如何读取没有列线或正确缩进的文本文件 [英] How to read a text file without column lines or properly indented
本文介绍了如何读取没有列线或正确缩进的文本文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个文本文件，它是从选举卷pdf文件创建的，其中3个人数据放在同一行。
我想得到每个来自文本文件的人员数据。我面临的问题是，在人行的名称之后，如果名称太长，则一行保持为空。在文本文件中假设下一行有第三人名，那么如何让读者识别数据是第三人并相应地分配它。
任何帮助这将是样本数据：
I have a text file which is created from electoral roll pdf file in which 3 persons data is placed on a same line.
I would like to get each persons data from the text file. Problem I m facing here is that after the name of person line, one line is kept empty incase the name is too long. Here in text file suppose 3rd persons name comes on next line then how to make reader identify that the data is of 3rd person and assign it accordingly.
Any help on this matter will be helfull.
Here is the sample data:
1 EPIC NO: XYZZ989898 2 EPIC NO: XYZZ989898 3 EPIC NO: XYZZ989898
Name : abcd xyz Name : abcd xyz Name : abcd lmno
xyz
Husband's abcdefghijklm xyz Father's abcd xyz Father's abcd xyz
Name: Name: Name:
House No: - House No: - House No: -
Age: 44 Sex: Female Age: 24 Sex: Male Age: 21 Sex: Female
这里是编码，我必须指定2个变量值（r和l），以允许读者将其识别为列的边界，但它不起作用，因为不同的文件将具有不同的缩进，我将不得不一次又一次地指定它。
here is the coding which i have to specify 2 variables value (r and l) to allow reader to identify it as boundries for columns but it is not working as different files will have different indentations and i'll have to specify it again and again.

As Richard MacCutchan says, its a matter of reading each line one at a time ... and the good bit is, you have the keywords to tell you where the information should be - so you need to write a parser/state machine looking for the ’tokens’ which would be for example ’Name :’. You can extract the name data from the name line, but I would also be marking/noting the start column positions. The End column positions are the next Token Start position minus 1, remembering <eol> (end-of-line) is also a token
The Name second line isnt hard - there are no ’House No:’ tokens on that line, so it must be the continuation part of the Name line - so, you have the column positions for the name data, the first and second columns are empty, the third column contains ’xyz’, which must be added to the data for the third name
I think you need a generalised set of routines to handle this, in the guise of a parser/state machine
