【记录】尝试使用PDFMiner将不可复制的PDF转换为文本或HTML

【背景】

折腾:

【未解决】将不可拷贝复制的PDF中的表格数据导出并转换为xml格式数据

期间,打算去试试使用PDFMiner去把PDF,且是个加了密,不可拷贝的PDF,看看能否转换为文本或HTML。

 

【折腾过程】

1.找到主页:

PDFMiner

去:

https://pypi.python.org/pypi/pdfminer/

下载:

pdfminer-20131113.tar.gz

2.解压后去安装:

然后再去试试。

然后在:

中找到:

pdf2txt.py

然后去试试:

3.结果竟然出错:

5.然后再去试试,看看能否用PDFMiner去解密,结果没有找到这些选项。。。

 

【总结】

最终放弃使用PDFMiner,暂时由于该程序有bug,无法用其将pdf转换为html或文本。



One Thought on “【记录】尝试使用PDFMiner将不可复制的PDF转换为文本或HTML

  1. 最新版的PDFMINER能够破解空字符的加密PDF,但如果是有密码的话.估计你怎么折腾都比较困难.没有解密算法的话,这些PDF是不可能直接转换的.
