让我们把这个列表放在你的XSLT文件之外。比方说 "order.xml"。XSLT代码应该读取这个XML，并按照这个顺序组织书籍。我们应该能够改变这个顺序，如果我们重新运行XSLT代码，输出应该是预期的，如果我改变了顺序的流派在order.xml文件，在该顺序输出将是。

订单.xml

    <?xml version="1.0" encoding="UTF-8"?>
<order>

    <genre>Fantasy</genre>
    <genre>Science Fiction</genre>
    <genre>Romance</genre>
    <genre>Computer</genre>
    <genre>Horror</genre>
</order>

plz help me sortout this problem

当流派已经按照你想要的顺序排序时，就没有必要再进行任何排序。只需按照给定的顺序列出流派，然后是每个流派的书籍列表。

下面是一个最小化的例子。

XSLT 1. 0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:param name="input-xml" select="/"/>
<xsl:param name="genres" select="document('order.xml')"/>

<xsl:key name="book-by-genre" match="book" use="genre" />

<xsl:template match="/catalog">
    <html>
        <body>
            <h1>MY LIBRARY</h1>
            <xsl:for-each select="$genres/order/genre">
                <xsl:variable name="genre" select="." />
                <!-- switch context back to input XML -->
                <xsl:for-each select="$input-xml">
                    <xsl:variable name="books-in-genre" select="key('book-by-genre', $genre)" />
                    <xsl:if test="$books-in-genre">
                         <h2>
                            <xsl:value-of select="$genre"/>
                         </h2>
                         <xsl:for-each select="$books-in-genre">
                             <p>
                                <xsl:value-of select="title"/>
                             </p>
                         </xsl:for-each>     
                    </xsl:if>
                </xsl:for-each>
            </xsl:for-each>
        </body>
    </html>
</xsl:template>

</xsl:stylesheet>

结果

<html>
<body>
<h1>MY LIBRARY</h1>
<h2>Fantasy</h2>
<p>Midnight Rain</p>
<p>Maeve Ascendant</p>
<p>Oberon's Legacy</p>
<p>The Sundered Grail</p>
<h2>Science Fiction</h2>
<p>Paradox Lost</p>
<h2>Romance</h2>
<p>Lover Birds</p>
<p>Splish Splash</p>
<h2>Computer</h2>
<p>XML Developer's Guide</p>
<p>Microsoft .NET: The Programming Bible</p>
<p>MSXML3: A Comprehensive Guide</p>
<h2>Horror</h2>
<p>Creepy Crawlies</p>
</body>
</html>

A @michaelhor257k指出，你可以将其作为连接而不是排序来实现。但也可以使用 xsl:sort，至少在XSLT 2.0以上的版本中。<xsl:sort select="index-of($genres, genre)"/> 其中$genres是作为字符串序列的流派列表。

当你向本网站（或任何地方）提交XSLT问题时，请说明你是否对你正在使用的语言版本有任何限制。在以后的语言版本中，很多事情都会变得简单很多，但遗憾的是，很多用户还在使用原来的1.0版本。
