extraction

I got the following string: String line = "#food was testy. #drink lots of. #night was fab. #three #four"; I want to take #food #drink #night #three and #four from it. I tried this code: String[] words = line.split("#"); for (String word: words) { System.out.println(word); } But it gives food was testy , drink lots of , nigth was fab , three and four . Orace split will only cuts the whole string at where it founds a # . That explain your current result. You may want to extract the first word of every pieces of string, but the good tool to perform your task is RegEx Here how you can achieve it:

I've got this xpath query: /html/body//tbody/tr[*]/td[*]/a[@title]/@href It extracts all the links with the title attribute - and gives the href in FireFox's Xpath checker add-on . However, I cannot seem to use it with lxml . from lxml import etree parsedPage = etree.HTML(page) # Create parse tree from valid page. # Xpath query hyperlinks = parsedPage.xpath("/html/body//tbody/tr[*]/td[*]/a[@title]/@href") for x in hyperlinks: print x # Print links in <a> tags, containing the title attribute This produces no result from lxml (empty list). How would one grab the href text (link) of a hyperlink

I'm doing an app to record a video. What I would like is that when the app is recording the video, each frame is also saved in an arraylist of RGB values in order to extract particular information from it. I know that the two processes (video recording and extraction of frames) are asynchronous, but this is not a problem: the process of extraction can finish after the video recording. Can someone tell me how I can extract the frames from the video? Thanks very much. Using the camera object you can override a function setPreviewCallback . from that function you would get an array of byte data.

I have complex DOM structure with dynamically changing values of the HTML id attributes. Selenium is returning "null" when I attempt to extract the values of the "custom" attributes. I need to extract the value of parentId (namely I need the "qqq-bbb", which is different on every reload) //Selenium(C#): // evaluates to "null" string someStringName = someIWebElement.GetAttribute("parentId"); //HTML tag (example): // in Chrome the parentId is visible and unique <g id="333-aaa" parentId="qqq-bbb"> Solution: (based on recommendation in comment#2). Issuing the following command returns as string

I really need help to extract Mircodata which is embedded in HTML5. My purpose is to get structured data from a webpage just like this tool of google: http://www.google.com/webmasters/tools/richsnippets . I have searched a lot but there is no possible solution. Currently, I use the any23 library but I can’t find any documentation, just only javadocs which dont provide enough information for me. I use any23's Microdata Extractor but getting stuck at the third parameter: "org.w3c.dom.Document in". I can't parse a HTML content to be a w3cDom. I have used JTidy as well as JSoup but the DOM objects

I wanted to know if it is possible to extract frames from a running Video in Android? I need to extract frames at regular intervals and send them for further processing. Would someone be able to find an answer for me?

Note that it's only supported since: API Level 10 . Nilesh Gangadhar You can use the code below: String SrcPath="/sdcard/Pictures/Video Task/"; MediaMetadataRetriever

What is the best way to extract text from a pdf? Phssthpok The CAM::PDF module is pretty useful for extracting text and maintaining some information about where it came from in the document. It installs /usr/local/bin/getpdftext.pl which demonstrates simple extraction. However, CAM::PDF can only read PDFs that are completely valid. If you are dealing with ill-formed PDFs, you may need a more lenient parser, such as pdftotext. It dumps foo.pdf to foo.txt, which you could then read into Perl. 来源： https://stackoverflow.com/questions/4730651/what-is-the-best-perl-module-to-extract-text-from-a-pdf
