的原因。
2）。您可以像上次在国家/地区中那样在内部循环中使用xsl:sort，请参考下面的代码，希望它可以让您知道在哪里出错：
<?xml version="1.0" encoding="UTF-8"?>

<xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"/>
<xsl:template match="/">
<countries>
<xsl:for-each select="//country">
<xsl:sort select="@population" order="descending" data-type="number"/>
<country>
<name>
<xsl:value-of select="@name"/>
