extract

I'm learning about scrapy and I'm trying to extract all links that contains: " http://lattes.cnpq.br/andasequenceofnumbers " , example: http://lattes.cnpq.br/0281123427918302 But I don't know what is the page on the web site that contains these information. For example this web site: http://www.ppgcc.ufv.br/ The links that I want are on this page: http://www.ppgcc.ufv.br/?page_id=697 What could I do? I'm trying to use rules but I don't know how to use regular expressions correctly. Thank you 1 EDIT---- I need search on all pages of the main (ppgcc.ufv.br) site the kind of links (http://lattes

I've seen some posts like this, but not exactly what I want to do. How can I extract and delete URL links, and then remove them from plain text. Example: "Hello!!, I love http://www.google.es". I want extract the "http://www.google.es", save it on a variable, and then, remove it from my text. Finally, the text has to be like that: "Hello!!, I love". The URLs usually are the last "word" of the text, but not always. Perhaps you want URI::Find , which can find URIs in arbitrary text. The return value from the code reference you give it produces the replacement string for the URL, so you can just

Recently I encountered the following problem in my R code. In a function, accepting a data frame as an argument, I needed to add (or replace, if it exists) a column with data calculated based on values of the data frame's original column. I wrote the code, but the testing revealed that data frame extract/replace operations , which I've used, resulted in a loss of the object's special (user-defined) attributes . After realizing that and confirming that behavior by reading R documentation ( http://stat.ethz.ch/R-manual/R-patched/library/base/html/Extract.html ), I decided to solve the problem

I have a huge Excel spreadsheet that contains records of Customers where each column is a field. There's a field called Demographics which contains survey results of Customers and it's entirely in XML format. That is each Customer has a survey result on their demographic info like Gender, Marital Status, Income, Age, etc. which is given in XML format. It is notable that the whole XML is like a big chunk of text in a cell of the spreadsheet which I can't use to analyze the data. The problem is now I want to extract the demographic data of each Customer and present it as fields in the same

I was using VirtualBox on my PC( WIN 7 ) I managed to View some files in my .VDI file.. How can I open or view the contents of my .vdi file and retrieve the files from there? You can mount partitions from .vdi images using qemu-nbd : sudo apt install qemu-utils sudo modprobe nbd vdi="/path/to/your.vdi" # <<== Edit this sudo qemu-nbd -c /dev/nbd0 "$vdi" # view partitions and select the one you want to mount. # Using parted here, but you can also use cfdisk, fdisk, etc. sudo parted /dev/nbd0 print part=nbd0p2 # <<== partition you want to mount sudo mkdir /mnt/vdi sudo mount /dev/$part /mnt/vdi

In the DB I am working with, I want to select only the year from a specific TimeStamp field. In particular, I'm hoping to select the unique years from this database column. For instance, if all of the timestamps in the field "ModifyTimeStamp" are either from the year 2002 or the year 2006, I would like returned simply a result of '2002' and '2006'. If this is impossible, I'd be content with getting a result of a bunch of '2002's mixed with '2006's and would parse it later. All I've been able to get working so far is "Select ModifyTimeStamp from Table" - all my attempts to parse have failed. I

I'm working with Apache's FTPClient class in the Apache commons net library. Sadly it doesn't implement an interface for most of the functionality which makes testing classes which use it tricky. So, I thought I'd create my own class which wrappers this one and implements an interface. Anyway that's the background. My question is, is it possible in Eclipse to generate an Interface (similiar to Refactor->Extract Interface) but for 3rd party code sitting in a jar file? Just to clarify, I'm not looking for FTPClient to now implement the new interface, but to create an interface which mimics the
