我尝试将报告导出为 XML 格式的 PDF，其中一列包含超过 100,000 个字符。导出失败，我收到 SAXException。我们使用 fop 0.95。

如果您遇到过此类问题，请帮助我。

这似乎在 FOP FAQ 中进行了讨论:

This exception is usually a follow-up error after another exception. Sometimes the original exception gets swallowed by Xalan's default ErrorListener (should be fixed in the latest Xalan release).

解决方法是在 Transformer 上设置显式 ErrorListener。
