如何使用xsl按属性值对xml文件夹和文件进行排序?

首先,对于xsl,我是noob。 我有一个不正确的.xml文档。

xml示例:

<folder-one order="2">
    <another-folder order="2">
        <some-file order="2">title</some-file>
        <some-file order="1">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
    <another-folder order="1">
        <some-file order="2">title</some-file>
        <some-file order="1">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
</folder-one>

<folder-two order="1">
    <another-folder order="2">
        <some-file order="2">title</some-file>
        <some-file order="1">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
    <another-folder order="1">
        <some-file order="2">title</some-file>
        <some-file order="1">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
</folder-two>

我需要这个:

<folder-one order="1">
    <another-folder order="1">
        <some-file order="1">title</some-file>
        <some-file order="2">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
    <another-folder order="2">
        <some-file order="1">title</some-file>
        <some-file order="2">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
</folder-one>

<folder-two order="2">
    <another-folder order="1">
        <some-file order="1">title</some-file>
        <some-file order="2">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
    <another-folder order="2">
        <some-file order="1">title</some-file>
        <some-file order="2">title</some-file>
        <some-file order="3">title</some-file>
    </another-folder>
</folder-two>

无论我尝试做什么,我都搞砸了,甚至无法显示结构。 我尝试过使用xsl:for-each和xsl:sort但它没有帮助。可能是因为我做得不对。我不知道还能做什么......

这是已经存在的xsl。无论如何改变它会给我带来麻烦..

<xsl:stylesheet  version="1.0" 
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform"
xmlns:ectd = "http://www.ich.org/ectd"  
xmlns:xlink = "http://www.w3c.org/1999/xlink">
<xsl:template match="/">
    <html>
        <head>
            <link rel="stylesheet" href="util/style/screen.css" type="text/css" media="screen"/>
        </head>
        <body>
            <h2>eCTD <font size="-1"> DTD version <xsl:value-of select="/ectd:ectd/@dtd-version"/></font></h2>
            <xsl:apply-templates select="/ectd:ectd/*"/>
        </body>
    </html>
</xsl:template>

<xsl:template match="*">
    <ul type="square">
        <li>
            <xsl:value-of select="name()"/>
            <font color="green">
                <xsl:if test="@manufacturer != ''"> [manufacturer: <xsl:value-of select="@manufacturer"/>] </xsl:if>
                <xsl:if test="@substance != ''"> [substance: <xsl:value-of select="@substance"/>] </xsl:if>
                <xsl:if test="@product-name != ''"> [product name: <xsl:value-of select="@product-name"/>] </xsl:if>
                <xsl:if test="@dosageform != ''"> [dosage form: <xsl:value-of select="@dosageform"/>] </xsl:if>
                <xsl:if test="@indication != ''"> [indication: <xsl:value-of select="@indication"/>] </xsl:if>
                <xsl:if test="@excipient != ''"> [excipient: <xsl:value-of select="@excipient"/>] </xsl:if>
            </font>
        </li>
        <xsl:apply-templates/>
    </ul>
</xsl:template>

<xsl:template match="leaf">
    <ul type="square">
        <li>
            <xsl:element name="a">
                <xsl:attribute name="href"><xsl:value-of select="@xlink:href"/></xsl:attribute>
                <xsl:value-of select="title"/>
            </xsl:element>
            <font color="red">
                [<xsl:value-of select="@operation"/>]
            </font>
        </li>
    </ul>
</xsl:template>

<xsl:template match="node-extension">
    <ul type="square">
        <li>
            <xsl:value-of select="title"/>
            <xsl:apply-templates select="leaf|node-extension"/>
        </li>
    </ul>   
</xsl:template>

“leaf”在我的例子中是“some-file”....

您只需要向着名的identity transform template添加xsl:sort指令:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()">
        <xsl:sort select="@order" data-type="number" order="ascending"/>
    </xsl:apply-templates>
  </xsl:copy>
</xsl:template>
</xsl:stylesheet>

请注意,您的XML示例是格式正确的文档:您缺少根元素。
