问题描述

我正在尝试使用Apache FOP使用XML数据和XSL样式表创建PDF，但我不断收到以下错误消息

I am trying to use Apache FOP to create a PDF using XML data and a XSL stylesheet but I keep getting the following error

org.apache.fop.apps.FOPException: org.apache.fop.fo.ValidationException: "{ http://www.w3.org/1999/XSL/Format }块不是有效的孩子 "fo:root"！ (没有可用的上下文信息) javax.xml.transform.TransformerException: org.apache.fop.fo.ValidationException: "{ http://www.w3.org/1999/XSL/Format }块不是有效的孩子 "fo:root"！ (没有可用的上下文信息)

org.apache.fop.apps.FOPException: org.apache.fop.fo.ValidationException: "{http://www.w3.org/1999/XSL/Format}block" is not a valid child of "fo:root"! (No context info available) javax.xml.transform.TransformerException: org.apache.fop.fo.ValidationException: "{http://www.w3.org/1999/XSL/Format}block" is not a valid child of "fo:root"! (No context info available)

奇怪的是，当我在本地Windows机器上对其进行测试时，它工作正常，但是当我尝试在Debian服务器上进行同样的操作时，却出现此错误.

The strange thing is that it works fine when I was testing it on my local Windows machine but when I tried to do the same on Debian server I was getting this error.

我正在命令行上执行以下操作

I am doing the following on the command line

fop -c fop_config.xml -xml /tmp/fop4IwJKZ -xsl stylesheet.xsl -pdf pdf.pdf

下面是我的XML:

更新:我已经检查了两台机器上的XSLT进程，它们是相同的.我还已经将两台计算机上的XML + XSL转换为XLS:FO，并且两个文件都相同.

UPDATE: I have checked the XSLT Process on both machines and they are the same. I have also converted the XML + XSL on both machines to XLS:FO and both files are the same.

推荐答案

我将您的XML和XSL文件与

I use your XML and XSL file with

C:\Users\User>cd Documents
C:\Users\User\Documents>cd fop-1.0
C:\Users\User\Documents\fop-1.0>fop -xsl stovfl17548663.xsl -xml stovfl17548663.xml -pdf stovfl17548663.pdf
