因此，我阅读了 pdf 的每一页并将每个 xml 提取附加到一个字符串变量中。使用Page.get_text(“xml”). 文本输出由许多单元组成

<page id="page0" width="595.276" height="841.89">\n<block bbox="84.95639 235.90979 382.4564 316.3398">\n<line bbox="84.96 235.90979 382.4564 278.3298" wmode="0" dir="1 0">\n<font name="AkkuratPro-Bold" size="35">

我知道这些是文本周围的边界框，并且在文档中指定这些最好使用 lxml 解析。所以我尝试了下面的实现方式。

from lxml import etree

root = etree.fromstring(texts)

并得到以下错误：

Traceback (most recent call last):

我真的很想知道当前实现 lxml 和使用边界框从 pdf 文档中获取文本的方式。
