【问题描述】：
我不明白为什么在尝试将 HTML 转换为 docx 时有时会出现空指针异常。
我使用带有所有依赖项的 docx4j 3.2.1，这是代码
private void ajoutDescription(String description, int maxWidth) {
if (description != null) {
if (description.length() > 1) {
description = formattageDescription(description, maxWidth);
try {
xHTMLImporter = new XHTMLImporterImpl(wordMLPackage);
wordMLPackage.getMainDocumentPart().getContent().addAll(xHTMLImporter.convert(description, null));
} catch (Docx4JException e) {
System.out.println("bug ajout desc");
System.out.println(description);
e.printStackTrace();
}
catch (NullPointerException e) {
System.out.println("bug ajout desc not Docx4j");
System.out.println(description);
e.printStackTrace();
}
}
}
}
这是 xHTMLImporter.convert(description, null) 中的错误和描述 arg
<html xmlns="http://www.w3.org/1999/xhtml">

<style type="text/css">p, ul, li, table, tr, td, font{font-family: Arial;font-size:120%}img{max-width:902px; height:auto;}</style>

我不知道如何解决这个问题。有些图片不会导致这个错误，但我不知道哪些会。
