xsl用于使用分组和键在一个xml内的多个xml行

标签： xml xslt key grouping

有人可以协助创建密钥，以便使用xsl正确分组xml文件吗？使用收到的xml我需要能够将数据带入我的ERP系统，从而为每个新供应商以及每个目的地仓库创建新的采购订单。换句话说，从下面我需要为LIY0001创建的采购订单并转到A4（这必须包括与供应商和仓库相关的所有行）。类似地，需要为WOR0001转到A4而另一个为WOR0001转到A5创建新的采购订单（同样，所有与两个键相关的行都进入必要的采购订单分组）。对于下面的示例，应该创建3个单独的采购订单。

以下是xml的示例：

<rows>
<row>
<SUPPLIER>LIY0001</SUPPLIER>
<DESTWHS>A4</DESTWHS>
<RELEASE_DATE>2013-02-14</RELEASE_DATE>
<DUE_DATE>2013-05-13</DUE_DATE>
<ITEM>5021616</ITEM>
<QTY>528</QTY>
<LINE_ITEM_NO>1</LINE_ITEM_NO>
<CUST_PO_NO>LIY0001-2013-02-14</CUST_PO_NO>
<PURCHASEPRICE>5.25</PURCHASEPRICE>
</row>
<row>
<SUPPLIER>LIY0001</SUPPLIER>
<DESTWHS>A4</DESTWHS>
<RELEASE_DATE>2013-02-14</RELEASE_DATE>
<DUE_DATE>2013-05-13</DUE_DATE>
<ITEM>5021816</ITEM>
<QTY>222</QTY>
<LINE_ITEM_NO>2</LINE_ITEM_NO>
<CUST_PO_NO>LIY0001-2013-02-14</CUST_PO_NO>
<PURCHASEPRICE>5.90</PURCHASEPRICE>
</row>
<row>
<SUPPLIER>WOR0001</SUPPLIER>
<DESTWHS>A4</DESTWHS>
<RELEASE_DATE>2013-02-14</RELEASE_DATE>
<DUE_DATE>2013-05-13</DUE_DATE>
<ITEM>650616</ITEM>
<QTY>129</QTY>
<LINE_ITEM_NO>9</LINE_ITEM_NO>
<CUST_PO_NO>WOR0001-2013-02-14</CUST_PO_NO>
<PURCHASEPRICE>4.46</PURCHASEPRICE>
</row>
<row>
<row>
<SUPPLIER>WOR0001</SUPPLIER>
<DESTWHS>A5</DESTWHS>
<RELEASE_DATE>2013-02-14</RELEASE_DATE>
<DUE_DATE>2013-05-13</DUE_DATE>
<ITEM>650610</ITEM>
<QTY>129</QTY>
<LINE_ITEM_NO>1</LINE_ITEM_NO>
<CUST_PO_NO>WOR0001-2013-02-14</CUST_PO_NO>
<PURCHASEPRICE>3.5</PURCHASEPRICE>
</row>
<row>
</rows>

这是我创建的翻译文件：

<?xml version="1.0" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" encoding="Windows-1252" omit-xml-declaration="yes" />
<xsl:template match="/">
<PostPurchaseOrders>
    <Orders>
      <OrderHeader> 
      <xsl:for-each select = "rows/row">
      <CustomerPoNumber><xsl:value-of select="CUST_PO_NO"/></CustomerPoNumber> 
      <Supplier><xsl:value-of select="SUPPLIER"/></Supplier>
          <OrderDate><xsl:value-of select="RELEASE_DATE"/></OrderDate>
          <DueDate><xsl:value-of select="DUE_DATE"/></DueDate>
         <Warehouse><xsl:value-of select="DESTWHS"/></Warehouse>
     </xsl:for-each>
     </OrderHeader> 
      <OrderDetails>
     <xsl:for-each select = "rows/row">
       <StockLine>
         <PurchaseOrderLine><xsl:value-of select="LINE_ITEM_NO"/></PurchaseOrderLine>
            <StockCode><xsl:value-of select="ITEM"/></StockCode>
            <Warehouse><xsl:value-of select="DESTWHS"/></Warehouse>
           <OrderQty><xsl:value-of select="QTY"/></OrderQty>
           <Price><xsl:value-of select="PURCHASEPRICE"/></Price>
          </StockLine>
         </xsl:for-each>
       </OrderDetails>       
       </Orders>
<PostPurchaseOrders>
</xsl:template>
</xsl:stylesheet>

以下是我需要将xml转换为ERP系统的内容：

<PostPurchaseOrder>
<Orders>
    <OrderHeader>
        <Supplier>LIY0001</Supplier>
        <CustomerPoNumber>example po</CustomerPoNumber>
        <OrderDate>2013-02-03</OrderDate>
        <Warehouse>A1</Warehouse>
    </OrderHeader>
    <OrderDetails>
        <StockLine>
            <PurchaseOrderLine>1</PurchaseOrderLine>
            <StockCode>12022</StockCode>
            <OrderQty>10</OrderQty>
        </StockLine>
        <StockLine>
            <PurchaseOrderLine>2</PurchaseOrderLine>
            <StockCode>15014</StockCode>
            <OrderQty>15</OrderQty>
        </StockLine>
    </OrderDetails>
</Orders>
</PostPurchaseOrders>

如何帮助我将我的翻译文件更改为2个密钥的分组，以便为​​每个供应商以及每个目的地仓库将许多行汇入一个采购订单，我们将不胜感激。

您的XSLT和示例输出之间存在一些不一致，因此我将模拟示例输出。这应该实现您正在寻找的分组：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:key name="kOrder" match="row" use="concat(SUPPLIER, '+', DESTWHS)"/>

  <xsl:template match="/*">
    <PostPurchaseOrder>
      <xsl:apply-templates
        select="row[generate-id() = 
                    generate-id(key('kOrder', concat(SUPPLIER, '+', DESTWHS))[1])]"
        mode="group"/>
    </PostPurchaseOrder>
  </xsl:template>

  <xsl:template match="row" mode="group">
    <OrderHeader>
      <Supplier>
        <xsl:value-of select="SUPPLIER" />
      </Supplier>
      <CustomerPoNumber>
        <xsl:value-of select="CUST_PO_NO" />
      </CustomerPoNumber>
      <OrderDate>
        <xsl:value-of select="RELEASE_DATE" />
      </OrderDate>
      <Warehouse>
        <xsl:value-of select="DESTWHS" />
      </Warehouse>
    </OrderHeader>
    <OrderDetails>
      <xsl:apply-templates select="key('kOrder', concat(SUPPLIER, '+', DESTWHS))" />
    </OrderDetails>
  </xsl:template>

  <xsl:template match="row">
    <StockLine>
      <PurchaseOrderLine>
        <xsl:value-of select="LINE_ITEM_NO" />
      </PurchaseOrderLine>
      <StockCode>
        <xsl:value-of select="ITEM" />
      </StockCode>
      <OrderQty>
        <xsl:value-of select="QTY" />
      </OrderQty>
    </StockLine>
  </xsl:template>

</xsl:stylesheet>

在样本输入上运行时，会产生：

<PostPurchaseOrder>
  <OrderHeader>
    <Supplier>LIY0001</Supplier>
    <CustomerPoNumber>LIY0001-2013-02-14</CustomerPoNumber>
    <OrderDate>2013-02-14</OrderDate>
    <Warehouse>A4</Warehouse>
  </OrderHeader>
  <OrderDetails>
    <StockLine>
      <PurchaseOrderLine>1</PurchaseOrderLine>
      <StockCode>5021616</StockCode>
      <OrderQty>528</OrderQty>
    </StockLine>
    <StockLine>
      <PurchaseOrderLine>2</PurchaseOrderLine>
      <StockCode>5021816</StockCode>
      <OrderQty>222</OrderQty>
    </StockLine>
  </OrderDetails>
  <OrderHeader>
    <Supplier>WOR0001</Supplier>
    <CustomerPoNumber>WOR0001-2013-02-14</CustomerPoNumber>
    <OrderDate>2013-02-14</OrderDate>
    <Warehouse>A4</Warehouse>
  </OrderHeader>
  <OrderDetails>
    <StockLine>
      <PurchaseOrderLine>9</PurchaseOrderLine>
      <StockCode>650616</StockCode>
      <OrderQty>129</OrderQty>
    </StockLine>
  </OrderDetails>
  <OrderHeader>
    <Supplier>WOR0001</Supplier>
    <CustomerPoNumber>WOR0001-2013-02-14</CustomerPoNumber>
    <OrderDate>2013-02-14</OrderDate>
    <Warehouse>A5</Warehouse>
  </OrderHeader>
  <OrderDetails>
    <StockLine>
      <PurchaseOrderLine>1</PurchaseOrderLine>
      <StockCode>650610</StockCode>
      <OrderQty>129</OrderQty>
    </StockLine>
  </OrderDetails>
</PostPurchaseOrder>

您可以使用XSLT 2.0实现以下目标：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" exclude-result-prefixes="xs fn">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

    <xsl:template match="rows">
        <PostPurchaseOrder>
            <!-- Generate Orders with OrderHeader -->
            <xsl:for-each-group select="row" group-by="SUPPLIER">
                <Orders>
                    <OrderHeader>
                        <Supplier><xsl:value-of select="SUPPLIER" /></Supplier>
                        <CustomerPoNumber><xsl:value-of select="CUST_PO_NO" /></CustomerPoNumber>
                        <OrderDate><xsl:value-of select="RELEASE_DATE" /></OrderDate>
                        <Warehouse><xsl:value-of select="DESTWHS" /></Warehouse>
                    </OrderHeader>
                    <!-- Generate OrderDetails -->
                    <OrderDetails>
                        <!-- Generate StockLine -->
                        <xsl:for-each select="current-group()">
                            <StockLine>
                                <PurchaseOrderLine><xsl:value-of select="LINE_ITEM_NO" /></PurchaseOrderLine>
                                <StockCode><xsl:value-of select="ITEM" /></StockCode>
                                <OrderQty><xsl:value-of select="QTY" /></OrderQty>
                            </StockLine>
                        </xsl:for-each>
                    </OrderDetails>
                </Orders>
            </xsl:for-each-group>
        </PostPurchaseOrder>
    </xsl:template>
</xsl:stylesheet>
