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时在换行符处对注释元素进行文本换行。其中，<Comment>元素在应用XSLT转换后拆分了6个不同的订单项。

注意： 这里“\ n”是换行符。这意味着结束当前行并转到新行。

我们尝试了以下内容：

在其中观察到的模式：
对于在每个订单项中都有评论子字符串的所有人，<StockCode>元素为空。而StockCode元素对所有<comment>元素的值都是空白的 <OrderDetail>在这里重复节点。

输入XML：

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

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

XSLT转换后的预期XML：

上面的代码分为6个不同的行项目（即每个OrderLineID）。在那里，我们试图在注释字段上实现子串。

如何在新行字符处为Comment Substring编写XSLT转换文件？

提前致谢！

要将问题最小化到此处的主要问题，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：

<强> 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">
   <Orders>
      <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：

如果输入Comment包含实际的换行符 - IOW，如果您的实际输入是：

<强> 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')">

加了：

给出以下输入：

<强> 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>ABB-CDE-FGH-01</StockCode> <OrderDescription>EDIORDER-SAVE COMMENTS C3 Generic LOC 0833 Expected arrival 01/07/2016 OTYPE NE TRKPC 01 GM/00007643020008361321</OrderDescription> <OrderLineID>OR-1561179</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <OrderLineID>OR-1561180</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <OrderLineID>OR-1561181</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <OrderLineID>OR-1561182</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <OrderLineID>OR-1561183</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <OrderLineID>OR-1561184</OrderLineID> </StockLine> </OrderDetails> </Orders> </SalesOrders>

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="*"/>  <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="StockLine"> <xsl:variable name="i" select="position()" /> <xsl:copy> <xsl:copy-of select="StockCode"/> <Comment> <xsl:value-of select="normalize-space(tokenize(../StockLine[1]/OrderDescription, '\n')[$i])"/> </Comment> <xsl:copy-of select="OrderLineID"/> </xsl:copy> </xsl:template> </xsl:stylesheet>

将返回：

<强>结果

<?xml version="1.0" encoding="UTF-8"?> <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>ABB-CDE-FGH-01</StockCode> <Comment>EDIORDER-SAVE COMMENTS</Comment> <OrderLineID>OR-1561179</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <Comment>C3 Generic</Comment> <OrderLineID>OR-1561180</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <Comment>LOC 0833</Comment> <OrderLineID>OR-1561181</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <Comment>Expected arrival 01/07/2016</Comment> <OrderLineID>OR-1561182</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <Comment>OTYPE NE</Comment> <OrderLineID>OR-1561183</OrderLineID> </StockLine> <StockLine> <StockCode>Nil</StockCode> <Comment>TRKPC 01 GM/00007643020008361321</Comment> <OrderLineID>OR-1561184</OrderLineID> </StockLine> </OrderDetails> </Orders> </SalesOrders>
