Extract text of PDF without tool

由 你说的曾经没有我的故事 提交于 2020-01-25 10:18:06
问题 Currently I'm extracting the text of PDF's with the itextsharp tool (in VB.net). I'd like to be independent of other tools / libraries as I can't give them to others along my programm. Is there a solution (no .dll etc) in any programming language to quickly extract the text of a PDF? 回答1: Short answer: Of course there is a way of doing this. iText (alongside many other PDF libraries) are capable of doing it. So there is an algorithm for extracting text. Long answer: PDF is not a WYSIWYG

问题 Learning Python, I'm trying to make a web scraper without any 3rd party libraries, so that the process isn't simplified for me, and I know what I am doing. I looked through several online resources, but all of which have left me confused about certain things. The html looks something like this, <html> <head>...</head> <body> *lots of other <div> tags* <div class = "want" style="font-family:verdana;font-size:12px;letter-spacing:normal""> <form class ="subform">...</form> <div class = "subdiv1"

Tarring only the files of a directory

由 六月ゝ 毕业季﹏ 提交于 2020-01-17 02:28:37
问题 If I have a folder with a bunch of images, how can I tar ONLY the images and not the folder structure leading to the images without having to CD into the directory of images? tar czf images.tgz /path/to/images/* Now when images.tgz is extracted, the contents that are extracted are /path/to/images/... How I can only have the images included into the tgz file (and not the three folders that lead to the images)? 回答1: I know you can use --strip-components when untarring although I'm not sure if

Extracting small parts of large library (fx boost)

由 倖福魔咒の 提交于 2020-01-15 09:06:26
问题 I would like to know if there is an automated way to extract a small portion of a large C++ library. Let's say I only need boost::rational in some project. However entire boost 1.42 takes up 279 MiB! To keep my project "self-contained" (fx for some school work), I would like to be able to include boost::rational along with my own source. (The idea being, that my teacher should not have to install 1000's of libraries in advance in order to compile) I know this violates good practice, as it

Extract files to same folder as archive using recursive to search all directories

由 僤鯓⒐⒋嵵緔 提交于 2020-01-03 05:19:07
问题 I'm working on an automation task in PowerShell that extracts the contents of several .tar archives to their respective subfolders using recursion and the 7z.exe utility. Im running into an issue where the output dumps in my working directory instead of the subdirectory gci -r found the original tarball. So far I have: $files=gci -r | where {$_.Extension -match "tar"} foreach ($files in $files) { c:\7z.exe e -y $file.FullName } Advice on setting the working directory within the loop or 7z
