我正在尝试在我的fo文件[*]中跟踪以下错误。由于错误消息中没有上下文，因此我不明白我应该如何搜索根问题。
fo文件是从适当（至少每个XSD验证）docbook 5文件生成的，但是生成的fo文件是不正确的：
$ xmllint --nonet --noout --schema /usr/share/xml/docbook/schema/xsd/5.0/docbook.xsd source/docbook/part02/part02.xml
source/docbook/part02/part02.xml validates
一个人将如何从输入3.2m xml-fo文件中搜索根问题（DOCBOOC级别）？
$ du -sh bla.fo
3.2M bla.fo
[*]
$ fop -d bla.fo bla.pdf
