使用XSLT在XML中连接来自多个节点的值

这是一个测试XML，不是原始XML。我需要拉这些博客网站只有博客ID存在于bloggrs块是否可以只使用XSLT？我认为不可能

<root>
<bloggers>
<name bloggerId = "1">Jacob Sebastian</name>
<name bloggerId = "2">Adam Machanic</name>
<name bloggerId = "3">Pinal Dave</name>
<name bloggerId = "4">Steve Jones</name>
<name bloggerId = "5">Michael Coles</name>
</bloggers>
<blogs>
<url bloggerId = "1">http://www.sqlblog.com/adam_machanic </url>
<url bloggerId = "2">http://www.sqlauthority.com </url>
<url bloggerId = "3">http://www.beyondrelational.com </url>
<url bloggerId = "4">http://www.sqlblog.com/michael_coles </url>
<url bloggerId = "5">http://www.sqlservercentral.com/blogs/steve_jones </url>
<url bloggerId = "6">http://www.cnn.com/belief </url>
<url bloggerId = "7">http://www.yahoo.com/360 </url>
</blogs>
</root>

---

此列表将排除站点6和7，因为这些bloggers编号在bloggers中不存在。

甚至xpath也足够了：

//blogs/url[@bloggerId=//bloggers/@bloggerId]

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        <table border="1">
            <xsl:apply-templates select="//url" />
        </table>
    </xsl:template>

    <xsl:template match="url">
        <xsl:variable name="id" select="@bloggerId" />

        <xsl:if test="count(//bloggers//name[@bloggerId = $id]) &gt; 0">
            <tr>
                <td>
                    <xsl:value-of select="//bloggers//name[@bloggerId = $id]" />
                </td>
                <td>
                    <xsl:value-of select="." />
                </td>
            </tr>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

---

这个简短而简单的（无

xsl:variable

，无

xsl:if

）转换：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/*">

感谢大家回答这个问题。我相信所有答案都是正确的。在问之前，我确信这是不可能的，但我还是问了：）很高兴我问了。
