php - Parsing a Web Page's Source given URL -

-

By looking at the URL, how do you parse the source code of a certain web page? I was authored with source code, title and last time it was modified.

My idea is to parse the source code with file_get_contents (), then, for the author, I'll be able to & lt; Meta name = "author" content = "[...]"> and then remove what's in the content. For the title, I & lt; Title> [...] & lt; / Title> and remove what's inside. I'm not sure what I will do when finally it was modified.

Will these methods work?

You can use file_get_contents.

For example: 

  $ content = file_get_contents ('http://www.external-site.com/page.php');

Then the variable $ content will contain the contents of the external site.

If you need more information please let me know Thank you. Takes a call to the factory before the KV file is loaded, so you want the class to Are not yet in existence. As long as no clas...

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
