extract

I have HTML content stored in a variable. How do I extract data that is found between a set of common tags in the page? For example, I am interested in the data (represented by DATA kept between a set of tags which one line after the other: ... <td class="jumlah">*DATA_1*</td> <td class="ud"><a href="">*DATA_2*</a></td> ... And then I would like to store a mapping DATA_2 => DATA_1 in a hash Since it's HTML, you probably want the XPath module made for working with HTML, HTML::TreeBuilder::XPath . First you'll need to parse your string using the HTML::TreeBuilder methods. Assuming your webpage's

I'm trying to extract data from an OSM.PBF file using the python GDAL/OGR module. Currently my code looks like this: import gdal, ogr osm = ogr.Open('file.osm.pbf') ## Select multipolygon from the layer layer = osm.GetLayer(3) # Create list to store pubs pubs = [] for feat in layer: if feat.GetField('amenity') == 'pub': pubs.append(feat) While this little bit of code works fine with small.pbf files (15mb). However, when parsing files larger than 50mb I get the following error: ERROR 1: Too many features have accumulated in points layer. Use OGR_INTERLEAVED_READING=YES MODE When I turn this

If I use the ecdfplot() function of the latticeExtra package how do I get the actual values calculated i.e. the y-values which correspond to the ~x|g input? I've been looking at ?ecdfplot but there's not discription to it. For the usual highlevel function ecdf() it works with the command plot=FALSE but this does not work for ecdfplot() . The reason I want to use ecdfplot() rather than ecdf() is that I need to calculate the ecdf() values for a grouping variable. I know I could do this handish too but I'm quite convinced that there is a highroad too. Here a small expample u <- rnorm(100,0,1)

Let's dive into this, shall we? Ok, I need to write a script (I don't care what language, prefer something like Python or Javascript, but whatever works I will take time to learn). The script will access multiple URL's, extract text from each site and store it into a folder on my PC. (From there I am manipulating the data with Python, which I know how to do.) EDIT: Currently I am using python's NLTK module. Here is a simple version of my code: url = "<URL HERE>" html = urlopen(url).read() raw = nltk.clean_html(html) print(raw) This code works fine for both http and https , but not for

The manual on "extract" shows you can extract an array like: extract(array('one'=>1,'two'=>2)); into $one,$two... But the extract function doesn't return the variables. Is there a way to 'globalize' these variables? Maybe not using extract, but a foreach loop? EDIT: (explanation about what I'm trying to achieve) I have an array containing hundreds of output messages which I want to have accessible as variables efficiently. What I mean is that whenever I want to output a message, say: $englishMessages = array('helloWorld'=>'Hello World'); $spanishMessages = array('helloWorld'=>'Hola Mundo'); '

I'm writing a script to extract files from a zip archive into the directory that the script is located. Here's my code: $zip = new ZipArchive; if ($zip->open('latest.zip') === TRUE) { $zip->extractTo('.'); $zip->close(); unlink('installer.php'); echo 'it works!'; } else { echo 'failed'; } This works fine, but there's one problem. The zip contains an extra layer. (zip/directory/files) which extracts like this directory/files rather then just the files. Is there a way to remove this extra layer? Thanks for your help!
