pdf 格式到 csv python 或类似格式答案

【问题标题】：pdf form to csv python or similarpdf 格式到 csv python 或类似格式
【发布时间】：2014-12-03 14:57:27
【问题描述】：

我有一堆用 Adobe formscentral 创建的 pdf 表单 - 它们的格式都相同，我想将字段中的数据提取到 CSV 文件中。我（开始）对 python 有点熟悉，并尝试了一些库来通过 XML 标签提取文本。不过，我已经到了超出我的深度的地步：(

我已设法使用“pdfquery”和/或“beautifulsoup”阅读 PDF，但在任何地方都找不到简单的教程来帮助我将 pdf 解析为 csv/excel。我已经搜索过，似乎找不到任何完全相关的东西。我设法提取的 XML 树为我提供了字段名称的标签（见下文），但不知道如何从这里开始。有没有人有过这种操作的经验或能指出任何教程的方向。

感谢您的帮助！

谢谢

马蒂

【解决方案1】：

我更喜欢使用 lxml package，因为它有一个非常方便的 objectify 模块，可以让解析 XML 变得非常简单。

这是一个示例，展示了从 XML 中提取数据的几种方法：

from lxml import objectify

#----------------------------------------------------------------------
def parser(xml):
    """"""
    root = objectify.fromstring(xml)
    print root.LTPage.LTRect.attrib
    for item in root.LTPage.LTRect.getchildren():
        print item.tag
        print item.text
        print item.attrib
        print item.attrib["bbox"]

请注意，我修改了 XML 以具有正确的结束标记。您可能还会发现本教程很有用：
