XSLT 字符串 Wrap:How 我是否在换行符 (\n) 的字符串中换行

Question

我们想为给定的 XML 编写 XSLT 转换。我们正在尝试在按下 ENTER KEY 时在换行符处为注释元素换行。其中，<Comment> 个元素在应用 XSLT 转换后拆分为 6 个不同的行项目。

注：这里的“\n”是换行符。意思是结束当前行，换行。

我们尝试了以下方法：

其中观察到的模式：
<StockCode> 元素为空白，因为每个行项目都有评论子字符串。而 StockCode 元素对所有这些元素都有价值 <comment> 元素为空
<OrderDetail> 这里是重复节点。

输入XML:

<?xml version="1.0" encoding="WINDOWS-1252"?>

-<SalesOrders xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD" xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance">

以上代码分为 6 个不同的行项目（即针对每个 OrderLineID），因此，我们试图在评论字段上实现子字符串。

如何为换行符处的注释子串编写XSLT转换文件？

提前致谢！

为了将问题最小化为此处的主要问题，请考虑以下样式表：

XSLT 2.0

<xsl:stylesheet version="2.0" 
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="*"/>

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

<xsl:template match="OrderDetails">
    <xsl:copy>
        <xsl:variable name="stockcode" select="StockLine/StockCode" />
        <xsl:for-each select="tokenize(StockLine/Comment, '\n')">
            <StockLine>
                <xsl:copy-of select="$stockcode"/>
                <Comment>
                    <xsl:value-of select="normalize-space(.)"/>
                </Comment>
                <OrderLineID>???</OrderLineID>
            </StockLine>
        </xsl:for-each>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

应用于以下输入：

XML

<SalesOrders xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">
  <Orders>
    <OrderHeader>
      <Customer>000016</Customer>
      <OrderDate>2016-04-19</OrderDate>
      <SalesForceOrderNumber>ORD-411324</SalesForceOrderNumber>
    </OrderHeader>
    <OrderDetails>
      <StockLine>
        <StockCode>NIL</StockCode>
        <Comment>EDIORDER-SAVE COMMENTS\n C3 Generic\n LOC 0833\n Expected arrival 01/07/2016\n  OTYPE NE\n TRKPC 01 GM/00007643020008361321</Comment>
      </StockLine>
    </OrderDetails>
  </Orders>
</SalesOrders>

结果将是：

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

      <OrderHeader>
         <Customer>000016</Customer>
         <OrderDate>2016-04-19</OrderDate>
         <SalesForceOrderNumber>ORD-411324</SalesForceOrderNumber>
      </OrderHeader>
      <OrderDetails>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>EDIORDER-SAVE COMMENTS</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>C3 Generic</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>LOC 0833</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>Expected arrival 01/07/2016</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>OTYPE NE</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
         <StockLine>
            <StockCode>NIL</StockCode>
            <Comment>TRKPC 01 GM/00007643020008361321</Comment>
            <OrderLineID>???</OrderLineID>
         </StockLine>
      </OrderDetails>
   </Orders>
</SalesOrders>

我不知道 OrderLineID 的内容应该来自哪里。

重要提示：

如果输入 Comment 包含实际换行符 - IOW，如果您的实际输入是：

XML

<SalesOrders xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance" xsd:noNamespaceSchemaLocation="SORTOIDOC.XSD">
  <Orders>
    <OrderHeader>
      <Customer>000016</Customer>
      <OrderDate>2016-04-19</OrderDate>
      <SalesForceOrderNumber>ORD-411324</SalesForceOrderNumber>
    </OrderHeader>
    <OrderDetails>
      <StockLine>
        <StockCode>NIL</StockCode>
        <Comment>EDIORDER-SAVE COMMENTS
C3 Generic
LOC 0833
Expected arrival 01/07/2016
 OTYPE NE
TRKPC 01 GM/00007643020008361321</Comment>
      </StockLine>
    </OrderDetails>
  </Orders>
</SalesOrders>

然后使用：

<xsl:for-each select="tokenize(StockLine/Comment, '\n')">
