In Flex I want to create a Text file and it is working, but the problem is all inputs are written in one line;
here the cods
addText.text="[ \r\n"
addText.text=addText.text+"] \r\n";
fileRef.save(addText.text, "data.txt");
the current result is like below;
[]
how can I make it like this;
[
]
i would start trying
addTextxt.text = "[ \n ]";
it normally works in all cases...
good luck ( :

I've been trying to extract some text for a while now, and while everything works fine, there is something I can't manage to get.
Take this website : https://duproprio.com/fr/montreal/pierrefonds-roxboro/condo-a-vendre/hab-305-5221-rue-riviera-854000
I want to get the texts from the class=listing-main-characteristics__number nodes (below the picture, the box with "2 chambres 1 salle de bain Aire habitable (s-sol exclu) 1,030 pi2 (95,69m2)", there are 3 elements with that class in the page ( "2", "1" and "1,030 pi² (95,69 m²)"). I've tried a bunch of options in XPath and CSS, but none has worked, some gave back strange answers.
For example, with :
response.xpath('//span[#class="listing-main-characteristics__number"]').getall()
I get :
['<span class="listing-main-characteristics\_\_number">\n 2\n </span>', '<span class="listing-main-characteristics\_\_number">\n 1\n </span>']
For example, something else that works just fine on the same webpage :
response.xpath('//div[#property="description"]/p/text()').getall()
If I get all the spans with this query :
response.css('span::text').getall()
I can find my texts mentioned in the beginning in the. But from this :
response.css('span[class=listing-main-characteristics__number]::text').getall()
I only get this
['\n 2\n ', '\n 1\n ']
Could someone clue me in with what kind of selection I would need? Thank you so much!
Here is the xpath that you have to use.
//div[#data-label='#description']//div[#class='listing-main-characteristics__label']|//div[#data-label='#description']//div[#class='listing-main-characteristics__item-dimensions']/span[2]
you might have to use the above xpath. (Add /text() is you want the associated text.)
response.xpath("//div[#data-label='#description']//div[#class='listing-main-characteristics__label']|//div[#data-label='#description']//div[#class='listing-main-characteristics__item-dimensions']/span[2]").getall()
Below is the python sample code
url = "https://duproprio.com/fr/montreal/pierrefonds-roxboro/condo-a-vendre/hab-305-5221-rue-riviera-854000#description"
driver.get(url)
# get the output elements then we will get the text from them
outputs = driver.find_elements_by_xpath("//div[#data-label='#description']//div[#class='listing-main-characteristics__label']|//div[#data-label='#description']//div[#class='listing-main-characteristics__item-dimensions']/span[2]")
for output in outputs:
# replace the new line character with space and trim the text
print(output.text.replace("\n", ' ').strip())
Output:
2 chambres
1 salle de bain
1,030 pi² (95,69 m²)
Screenshot:
Everytime I add CharW(34) to a string it adds two "" symbols
Example:
text = "Hello," + Char(34) + "World" + Char(34)
Result of text
"Hello,""World"""
How can I just add one " symbol?
e.g Ideal result would be:
"Hello,"World""
I have also tried:
text = "Hello,""World"""
But I still get the double " Symbols
Furthermore. Adding a CharW(39), which is a ' symbol only produces one?
e.g
text = "Hello," + Char(39) + "World" + Char(39)
Result
"Hello,'World'"
Why is this only behaving abnormally for double quotes? and how can I add just ONE rather than two?
Assuming you meant the old Chr function rather than Char (which is a type).It does not add two quotation mark characters. It only adds one. If you output the string to the screen or a file, you would see that it only adds one. The Visual Studio debugger, however, displays the VB-string-literal representation of the value rather than the raw string value itself. Since the way to escape a double-quote character in a string is to put two in a row, that's the way it displays it. For instance, your code:
text = "Hello," + Chr(34) + "World" + Chr(34)
Can also be written more simply as:
text = "Hello,""World"""
So, the debugger is just displaying it in that VB syntax, just as in C#, the debugger would display the value as "Hello, \"World\"".
The text doesn't really have double quotes in it. The debugger is quoting the text so that it appears as it would in your source code. If you were to do this same thing in C#, embedded new lines are displayed using it's source code formatting.
Instead of using the debugger's output, you can add a statement in your source to display the value in the debug window.
Diagnostics.Debug.WriteLine(text)
This should only show the single set of quotes.
Well it's Very eazy
just use this : ControlChars.Quote
"Hello, " & ControlChars.Quote & "World" & ControlChars.Quote
Using DocX I need to do something like this:
A long
text description.
Except I need the "1." to be a paragraph and the "A long text description" to be a paragraph. I cannot use a list for this.
late answer, but use a 2 column table with no visible borders
some code i hacked out of my current thing. this makes a table and populates the cells with the contents of my cells,
you'd just need to make a table, with 2 columns. and then iterate build a row with with cell[0] for the numeral, and cell[1] for the sentence
doc.InsertParagraph("Table Title: " + (component).SubTitle, false, SubtitleStyle);
var table = doc.AddTable(component.ColumnCount, component.RowCount);
int rowcount = 0;
foreach (DataCell datacell in component.TableData)
{
table.Rows[rowcount].Cells[0].Paragraphs.First().Append(rowcount+1);
table.Rows[rowcount].Cells[1].Paragraphs.First().Append(datacell.CellValue);
rowcount++;
}
doc.InsertTable(table);
Ok, here is the small portion of code to demonstrate:
CString txt = _T("Hello World");
CString txt2 = txt;
txt2.TrimRight('W');
AfxMessageBox(txt2);
The output is "Hello World".
What am I not getting right ?
The call txt2.TrimRight('W'); removes all characters 'W' from the right side of the string. Since "Hello World" does not end in 'W' nothing is trimmed at all.
I would like to come up with a Vim substitution command to turn multi-line CSS rules, like this one:
#main {
padding: 0;
margin: 10px auto;
}
into compacted single-line rules, like so:
#main {padding:0;margin:10px auto;}
I have a ton of CSS rules that are taking up too many lines, and I cannot figure out the :%s/ commands to use.
Here's a one-liner:
:%s/{\_.\{-}}/\=substitute(submatch(0), '\n', '', 'g')/
\_. matches any character, including a newline, and \{-} is the non-greedy version of *, so {\_.\{-}} matches everything between a matching pair of curly braces, inclusive.
The \= allows you to substitute the result of a vim expression, which we here use to strip out all the newlines '\n' from the matched text (in submatch(0)) using the substitute() function.
The inverse (converting the one-line version to multi-line) can also be done as a one liner:
:%s/{\_.\{-}}/\=substitute(submatch(0), '[{;]', '\0\r', 'g')/
If you are at the beginning or end of the rule, V%J will join it into a single line:
Go to the opening (or closing) brace
Hit V to enter visual mode
Hit % to match the other brace, selecting the whole rule
Hit J to join the lines
Try something like this:
:%s/{\n/{/g
:%s/;\n/;/g
:%s/{\s+/{/g
:%s/;\s+/;/g
This removes the newlines after opening braces and semicolons ('{' and ';') and then removes the extra whitespace between the concatenated lines.
If you want to change the file, go for rampion's solution.
If you don't want (or can't) change the file, you can play with a custom folding as it permits to choose what and how to display the folded text. For instance:
" {rtp}/fold/css-fold.vim
" [-- local settings --] {{{1
setlocal foldexpr=CssFold(v:lnum)
setlocal foldtext=CssFoldText()
let b:width1 = 20
let b:width2 = 15
nnoremap <buffer> + :let b:width2+=1<cr><c-l>
nnoremap <buffer> - :let b:width2-=1<cr><c-l>
" [-- global definitions --] {{{1
if exists('*CssFold')
setlocal foldmethod=expr
" finish
endif
function! CssFold(lnum)
let cline = getline(a:lnum)
if cline =~ '{\s*$'
return 'a1'
elseif cline =~ '}\s*$'
return 's1'
else
return '='
endif
endfunction
function! s:Complete(txt, width)
let length = strlen(a:txt)
if length > a:width
return a:txt
endif
return a:txt . repeat(' ', a:width - length)
endfunction
function! CssFoldText()
let lnum = v:foldstart
let txt = s:Complete(getline(lnum), b:width1)
let lnum += 1
while lnum < v:foldend
let add = s:Complete(substitute(getline(lnum), '^\s*\(\S\+\)\s*:\s*\(.\{-}\)\s*;\s*$', '\1: \2;', ''), b:width2)
if add !~ '^\s*$'
let txt .= ' ' . add
endif
let lnum += 1
endwhile
return txt. '}'
endfunction
I leave the sorting of the fields as exercise. Hint: get all the lines between v:foldstart+1 and v:voldend in a List, sort the list, build the string, and that's all.
I won’t answer the question directly, but instead I suggest you to reconsider your needs. I think that your “bad” example is in fact the better one. It is more readable, easier to modify and reason about. Good indentation is very important not only when it comes to programming languages, but also in CSS and HTML.
You mention that CSS rules are “taking up too many lines”. If you are worried about file size, you should consider using CSS and JS minifiers like YUI Compressor instead of making the code less readable.
A convenient way of doing this transformation is to run the following
short command:
:g/{/,/}/j
Go to the first line of the file, and use the command gqG to run the whole file through the formatter. Assuming runs of nonempty lines should be collapsed in the whole file.
