我有以下xml：

<?xml version="1.0"?>
<PurchaseOrder xmlns="http://www.codesmithtools.com/purchaseorder">
  <ShipTo Name="Eric J. Smith">
    <Line1>123 Test Dr.</Line1>
    <City>Dallas</City>
    <State>TX</State>
    <Zip>75075</Zip>
  </ShipTo>
  <OrderDate>05-01-2003</OrderDate>
  <Items>
    <OrderedItem>
      <ItemName>Item #1</ItemName>
      <Description>Item #1 Description</Description>
      <UnitPrice>5.45</UnitPrice>
      <Quantity>3</Quantity>
      <LineTotal>16.35</LineTotal>
    </OrderedItem>
    <OrderedItem>
      <ItemName>Item #2</ItemName>
      <Description>Item #2 Description</Description>
      <UnitPrice>12.75</UnitPrice>
      <Quantity>8</Quantity>
      <LineTotal>102.00</LineTotal>
    </OrderedItem>
  </Items>
  <SubTotal>45.23</SubTotal>
  <ShipCost>5.23</ShipCost>
  <TotalCost>50.46</TotalCost>
</PurchaseOrder>

我有以下 codesmith 模板：

    <%@ XmlProperty Name="MyPurchaseOrder" Schema="PurchaseOrder.xsd" Default="SamplePurchaseOrder.xml" %>

    PurchaseOrder:
        Address:
            Name: <%= MyPurchaseOrder.ShipTo.Name %>
            Line1: <%= MyPurchaseOrder.ShipTo.Line1 %>
            City: <%= MyPurchaseOrder.ShipTo.City %>
            State: <%= MyPurchaseOrder.ShipTo.State %>
            Zip: <%= MyPurchaseOrder.ShipTo.Zip %>
        OrderDate: <%= MyPurchaseOrder.OrderDate %>
        Items:
            <% for (int i = 0; i < MyPurchaseOrder.Items.Count; i++) { %>
            <%= i %>:
                ItemName: <%= MyPurchaseOrder.Items[i].ItemName %>
//Here I need to traverse to the parent and print the City
                Description: <%= MyPurchaseOrder.Items[i].Description %>
                UnitPrice: <%= MyPurchaseOrder.Items[i].UnitPrice %>
                Quantity: <%= MyPurchaseOrder.Items[i].Quantity %>
                LineTotal: <%= MyPurchaseOrder.Items[i].LineTotal %>
            <% } %>
        SubTotal: <%= MyPurchaseOrder.SubTotal %>
        ShipCost: <%= MyPurchaseOrder.ShipCost %>
        TotalCost: <%= MyPurchaseOrder.TotalCost %>

当我遍历项目时，我需要打印地址的城市。本质上，我如何遍历到父级（或父级的父级）？

在您的示例中更改此行：

//Here I need to traverse to the parent and print the City

对此：

<%= MyPurchaseOrder.ShipTo.City %>

由于您使用的所有“路径”都是绝对的（即从 开始MyPurchaseOrder），因此在这种情况下应该可以使用绝对路径（您不需要向上导航到父节点）。
