Question

我尝试根据给定xml的值对XML进行排序。在这个xml中，我需要根据education_details {DR，PDR，MSC，BSC}进行排序。我用过。请看下面的示例。

输入XML： -

    <?xml version="1.0" encoding="UTF-8"?>
     <Person>
       <document>
         <studentname>ACM</studentname>
         <educational_details>MSC</educational_details>
       </document>
       <document>
         <studentname>ACB</studentname>
         <educational_details>BSc</educational_details>
       </document>
       <document>
         <studentname>ACP</studentname>
         <educational_details>PDR</educational_details>
       </document>
       <document>
         <studentname>ACC</studentname>
         <educational_details>DR</educational_details>
       </document>
     </Person>

我尝试过如下所示。

XSL： -

 <xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:param name="pOrder" select="'DR,PDR,MSC,BSc'" />
        <xsl:template match="node()|@*">
            <xsl:copy>
                <xsl:apply-templates select="node()|@*">
                    <xsl:sort
                        select="string-length(
                                         substring-before(
                                            concat(',',$pOrder,','),
                                            concat(',',name(),',')))" />
                </xsl:apply-templates>
            </xsl:copy>
        </xsl:template>
    </xsl:stylesheet>

Out put

<?xml version="1.0" encoding="UTF-8"?>
     <Person>
       <document>
         <studentname>ACM</studentname>
         <educational_details>MSC</educational_details>
       </document>
       <document>
         <studentname>ACB</studentname>
         <educational_details>BSc</educational_details>
       </document>
       <document>
         <studentname>ACP</studentname>
         <educational_details>PDR</educational_details>
       </document>
       <document>
         <studentname>ACC</studentname>
         <educational_details>DR</educational_details>
       </document>
     </Person>

预期结果： -

<?xml version="1.0" encoding="UTF-8"?>
     <Person>
       <document>
         <studentname>ACC</studentname>
         <educational_details>DR</educational_details>
       </document>
       <document>
         <studentname>ACP</studentname>
         <educational_details>PDR</educational_details>
       </document>
       <document>
         <studentname>ACM</studentname>
         <educational_details>MSC</educational_details>
       </document>
       <document>
         <studentname>ACB</studentname>
         <educational_details>BSc</educational_details>
       </document>
     </Person>

我认为你想要类似的东西

<xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:param name="pOrder" select="'DR,PDR,MSC,BSc'" />

        <xsl:variable name="vSequence" select="tokenize($pOrder, ',')"/>

        <xsl:template match="node()|@*">
            <xsl:copy>
                <xsl:apply-templates select="node()|@*"/>
            </xsl:copy>
        </xsl:template>

        <xsl:template match="root">
            <xsl:copy>
                <xsl:apply-templates select="document">
                    <xsl:sort
                        select="index-of($vSequence, educational_details)" />
                </xsl:apply-templates>
            </xsl:copy>
        </xsl:template>

    </xsl:stylesheet>

改变

<?xml version="1.0" encoding="UTF-8"?>
<root>
       <document>
         <studentname>ACM</studentname>
         <educational_details>MSC</educational_details>
       </document>
       <document>
         <studentname>ACB</studentname>
         <educational_details>BSc</educational_details>
       </document>
       <document>
         <studentname>ACP</studentname>
         <educational_details>PDR</educational_details>
       </document>
       <document>
         <studentname>ACC</studentname>
         <educational_details>DR</educational_details>
       </document>
</root>

到

<?xml version="1.0" encoding="UTF-8"?><root><document>
         <studentname>ACC</studentname>
         <educational_details>DR</educational_details>
       </document><document>
         <studentname>ACP</studentname>
         <educational_details>PDR</educational_details>
       </document><document>
         <studentname>ACM</studentname>
         <educational_details>MSC</educational_details>
       </document><document>
         <studentname>ACB</studentname>
         <educational_details>BSc</educational_details>
       </document></root>

使用<xsl：sort> issue </xsl：sort>基于节点值对XML进行排序
