我尝试在将其写入csv文件之前使用我的pdfform-scraper-script删除一些隐藏的输入。但我一直收到标题中提到的错误。相关的代码是:
import glob
import os
import sys
import csv
from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdftypes import resolve1
path = 'C:\Users\Wonen\Downloads\Test'
for filename in glob.glob(os.path.join(path, '*.pdf')):
fp = open(filename, 'rb')
#read pdf's
parser = PDFParser(fp)
doc = PDFDocument(parser)
#doc.initialize() # <<if password is required
fields = resolve1(doc.catalog['AcroForm'])['Fields']
row = []
for i in fields:
field = resolve1(i)
name, value = field.get('T'), field.get('V')
#removing 'hidden enter'
if value == None:
print 'ok'
elif value == NotImplementedError:
print 'ok'
elif '\n' in value:
value.replace('\n',' ')
elif '\r' in value:
value.replace('\r',' ')
row.append(value)
writer.writerow(list(reversed(row)))
完整错误(+输出)是:
OK
确定
Traceback(最近一次调用最后一次):文件 &#34; C:\ Python27 \ Scripts \ test3.py&#34;,第37行,in elif&#39; \ n&#39; in value:TypeError:类型&#39; PSLiteral&#39;的参数是不可迭代的
有谁知道如何解决这个问题?
答案 0 :(得分:0)
不知道输入文件的内容很难猜到。我认为问题在于,在调用field.get('V')
来解决此问题时,您会获得一些非字符串值我建议您将value
更改为字符串。
试试这样:
if value == None:
print 'ok'
elif value == NotImplementedError:
print 'ok'
elif '\n' in str(value):
value = str(value)
value.replace('\n',' ')
elif '\r' in str(value):
value = str(value)
value.replace('\r',' ')
