Question

我的问题是我想按模型为每个项目分组，但我只想加载单个实体的详细信息

<Search-Request search-term="1 tb">
    <Items>
        <Item href="SEA1TBST31000524AS.jpg" model="ST31000524AS">
            <Name>Seagate Hard disk 1TB ST31000524AS 3.5"</Name>
            <Price>60.50</Price>

因此上面的XML将包含遇到的第一个元素

<Item href="SEA1TBST31000524AS.jpg" model="ST31000524AS">
         <Name>Seagate Hard disk 1TB ST31000524AS 3.5"</Name>
         <Manufacturer>Seagate</Manufacturer>  
</Item>

我想知道我是否可以选择两种价格，然后只选择要显示的最佳价格。其他价格可以列在工具提示中。例如。

并且明智地将它们结合起来

我知道这不是一件简单的事。

我很容易就每个项目都列出了每个项目。

但我希望它看起来更精致，但要求是没有使用高级语言代码所以我问你们这是否可能。

如果可能的话，可以将项目分成多个页面，例如每页显示5个。虽然这不是必要的，但我只是想知道是否有可能。

Answer 1

我确实找到了如何做我需要的事情

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="Price">
<xsl:if test="position() = 1">
<li><xsl:value-of select="."/></li>
</xsl:if>
</xsl:template>

<xsl:template match="Search-Request">
<html>
<body>
      <xsl:for-each-group select="Items/Item" group-by="@model">
        <xsl:sort select="@model" data-type="text" order="descending"/>
        <p><xsl:value-of select="@model"/></p>
        <ol>
<xsl:apply-templates select="current-group()/Price">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates>
        </ol>
      </xsl:for-each-group>
</body>
</html>
</xsl:template>

</xsl:stylesheet>

现在我只需要应用剩下的元素就可以完成了。
