I have the following code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" />
<xsl:key name="categories" match="Category" use="." />
<xsl:key name="clients" match="Category" use ="Category/Client" />
<xsl:template match="/">
<ul id="red" class="treeview-red">
<xsl:for-each select="/Promotions/Promotion/Category[
generate-id(.) = generate-id(key('categories', .)[1])
]">
<xsl:variable name="cname" select="." />
<li>
<span>
<xsl:value-of select="$cname" />
</span>
<xsl:for-each select="/Promotions/Promotion[Category=$cname]">
<ul>
<li>
<span>
<xsl:value-of select="Client" />
</span>
</li>
<ul>
<li>
<span>
<xsl:value-of select="Title" />
</span>
</li>
</ul>
</ul>
</xsl:for-each>
</li>
</xsl:for-each>
</ul>
</xsl:template>
</xsl:stylesheet>
我的XML:
<Promotions>
<Promotion>
<Category>Arts & Entertainment</Category>
<Client>Client 1</Client>
<Title>Get your Free 2</Title>
</Promotion>
<Promotion>
<Category>Arts & Entertainment</Category>
<Client>Client 1</Client>
<Title>Get your Free 4</Title>
</Promotion>
<Promotion>
<Category>Arts & Entertainment</Category>
<Client>Client 1</Client>
<Title>Get your Free 5</Title>
</Promotion>
<Promotion>
<Category>Community & Neighborhood</Category>
<Client>Client 2</Client>
<Title>Get your Free 1</Title>
</Promotion>
<Promotion>
<Category>Education</Category>
<Client>Client 3</Client>
<Title>Get Your Free 3</Title>
</Promotion>
</Promotions>
它会输出以下内容:
<ul id="red" class="treeview-red">
<li><span>Arts & Entertainment</span><ul>
<li><span>Client 1</span></li>
<ul>
<li><span>Get your Free 2</span></li>
</ul>
</ul>
<ul>
<li><span>Client 1</span></li>
<ul>
<li><span>Get your Free 4</span></li>
</ul>
</ul>
<ul>
<li><span>Client 1</span></li>
<ul>
<li><span>Get your Free 5</span></li>
</ul>
</ul>
</li>
<li><span>Community & Neighborhood</span><ul>
<li><span>Client 2</span></li>
<ul>
<li><span>Get your Free 1</span></li>
</ul>
</ul>
</li>
<li><span>Education</span><ul>
<li><span>Client 3</span></li>
<ul>
<li><span>Get Your Free 3</span></li>
</ul>
</ul>
</li>
</ul>
我希望先按类别分组,然后对于每个类别再按客户进行分组输出结果。如果您有任何想法,请告诉我,非常感谢。
<ul id="red" class="treeview-red">
<li><span>Arts & Entertainment</span><ul>
<li><span>Client 1</span></li>
<ul>
<li><span>Get your Free 2</span></li>
</ul>
<ul>
<li><span>Get your Free 4</span></li>
</ul>
<ul>
<li><span>Get your Free 5</span></li>
</ul>
</ul>
</li>
<li><span>Community & Neighborhood</span><ul>
<li><span>Client 2</span></li>
<ul>
<li><span>Get your Free 1</span></li>
</ul>
</ul>
</li>
<li><span>Education</span><ul>
<li><span>client 3</span></li>
<ul>
<li><span>Get Your Free 3</span></li>
</ul>
</ul>
</li>
</ul>
基本上,按类别分组后,我只想在该类别下看到一个客户以及该客户在该类别中的每个促销活动。
