Question

我正在尝试使用以下命令中的apache-fop生成pdf。

C:\fop-1.0-bin\fop-1.0>fop -xml sample1.xml -xsl xsl-fo.xsl -pdf sample2.pdf

我的xml看起来像这样

<?xml version="1.0" encoding="iso-8859-1"?>
<service>
    <serviceId>11111</serviceId>
    <openDate>2012-02-16</openDate>
    <closeDate>2012-02-16</closeDate>
    <description>INSPECT MACHINE</description>
    <repairCost>$266.76</repairCost>
</service>

我的xsl-fo xslt文件看起来像这样

<?xml version="1.0" encoding="UTF-8"?>

Answer 2

它可以像案件的问题一样简单吗？您的示例XML使用<service>作为根标记，但您有<xsl:template match="Service">（大写字母S）。

Answer 3

FOP不支持自动表格布局，而是使用固定的表格布局

FOP不支持自动布局，因为页面具有静态宽度[A4，A3 ...] 仅在html rendring中支持自动模式，因为页面大小可能会更改（取决于分辨率，调整窗口大小...）见：

http://mail-archives.apache.org/mod_mbox/xmlgraphics-fop-dev/200510.mbox/%3C20051005124250.8A19A21E@ajax.apache.org%3E

http://wiki.apache.org/xmlgraphics-fop/Troubleshooting/CommonLogMessage

注意：为避免出现警告，您应指定table-layout =“fixed”，并在定义列widht时使用width =“100％”和“*”
