XSLT:How 维护 XML 中标签的顺序

Question

我们有输入 XML.In，我们无法维护标签的顺序。基本上，我们在 XSLT.Then 中写了转换，它也损害了 2 Looping 标签的顺序。

我们想使用 <UserDefined> 标签维护顺序。

输入XML:

  <?xml version="1.0" encoding="UTF-8"?>
<SalesOrders xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">

我们在上面尝试了 XSLT。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
   <xsl:output method="xml" encoding="Windows-1252" indent="yes" />
   <xsl:template match="@* | node()">
      <xsl:copy>
         <xsl:apply-templates select="@* | node()" />
      </xsl:copy>
   </xsl:template>
   <xsl:template match="StockLine[not(StockCodeDescription) and not (OrderQty) and not(Price)]">
      <CommentLine>
         <Comment>
            <xsl:value-of select="StockCode" />
         </Comment>
         <xsl:copy-of select="OrderLineID" />
         <xsl:copy-of select="UserDefined" />
      </CommentLine>
   </xsl:template>
   <xsl:template match="CommentLine">
      <CommentLine>
         <xsl:for-each-group select="CommentLine" group-by="CommentLine">
            <xsl:apply-templates select="current-group()" />
         </xsl:for-each-group>
      </CommentLine>
   </xsl:template>
   <xsl:template match="CommentLine[OrderLineID = preceding-sibling::StockLine/OrderLineID and not(Comment)]" />
   <xsl:template match="CommentLine[some $sib in preceding-sibling::CommentLine satisfies deep-equal(., $sib)]" />
</xsl:stylesheet>

Answer 1

如果您只想按 UserDefined 元素值对 OrderDetails 元素的子元素进行排序，则

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"
  xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

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

    <xsl:template match="OrderDetails">
        <xsl:copy>
            <xsl:apply-templates select="*">
                <xsl:sort select="xs:integer(UserDefined)"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>
</xsl:transform>

就足够了（在线 http://xsltransform.net/jyRYYjt）。但是，我不确定为什么要包括所有那些看起来无关的其他模板。
