Question

我需要一些关于这个XSLT的帮助。它正在按照它的方式工作，但是我已经改变了要求... :-)而且我需要修改它以给我预期的输出。我正在寻找一些指导和帮助。

说明：我有像这样的源码xml

<XML>
  <Attributes>
    <Attribute>
    <Name/>
    <Type/>
    <Value/>
    <FromIM/>
    <collection/>
      <Path />
    </Attribute>
</Attributes>
</XML>

在上面的xml中，我需要查看节点“Type”并按类型对它们进行分组。例如，如果我有5个属性，其中Type是常见的，4个属性，其中Type是category，3个属性，其中Type是Complex，那么将它们分组为这样。

<?xml version="1.0" encoding="utf-8"?>
<Data Schema="XML A">
  <Items>
    <Item id="" shortname="FT123" longname="FT123" categorypath="FamilyName//DepartmentName//GroupName" type="Product">
      <Attributes type="common">
        <Attr name="common 1" value="1" path=""/>
        <Attr name="common 2" value="2" path=""/>
        <Attr name="common 3" value="3" path=""/>
        <Attr name="common 4" value="4" path=""/>
        <Attr name="common 5" value="4" path=""/>
        <Collection id="" name="Collection" path="">
          <Complex>
            <Attr name="UPC" value="Testing" valueKey="0" />
            <Attr name="Color" value="Yellow"  valueKey="0"/>
            <Attr name="Size" value="10"  valueKey="0"/>
          </Complex>
        </Collection>
      </Attributes>
      <Attributes type="category">
        <Attr name="category1" value="1" />
        <Attr name="category2" value="2" />
        <Attr name="category3" value="3" />
        <Attr name="category4" value="4" />
      </Attributes>
     </Item>
    </Items>
 </Data>

从上面可以看出，我是第一组共同的＆amp;类别并为常见的Complex创建一个组集合。这工作正常（虽然我正在使用Iteration ......： - ））

问题是我只为1个属性创建了一个Complex，其中Name = Collection并且它是硬编码的。但是，新要求是我为另一个属性创建了一个复杂的集合，其中name = Cost。

这是我遇到问题的地方。我怎样才能做到这一点。下面是示例源和输出xml和XSLT。在此先感谢。

源XML：

预期输出 我需要2个收集节点，我需要输入当前日期。注意在Collection Node中我可以有多个Complex节点。但是，在Cost中，我只有1个Complex节点。

<?xml version="1.0" encoding="utf-8"?>
<Data Schema="XML A">

    <Item id="" shortname="FT123" longname="FT123" sku="FT123" action="ADD" categorypath="FamilyName//DepartmentName//GroupName" type="Product">
      <Attributes type="common">
        <Attr name="Buyer ID" value="Lee" path="" action="ADD" />
        <Attr name="Enviornment" value="Dev" path="" action="ADD" />
        <Attr name="Retail" value="" path="" action="ADD" />

虽然远非完美，但这里有一个样式表可以产生你想要的输出。我不确定修复每个复杂的属性或修复集合的程度。如果这有帮助，请告诉我。
