text = "Donc", "j'obtiens", "<i>aᵢ₁([Alpha]₁ - [Beta]₁) + aᵢ₂([Alpha]₂ - 
[Beta]₂) + ... + aₙ₁([Alpha]ₙ - [Beta]ₙ) = bᵢ - bᵢ = 0.</i>", 
"<i>aᵢ₁([Alpha]₁ - [Beta]₁) + aᵢ₂([Alpha]₂ - [Beta]₂) + ... + 
aₙ₁([Alpha]ₙ - [Beta]ₙ) = bᵢ - bᵢ = 0.</i>", "Donc en particulier", 
"ça veut dire que si je multiplie par <i>c</i>", "pour tout nombre réel 
<i>c</i>"


Now my question is:



  1. How can I get the position of in the list of every object that starts with <i>?


  2. How can I replace the <i> at the start of that object and the </i> at the end of that object by another string ?


By "object" I really mean a list object: for instance, I don't want the <i> and </i> to be replaced in "ça veut dire que si je multiplie par <i>c</i>", since this object of the list does not start with an <i>.



EDIT: To clear any confusion, here is how the text could look like afterwards:



"Donc", "j'obtiens", "REPLACE([Alpha]₁ - [Beta]₁) + aᵢ₂([Alpha]₂ - 
 [Beta]₂) + ... + aₙ₁([Alpha]ₙ - [Beta]ₙ) = bᵢ - bᵢ = 0.REPLACE", 
 "REPLACEaᵢ₁([Alpha]₁ - [Beta]₁) + aᵢ₂([Alpha]₂ - [Beta]₂) + ... + 
 aₙ₁([Alpha]ₙ - [Beta]ₙ) = bᵢ - bᵢ = 0.REPLACE", "Donc en particulier", 
 "ça veut dire que si je multiplie par <i>c</i>", "pour tout nombre réel 
 <i>c</i>"

  • Could try something like Position[text, s_String /; StringMatchQ[s, "<i>*</i>"]], but that won't catch the last two items with italics tags since they don't actually "start with <i>", as the criterion you mentioned.

  • @J.M.iscomputer-less That's actually perfect ! Maybe I was not clear enough, but I don't want to catch "<i>" where the sentence does not start with "<i>". Can you post it as an answer ? Then I can accept it, if you also know how to replace the "<i>" and "</i>" in the found sentences.

  • That's what I was asking you about earlier @james. So, what you want is a derived string and not an independent string. That's because replacing <i>stuff</i> with stuff and replacing <i>stuff</i> with something needs different approaches.

  • This replaces everything in between "<i>" and "<i/>". Please have a look at my example in the question.

  • That's what I was asking you about earlier @james. So, what you want is a derived string and not an independent string. That's because replacing <i>stuff</i> with stuff and replacing <i>stuff</i> with something needs different approaches.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
