quote

问题 I got an " & # 39; " in my XML file. (it is the char code for the quot in HTML) EX : < desc > blabla bla & # 39 ; bla bla la. < / desc> When i parse it with String tmp = itemOfEvent.getFirstChild().getNodeValue() it cut my text juste before the quot. I got a crash with URL.encode(tmp, "UTF-8") Better idea ? 回答1: You say that the text is HTML encoded so try this: String fixedTmp = Html.fromHtml(tmp).toString(); 回答2: The best solution i've found was to replace bad char xmlString = xmlString

问题 I'm having some trouble with the sed command : I'd like to replace in a string, a single quote by two single quote Here's my string : 04CA07807800106109XE00187200000081960 NI 0780643442 178'0700 I used this sed command to replace the single quote : line=`echo $line | sed "s/'/''/g"` The result is 04CA07807800106109XE00187200000081960 NI 0780643442 178''0700 As you can see, the single quote is properly replaced by two single quotes. But I lost all the spaces between each character of my string

问题 When ever I try to execute a command to the shell via php's exec/passthru/system functions it seems to remove quotes from the command. $str_file = '1323988284_700.csv'; exec("/usr/bin/lftp -e 'set ftp:passive-mode true; set ftp:ssl-protect-data yes; put /web/files/{$str_file}; bye;' -u user,pass ftp://ftp.site.com/uploaddir/"); Here is the output from checking the process ps faxxx | grep lftp 4486 ?

问题 In question Using AND with the apply function in Scheme , I proposed an solution to apply "and" onto a list of atoms (i.e. s-exp which is neither null, nor pair.) in PLT-Scheme 372. Welcome to DrScheme, version 372 [3m]. Language: Textual (MzScheme, includes R5RS). > (eval (cons 'and (list ''#f ''#f ''#t))) #f > (eval (cons 'and (list ''a ''b ''c))) c But right after that I realized that: it's not easy to generate (quote (quote var)) or ''var dynamically. To be specific, the following code

问题 I've been writing up a micro-mini-lisp based on the encoding in minilisp, the McCarthy paper (as emended by the Roots of Lisp), and using a (possibly objectionable) style based on the J Incunabulum. And using the PP_NARG macro from here. I was also motivated by my previous project, a codegolf'ed lambda calculus interpreter which I later discovered to be eerily similar to the 1999 ioccc Lisp interpreter, particularly in the use of cursors rather than pointers to refer to memory addresses. It

问题 I'm writing a dungeon crawler game in CL, and I'm having trouble with the case form. Two things: Common Lisp complains Duplicate keyform QUOTE in CASE statement (make-instance 'cl-rogue:tile tile-type 'wall) should print as "#", but the object prints as " " no matter which tile-type I use. The code: (in-package :cl-user) (defpackage :cl-rogue (:use :common-lisp) (:export :*rows* :*cols* :*levels* :tile :tile-type :tile-contents :tile-hidden :tile-locked :tile-closed :main)) (in-package :cl

问题 I have a SSIS package importing data from a .csv file. This file has doulbe quotes ( " ) qualifiers for each entry in it but also in between. I also added commas ( , ) as a column delimiter. I can't give you the original data I'm working with but here is an example how my data is passed in Flat File Source: "ID-1","A "B"", C, D, E","Today" "ID-2","A, B, C, D, E,F","Yesterday" "ID-3","A and nothing else","Today" As you can see the second column can contain quotes (and commas) which smashes my

问题 I had never really thought about whether a symbol could be a number in Lisp, so I played around with it today: > '1 1 > (+ '1 '1) 2 > (+ '1 1) 2 > (define a '1) > (+ a 1) 2 The above code is scheme, but it seems to be roughly the same in Common Lisp and Clojure as well. Is there any difference between 1 and quoted 1? 回答1: Well, they are in fact very different. '1 is however precisely the same as (quote 1) . (car ''x) evaluates to the symbol 'quote'. 1 is an S-expression, it's the external

问题 I'm trying to escape the quotes (and apostrofes and escape char) in a text string in javascript: var text = 'Escape " and \' and /.'; var rx = new RegExp('/([\'"])/g'); console.log(text, ' ==> ', text.replace(rx,'//\1'));​​​​​ What I expect to be output is Escape /" and /' and //. , but instead I get Escape " and ' and /. . I just can't seem to get this working and don't know what's wrong. Here's a JSFiddle: http://jsfiddle.net/hvtgf/ 回答1: Escaping means using backslash \ but not slash / .
