由 ≯℡__Kan透↙ 提交于 2019-12-11 09:05:19
问题 What I'm trying to do is take a block of html, strip out all the html tags, and put each line of text into a PHP array. I'm just trying it with one block to test (hence the WHERE ID = '2409' in my mysql query. The HTML portion for ID 2409 looks like this: <table class="description-table"> <tbody> <tr><td>Saepe Encomia 2.aD NEC Mirum Populo Soluni Iis 8679-1370 Status Error Sed 9.9</td></tr> <tr><td>Description</td></tr> <tr><td></td> <td><br> <br><p></p><p></p> <strong><br></strong> <strong>

C# maskedTextbox, how to disable whitespaces?

由 拜拜、爱过 提交于 2019-12-11 05:21:30
问题 I cant figure out how to disable whitespaces, I tried multiple things, and yes my mask is 00000000000 but still it allows whitespaces. Anyone know a fix? Not much code to show, only: Should only allow numbers to be entered, not whitespaces too :/ 回答1: Add the KeyDown Event to your textbox and then add the following Code in the created method: private void textBox_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Space) { e.Handled = true; e.SuppressKeyPress = true; return; } } 来源

How to remove   from the end of spans with a given class?

由 不问归期 提交于 2019-12-10 03:59:40
问题 I need to remove the   after the value of given spans. The HTML looks like this: <span class="number">0.15 </span> The   is coming from the server (CMS). Is there any way to remove the   by using CSS rules? 回答1: If this value is provided by your CMS, it's posible you can modify the value with php via str_replace(' ', '', $yourVar) before echo it in your span. If you can't access with this, you can also use jQuery to do this... Just like Muhammad Ali said : var str = $('.number').html(); str

In Haskell, how do you trim whitespace from the beginning and end of a string?

问题 How do you trim whitespace from the start and end of a string? trim " abc " => "abc" Edit: Ok, let me be a little clearer. I did not understand that string literals were treated so differently from Strings. I would like to do this: import qualified Data.Text as T let s :: String = " abc " in T.strip s Is this possible in Haskell? I am using -XOverloadedStrings but that appears only to work for literals. 回答1: If you have serious text processing needs then use the text package from hackage: >

How to remove white spaces in JSF output?

由 余生长醉 提交于 2019-12-07 07:55:04
问题 Is it possible to configure JSF 2.0 to remove unnecessary white spaces between XHTML tags? 回答1: No. Facelets cannot distinguish unnecessary whitespace from necessary whitespace. For that it would need to determine individual HTML tags, parse CSS and JS files for any evidence that it is really unnecessary. In case of the HTML <pre> and <textarea> tags, the CSS white-space:pre property and JS element.style.whiteSpace='pre' code, the whitespace is namely significant. It's simply too expensive

Halve the number of whitespace at the begining of each line in Vim

由 旧城冷巷雨未停 提交于 2019-12-05 15:51:09
Can someone tell me how to do the opposite of this mapping in Vim: nnoremap <leader>iw :let _s=@/<Bar>:let _s2=line(".")<Bar>:%s/^\s*/&&/ge<Bar>:let @/=_s<Bar>:nohl<Bar>exe ':'._s2<CR> As clarification, this mapping doubles ( && part) the number of whitespace at the beginning of each line. Only whitespaces before first regular character are affected. Current search string is kept (variable _s ). Position is restored after this transformation (variable _s2 ) So basically I'm searching for a mapping that will undo this one if they are executed one after another. I'm having trouble in figuring

Ignoring whitespace (in certain parts) in Antlr4

由 不打扰是莪最后的温柔 提交于 2019-12-04 20:02:10
I am not so familiar with antlr. I am using version 4 and I have a grammar where whitespace is not important in some parts (but it might be in others, or rather its luck). So say we have the following grammar grammar Foo; program : A* ; A : ID '@' ID '(' IDList ')' ';' ; ID : [a-zA-Z]+ ; IDList : ID (',' IDList)* ; WS : [ \t\r\n]+ -> skip ; and a test input foo@bar(X,Y); foo@baz ( z,Z) ; The first line is parsed correctly whereas the second one is not. I don't want to polute my rules with the places where whitespace is not relevant, since my actual grammar is more complicated than the toy

How to remove multiple spaces in Strings with Swift 2

由 佐手、 提交于 2019-12-04 16:28:11

Thnx! 回答1: In Swift 2 , join has become joinWithSeparator and you
