使用xsl-fo将xml文档转换为PDF

Question

我想使用xsl-fo将xml文档转换为PDF。 当我尝试在左上角插入图像时，出现错误：Javax.xml.transform.TransformetException：org.apache.fop.fo.ValidationException：“ fo：external-graphic”不是“ fo：table”的有效子代-身体”！ （没有可用的上下文信息）。 有人可以向我解释我该怎么做，并告诉我如何在左上角插入图像吗？

xsl-fo代码：

Answer 1

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。 您应该改为插入<xsl:apply-templates select="data/players_data/player_data" /> 。
