I have the following Ruby code:
settings= hash.new
settings= batch.getPartialSettings
settings= batchSettings.merge(batch.getEntireSettings)
puts settings
The result is:
{"Resolution"=>"1024", "Applications"=>"Mozilla,IE,Chrome", "Programming"=>"Java,HTML"}
I want "Applications" to be sorted as:
"Applications"=>"Chrome,IE,Mozilla"
So, my final result should be:
{"Resolution"=>"1024", "Applications"=>"Chrome,IE,Mozilla", "Programming"=>"Java,HTML"}
unsorted_apps = settings['Applications']
sorted_apps = unsorted_apps.split(',').sort.join(',')
settings['Applications'] = sorted_apps

I am getting the amounts from an xml file but I need to sum them to check.
I am using Ruby on rails with the Nokogiri gem
Example from xml file:
<cfdi:Conceptos>
<cfdi:Concepto ClaveProdServ="15101514" NoIdentificacion="PL/762/EXP/ES/2015-16665610" Cantidad="52.967" ClaveUnidad="LTR" Descripcion="MAGNA (LT)" ValorUnitario="16.34" Importe="865.74">

</cfdi:Concepto>
I managed to obtain all the amounts and taxes with these line of code:
array = []
array_i = []
file = Nokogiri::XML(File.open(params[:consumption][:factura]))
doc_pass = file.xpath("//cfdi:Comprobante/cfdi:Conceptos/cfdi:Concepto")
doc_pass.each do |pass|
hash_importe = {}
hash_importe[:total] = pass['Importe']
array << hash_importe
end
doc_pass2 = file.xpath("//cfdi:Comprobante/cfdi:Conceptos/cfdi:Concepto/cfdi:Impuestos/cfdi:Traslados/cfdi:Traslado")
doc_pass2.each do |pass2|
hash_impuesto = {}
hash_impuesto[:tax] = pass2['Importe']
array_i << hash_impuesto
end
these are the results I get from the xml file:
(byebug) array
[{:importe=>"865.74"}, {:importe=>"572.80"}, {:importe=>"359.45"}, {:importe=>"408.62"}, {:importe=>"324.48"}, {:importe=>"649.64"}, {:importe=>"823.45"}, {:importe=>"545.15"}, {:importe=>"428.02"}, {:importe=>"527.21"}, {:importe=>"487.67"}, {:importe=>"331.72"}, {:importe=>"511.64"}, {:importe=>"406.67"}, {:importe=>"820.81"}, {:importe=>"1635.54"}, {:importe=>"484.14"}, {:importe=>"564.83"}, {:importe=>"1463.30"}]
(byebug) array_i
[{:importe=>"134.81"}, {:importe=>"89.20"}, {:importe=>"55.97"}, {:importe=>"63.63"}, {:importe=>"50.52"}, {:importe=>"101.18"}, {:importe=>"128.21"}, {:importe=>"84.88"}, {:importe=>"66.73"}, {:importe=>"82.10"}, {:importe=>"75.90"}, {:importe=>"51.58"}, {:importe=>"79.67"}, {:importe=>"63.33"}, {:importe=>"127.80"}, {:importe=>"254.69"}, {:importe=>"75.36"}, {:importe=>"87.92"}, {:importe=>"227.84"}]
now what I want is to sum both values(importe + impuesto) for example:
865.74 + 134.81
572.80 + 89.20
359.45 + 55.97
I am new with rails, I would appreciate your help
You can return an array with results if both arrays have the same size(I think yes), like this:
(0..array.size - 1).each_with_object([]) { |i, obj| obj << array[i][:importe].to_f + array_i[i][:importe].to_f }
result:
[1000.55, 662.0, 415.41999999999996, 472.25, 375.0, 750.8199999999999, 951.6600000000001, 630.03, 494.75, 609.3100000000001, 563.57, 383.3, 591.31, 470.0, 948.6099999999999, 1890.23, 559.5, 652.75, 1691.1399999999999]
Use zip method to combine values at corresponding index of two arrays
result = array.zip(array_i)
.map { |importe, impuesto| importe[:importe].to_f + impuesto[:importe].to_f }
Or can be simplified more for your concrete data structure
result = array.zip(array_i).map { |hashes| hashes.sum {|h| h[:importe].to_f }}
Better approach would be if you extract Concepto object with Impuesto and Importe values directly from xml, then you don't need to combine different arrays, but use nicely structured object.

First of all, you are sending the spider more time on the same site, though with different form parameters. You have therefore to use dont_filter=True in the request, otherwise Scrapy blocks duplicate calls.
Then it seems to me that the site you are scraping don't allow you to make more than one request during the same session. Try for example to go to http://fcainfoweb.nic.in/PMSver2/Reports/Report_Menu_web.aspx with your browser, compile the form, get the data and than to go back to the initial page: It's impossible. So you have to modify your spider. Here's a very rough code just to give an idea. It works for me, but please don't use it in production!

I have a list of strings, each one contains text with date like this:
"foo_6.7.2016"
"foo_5.10.2016"
"foo_6.30.2016"
"foo_6.23.2016"
"foo_6.2.2016"
"foo_5.22.2016"
I need to sort them by Date and get this:
"foo_6.30.2016"
"foo_6.23.2016"
"foo_6.7.2016"
"foo_6.2.2016"
"foo_5.22.2016"
"foo_5.10.2016"
An alternative might be:
def foos = [
"foo_6.7.2016",
"foo_5.10.2016",
"foo_6.30.2016",
"foo_6.23.2016",
"foo_6.2.2016",
"foo_5.22.2016"
]
def sorted = foos.sort(false) { Date.parse('M.d.yyyy', it - 'foo_') }.reverse()
For a quick answer that needs substantial cleanup:
def dates = [
"foo_6.7.2016"
"foo_5.10.2016"
"foo_6.30.2016"
"foo_6.23.2016"
"foo_6.2.2016"
"foo_5.22.2016"
]
def prefix = "foo_"
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("M.d.yyyy")
def sorted_dates = dates.collect{ sdf.parse(
it, new java.text.ParsePosition(prefix.length()) ) }.sort().reverse()
def newDates = sorted_dates.collect{ "${prefix} + ${sdf.format(it)}"}
println newDates
I have a ruby string array value and i want to get it as string value. I am using ruby with chef recipe. Running in windows platform. Code-
version_string = Mixlib::ShellOut.new('some.exe -version').run_command
Log.info(version.stdout.to_s)
extract_var = version_string.stdout.to_s.lines.grep(/ver/)
Log.info('version:'+ extract_var.to_s)
output is coming-
version 530
[2016-06-08T07:03:49+00:00] INFO: version ["version 530\r\n"]
I want to extract 530 string only.
long time no see since Rot :)
You can use some Chef helper methods and regular expressions to make this a little easier.
output = shell_out!('saphostexec.exe -version', cwd: 'C:\\Program Files\\hostctrl\\exe').stdout
if output =~ /kernel release\s+(\d+)/
kernel_version = $1
else
raise "unable to parse kernel version"
end
Chef::Log.info(kernel_version)
As you want val = 720 and not val = "720" you can write
val = strvar.first.to_i
#=> 720
You can return the first series of digits found as an integer from the current_kernel string with String#[regexp] :
current_kernel[/\d+/].to_i
#=> 720
Folks,
I am using REXML for a sample XML file:
<Accounts title="This is the test title">
<Account name="frenchcustomer">
<username name = "frencu"/>
<password pw = "hello34"/>
<accountdn dn = "https://frenchcu.com/"/>
<exporttest name="basic">
<exportname name = "basicexport"/>
<exportterm term = "oldschool"/>
</exporttest>
</Account>
<Account name="britishcustomer">
<username name = "britishcu"/>
<password pw = "mellow34"/>
<accountdn dn = "https://britishcu.com/"/>
<exporttest name="existingsearch">
<exportname name = "largexpo"/>
<exportterm term = "greatschool"/>
</exporttest>
</Account>
</Accounts>
I am reading the XML like this:
#data = (REXML::Document.new file).root
#dataarr = ##testdata.elements.to_a("//Account")
Now I want to get the username of the frenchcustomer, so I tried this:
#dataarr[#name=fenchcustomer].elements["username"].attributes["name"]
this fails, I do not want to use the array index, for example
#dataarr[1].elements["username"].attributes["name"]
will work, but I don't want to do that, is there something that i m missing here. I want to use the array and get the username of the french user using the Account name.
Thanks a lot.
I recommend you to use XPath.
For the first match, you can use first method, for an array, just use match.
The code above returns the username for the Account "frenchcustomer" :
REXML::XPath.first(yourREXMLDocument, "//Account[#name='frenchcustomer']/username/#name").value
If you really want to use the array created with ##testdata.elements.to_a("//Account"), you could use find method :
french_cust_elt = the_array.find { |elt| elt.attributes['name'].eql?('frenchcustomer') }
french_username = french_cust_elt.elements["username"].attributes["name"]
puts #data.elements["//Account[#name='frenchcustomer']"]
.elements["username"]
.attributes["name"]
If you want to iterate over multiple identical names:
#data.elements.each("//Account[#name='frenchcustomer']") do |fc|
puts fc.elements["username"].attributes["name"]
end
I don't know what your ##testdata are, I tried with the following testcode:
require "rexml/document"
#data = (REXML::Document.new DATA).root
#dataarr = #data.elements.to_a("//Account")
# Works
