ruby - why can't i wrap <span> around the rfollowing nokogiri xpath? -

- 

  डॉक्टर = नोकोगीरी :: HTML (खुले (url))। Xpath ("// *") .xpath ("/ * [Br] / पाठ () [स्ट्रिंग-लम्बाई (सामान्य-स्थान ())! = 0]"। Wrap ("& lt; span & gt; & lt; / span & gt;") डॉक्टर कहते हैं

यह अभी पाठ लौटाता है ... मैं अब पूर्ण एचटीएमएल स्रोत की उम्मीद कर रहा था जो अब निर्दिष्ट एक्सपेथ तत्वों के चारों ओर लपेटता है।

कोशिश करें 

  doc = Nokogiri :: HTML (खुला (url))। Xpath (" // * ") .xpath (" // * [ Br] और पाठ () [स्ट्रिंग-लम्बाई (सामान्य-स्थान ())! = 0]] ")। लपेटें (" & lt; span & gt; & lt; / span & gt; ") डॉक

आपका XPath क्या करता है, वह गैर रिक्त पाठ नोड्स को फैलता है उनकी परिभाषा के अनुसार कोई भी मार्कअप नहीं होता है

इसके विपरीत, मेरे XPath में कम से कम एक & lt; br & gt; और कम से कम एक गैर-खाली पाठ नोड वाले कोई भी नोड प्राप्त होता है।

Lists in scheme -

I am trying to write a function in the plan that takes every item list and class in the list, then returns the list As is (list xyz) . However, I'm not sure how to write a code that would do this. So far, I have (defined (category = list list) (cond [(empty? List) false) [and (list (SQL) (first A-list)) (Square-list) (The rest is a list)))]) but it returns to the list (cons y (cons z empty)) What can I do to return it to the list only in (list xyz) ? Thanks! You're almost there - make sure you type cons and List (The text book explains this section 13. You can find copies online). Conflict The first element for the 'rest' part and (usually) one (potentially empty) list as an example, (Opposition 1 blank) Number 1 as its first element and the empty list is in the form of 'rest' (Opposition 1 (Opposition 2 Empty)) No. 1 before Element, and (Opposition 2 empty) is in the form of 'rest'. List is just a simple shorth...

List View in C# -

I have a ListView in my C # and I want to select an item based on the number I give . Is it possible? Example: If my list adds, multiplied and divides as elements in the list, so if I give 2, then it has to be multiplied. All this should be programmatically If this is ListItem value 2 - I just had to go with it: _listView.SelectedValue = "2"; Or maybe more correct: _listView.SelectedValue = _input.ToString ();
