XSL XML解析，转换，属性

Question

这是我的XML文件。我想使用XSLT将它们转换为浏览器可读信息

<artist rank="1">
<name>Dream Theater</name>
<playcount>1438</playcount>
<mbid>28503ab7-8bf2-4666-a7bd-2644bfc7cb1d</mbid>

<image size="large">http://userserve-ak.last.fm/serve/126/5535004.jpg</image>
</artist>
<artist rank="2">
<name>Miles Davis</name>
<playcount>748</playcount>

这是我在XSL文件中的解决方案:

  <td><xsl:value-of select="image"/></td>
  <td><xsl:value-of select="image"/></td>
  <td><xsl:value-of select="image"/></td>

但是你可以看到艺术家的排名是1,2,3…如果我输入value-of select="image"它只能从XML文件中读取第一个图像…那么，如何将每个艺术家的排名1、2、3转换为合适的XSL呢?

Answer 1

你需要添加一个<xsl:for-each select='image'>来获取每个图像，否则你只会继续获得第一个匹配。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<xsl:template match="/">
<table>
<xsl:for-each select='/xml/artist'>
<xsl:sort order="ascending" data-type="number" select="@rank"/>
<tr>
    <td><xsl:value-of select='name'/></td>
    <xsl:for-each select='image'>
        <td><xsl:value-of select='.'/></td>
    </xsl:for-each>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
