使用XSLT将EDI XML转换为XML

<!-- EDI XML -->
<EDI>
  <Transaction>
    <ID>123456</ID>
    <Date>2022-01-01</Date>
    <Items>
      <Item>
        <Name>Product A</Name>
        <Quantity>10</Quantity>
      </Item>
      <Item>
        <Name>Product B</Name>
        <Quantity>5</Quantity>
      </Item>
    </Items>
  </Transaction>
</EDI>

<!-- XSLT 转换规则 -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>

  <xsl:template match="/">
    <Order>
      <OrderID>
        <xsl:value-of select="EDI/Transaction/ID"/>
      </OrderID>
      <OrderDate>
        <xsl:value-of select="EDI/Transaction/Date"/>
      </OrderDate>
      <Items>
        <xsl:for-each select="EDI/Transaction/Items/Item">
          <Item>
            <Name>
              <xsl:value-of select="Name"/>
            </Name>
            <Quantity>
              <xsl:value-of select="Quantity"/>
            </Quantity>
          </Item>
        </xsl:for-each>
      </Items>
    </Order>
  </xsl:template>
</xsl:stylesheet>

<!-- 转换后的XML -->
<Order>
  <OrderID>123456</OrderID>
  <OrderDate>2022-01-01</OrderDate>
  <Items>
    <Item>
      <Name>Product A</Name>
      <Quantity>10</Quantity>
    </Item>
    <Item>
      <Name>Product B</Name>
      <Quantity>5</Quantity>
    </Item>
  </Items>
</Order>
