RuntimeWorkerException: Invalid nested tag head found, expected closing tag meta
提问by Drazen Bjelovuk
I'm using iText in order to convert html into a pdf, but I keep getting a RuntimeWorkerException thrown at parseXHtml. Here's my code:
我正在使用 iText 将 html 转换为 pdf，但我一直在parseXHtml. 这是我的代码：
Document tempDoc = new Document();
PdfWriter pdfWriter = PdfWriter.getInstance(tempDoc, out);
tempDoc.open();
XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, tempDoc, new ByteArrayInputStream(html.getBytes()));
tempDoc.close();
I'm not too familiar with the differences between HTML and XHTML, so I'm at a bit of a loss as to how I should handle this. Here's the html source if it helps.
我不太熟悉 HTML 和 XHTML 之间的差异，所以我不知道应该如何处理这个问题。如果有帮助，这里是 html 源代码。

The error message is pretty clear, you have a <meta>tag in the header that isn't closed which is valid in HTMLbut not XHTMLwhich is what you are parsing it as. You need to close those, <meta ... />
错误消息非常清楚，您<meta>在标头中有一个未关闭的标记，该标记有效HTML但不是XHTML您正在解析的标记。你需要关闭那些，<meta ... />

If you are using XMLWorkerHelper make sure you end image, breakpoint tag properly like />.
如果您使用 XMLWorkerHelper，请确保结束图像，断点标记正确，如 />。

For a similar error message -
对于类似的错误消息 -
invalid nested tag body found, expected closing tag meta
invalid nested tag body found, expected closing tag meta
turned out the XHTML I was parsing had a <script>section at the bottom, that contained JS code, something like:
结果我正在解析的 XHTML<script>在底部有一个部分，其中包含 JS 代码，例如：
<script>
function my_func(var) {
...
}
</script>
After removing that code (with simple string manipulations), I was able to get the .parseXHtmlto work without issues.
删除该代码（使用简单的字符串操作）后，我能够.parseXHtml正常工作。

you have to close each and every tag. example- in HTML
你必须关闭每一个标签。示例 - 在 HTML 中
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
is valid.
已验证。
But in xhtml you have to use
但是在 xhtml 中你必须使用
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"></meta>
So close each and every tag in html (example meta tag, col tag, img tag etc).
所以关闭 html 中的每个标签（例如元标签、col 标签、img 标签等）。

Remember to close all meta tags
记得关闭所有元标签
<meta ... />
