In Webload, there is a function extractValue("start","end", source, 1) that basically just extracts any values between a specified start and end point. So for example if you have abcdefg and you want to extract cde you could do extractValue("b","f", source, 1) etc. However, the issue i am having is because webload seems to use backslashes as a marker for quotations, so for example if you had something like
ab"cde"fg you would need to use something like extractValue("b\"","\"f", source, 1) if you only wanted to extract cef.
Now my issue is I have a string like abcde\ and I want to extract only cde, I try something like
extractValue("ab","\", source, 1), however when doing this webload assumes I am not ending my string since it interprets the second quotation in "\" as part of the string.
Does anyone know how exactly I should deal with this if I want \ to be interpreted as part of a string and not as the indicator for the quotation?
Thanks
try using two backslashes like extractValue("ab","\\", source, 1), this is another example for using escape character using backslash in extractValue function
myTitle = extractValue( "<\title>", "</title>",
MyFrame.document.wlSource) backslash title is the title tag..i dont know why it is not getting displayed in the answer.

I'm honestly a novice on scilab.
I'm using print function to create .txt file with my character matrix in it.
But , when I open txt file, double quote appeared. I just want words without "".
This is how I'm using print
Compterendu(1,1)= "Medecin demandeur: "
fileresname= fullfile(RES_PATH, "compterendu.txt")
print(fileresname,Compterendu)
And, compterendu.txt was printed out like this.
Would be so grateful for any help!!
Thanks
Why do you use "print" ? After looking into the doc, yes, it is used to produce the same text as when you type the expression or the variable name on the command line. Hence it does print double quotes for strings. If you need something more basic use lower level i/o commands, like mputl.

Let's say you have a table called Employee and one of the employee names begins or includes the [$] or [#] sign within the String, like Hel$lo or like #heLLo. How can you call the value?
Is it possible to select and trim the value in a single command?
Kind regards
If you want to select the names, but with special characters $ and # removed, you can use the TRANSLATE function. Add more characters to the list if you need to.
select translate(name, 'A$#', 'A') from employee;
The function will "translate" the character 'A' to itself, '$' and '#' to nothing (simply removing them from the string), and it will leave all other characters - other than A, $ and # - unchanged. It may seem odd that you need the 'A' in this whole business; and you really don't need 'A' specifically, but you do need some character that you want to keep. The reason for that is Oracle's idiotic handling of null; don't worry about the reason, just remember the technique.
You may need to remove characters but you don't know in advance what they will be. That can be done too, but you need to be careful not to remove legitimate characters, like the dot (A. C. Green), dash (John Connor-Smith), apostrophe (Betty O'Rourke) etc. You can then do it either with regular expressions (easy to write, but not the most efficient) or with TRANSLATE as above (it looks uglier, but it will run faster). Something like this:
select regexp_replace(name, [^[:alpha:].'-]) from employee
This will replace any character that is not "alpha" (letters) or one of the characters specifically enumerated (dot, apostrophe, dash) with nothing, effectively removing them. Note that dash has a special meaning in character classes, so it must be the last one in the enumeration.
If you need to make the changes in the table itself, you can use an update statement, using TRANSLATE or REGEXP_REPLACE as shown above.
How to extract data without quotes in iMacros? The following code can remove comma, but still give me quotes sign.
SET !VAR6 EVAL("var s='{{!EXTRACT}}'; s.replace(',', '');")
I am using FF broser. Thanks in advance.
You want to remove ' from your text together with the ,? Your code keeps the quotes, because you don't do anything to replace them. You can use
SET !VAR6 EVAL("var s='{{!EXTRACT}}'; s.replace(/[,']/g, '');")
to replace every occurence of either character. Read up on regular expressions and on replace to tweak this if it's not precisely what you want.
I am creating a custom code highlight for notepad++. What I want to do is the following:
some fieldnames are writen in the code with a ' in front of their name, for exampe
if 'variable = "test" then ...
I would like to highlight these words, but notepad++ does not seem to allow a delimiter starting with ' and ending with a space, not does it allow space as an escape character. Also, using ' as a keyword and enabling prefix mode has no effect. Anyone has a suggestion? Should I use another expression to let notepad recognise the space/' ?
Thanks in advance!
If you only need to highlight a single word, you can use a keyword in prefix mode. However when using single or double quotes in a keyword, they need to be escaped with a backslash. So your keyword would be:
\'
This may not be possible in notepad++. I can get the behavior you want using a character other than a single quote, like a back-tic, but it doesn't seem to work with single or double quotes. I suspect those characters are treated special within the syntax highlighter.
In my Ruby app, I've used the following method and regular expression to remove all HTML tags from a string:
str.gsub(/<\/?[^>]*>/,"")
This regular expression did just about all I was expecting it to, except it caused all quotation marks to be transformed into “
and all single quotes to be changed to ”
.
What's the obvious thing I'm missing to convert the messy codes back into their proper characters?
Edit: The problem occurs with or without the Regular Expression, so it's clear my problem has nothing to do with it. My question now is how to deal with this formatting error and correct it. Thanks!
Use CGI::unescapeHTML after you perform your regular expression substitution:
CGI::unescapeHTML(str.gsub(/<\/?[^>]*>/,""))
See http://www.ruby-doc.org/core/classes/CGI.html#M000547
In the above code snippet, gsub removes all HTML tags. Then, unescapeHTML() reverts all HTML entities (such as <, “) to their actual characters (<, quotes, etc.)
With respect to another post on this page, note that you will never ever be passed HTML such as
<tag attribute="<value>">2 + 3 < 6</tag>
(which is invalid HTML); what you may receive is, instead:
<tag attribute="<value>">2 + 3 < 6</tag>
The call to gsub will transform the above to:
2 + 3 < 6
And unescapeHTML will finish the job:
2 + 3 < 6
You're going to run into more trouble when you see something like:
<doohickey name="<foobar>">
You'll want to apply something like:
gsub(/<[^<>]*>/, "")
...for as long as the pattern matches.
This regular expression did just about
all I was expecting it to, except it
caused all quotation marks to be
transformed into “ and all
single quotes to be changed to ”
.
This doesn't sound as if the RegExp would be doing this. Are you sure it's different before?
See this question here for information about the problem, it has got an excellent answer:
Get non UTF-8 form fields as UTF-8 in php.
I've run into a similar problem with character changes, this happened when my code ran through another module that enforced UTF-8 encoding and then when it came back, I had a different file (slurped array of lines) on my hands.
You could use a multi-pass system to get the results you are looking for.
After running your regular expression, run an expression to convert &8220; to quotes and another to convert &8221; to single quotes.
