我想使用xsl-fo将我的xml文档转换为PDF。当我尝试在左上边距插入图像时，我收到一个错误： Javax.xml.transform.TransformetException：org.apache.fop.fo.ValidationException： “fo：external-graphic”不是“fo：table-body”的有效孩子！ （没有上下文信息）。有人可以解释一下我做错了什么，并告诉我如何在左上边缘插入图像？

答案 0 :(得分：2)
你有：
<xsl:template match="/">
(some stuff...)
<fo:table-body>
<xsl:apply-templates />
</fo:table-body>
(and so on...)
您的<xsl:apply-templates />将再次处理<logo>标记。您应该插入类似<xsl:apply-templates select="data/players_data/player_data" />的内容。
