格式错误的 XML/HTML 解析
我需要解析多个（读取大约 1600 个）HTML 页面，并从每个文件中提取以下标记的内容。
textarea name="line" cols="66" rows="5" class="textbox" id="line" style="font-size:12px;" onkeydown="textCounter()" onkeyup="textCounter(); storeCaret(this);" onselect="storeCaret(this);" onclick="storeCaret(this);">TEXT I WANT IS HERE
（这实际上是一个 html textarea 标签） 我原以为我可以使用 DOMparser 但文件包含太多错误，所以我从 stackoverflow 上的另一个问题中遇到了 JTidy，并且我尝试使用它......
但这似乎无法转换html 从任何页面转换为 XHTML，这样我就可以使用 DOM 解析器。
然后我想我可以使用正则表达式，但我找不到提取该文本所需的特定表达式，而且我还遇到了多个问题/答案，这些问题/答案说不要使用正则表达式来解析 HTML...
所以本质上我的问题是有什么为了从格式错误的 html 中获取我需要的文本，需要采取其他方法吗？
I need to parse a multiple(read approx 1600) HTML pages and pull out the contents of the following tag from each file.
textarea name="line" cols="66" rows="5" class="textbox" id="line" style="font-size:12px;" onkeydown="textCounter()" onkeyup="textCounter(); storeCaret(this);" onselect="storeCaret(this);" onclick="storeCaret(this);">TEXT I WANT IS HERE
(this is actually meant to be a html textarea tag)
I had thought I could use a DOMparser but the files contain too many errors, and so I came across JTidy, from another question here on stackoverflow, and I have tried to use that...
But that doesnt seem to be able to convert the html from any of the pages into XHTML so I can then use a DOM parser.
I then thought I could use regex, but I couldnt quite find the particular expression needed to pull that text, and also I came across multiple questions/answers which said NOT to use regex to parse HTML...
SO essentially my question is there any other approach to take in order to get the text I need from a malformed html?

您应该能够直接使用 JTidy 解析您的文档，而无需将它们转换为 XHTML。不久前，我曾多次这样做过，但它对我来说效果很好，而且 HTML 相当丑陋。
编辑： 上次我需要解析 HTML 文件时，我看到的另一个选项是 TagSoup。由于其 GPL 许可证，我无法在商业产品中使用它，但如果您只需要此功能作为内部工具，它可能适合您
You should be able to parse your documents wit JTidy directly, without having to convert them to XHTML. I did it on several occasions, granted a while ago, but it worked for me fine and with quite ugly HTML.
EDIT: Another option that I looked at, last time I needed to parse HTML files, was TagSoup. I couldn't use it in a commercial product because of its GPL licence, but if you just need this functionality as an internal tool, it might work for you
