• Regex if-else expression

  - by craig

  I'm trying to extract the # of minutes from a text field using Oracle's REGEXP_SUBSTR() function. Data: Treatment of PC7, PT1 on left. 15 min. 15 minutes. 15 minutes 15 mins. 15 mins 15 min. 15 min 15min 15 In each case, I'm hoping to extract the '15' part of the string. Attempts: \d+ gets all of the numeric values, including the '7' and '1', which is undesirable. (\d)+(?=\ ?min) get the '15' from all rows except the last. (?((\d)+(?=\ ?min))((\d)+(?=\ ?min))|\d+), an if-else statement, doesnt' match anything. What is wrong with my if-else statement?

• Remove all html tags from attributes in rails

  - by Hock

  I have a Project model and it has some text attributes, one is summary. I have some projects that have html tags in the summary and I want to convert that to plain text. I have this method that has a regex that will remove all html tags. def strip_html_comments_on_data self.attributes.each{|key,value| value.to_s.gsub!(/(<[^>]+>|&nbsp;|\r|\n)/,"")} end I also have a before_save filter before_save :strip_html_comments_on_data The problem is that the html tags are still there after saving the project. What am I missing? And, is there a really easy way to have that method called in all the models? Thanks, Nicolás Hock Isaza

• Split a html string in N parts

  - by Matt Brailsford

  Hi Guys, Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words. I was thinking of just splitting the html and using the HtmlAgilityPack to try and fix the broken tags. Though I'm not sure how to find the split point, as Ideally it should be based purley on the text rather than the html aswell. Anybody got any ideas on how to go about this? Many thanks Matt

• Regular Expression to return the contents of a HTML tag received as a string of text

  - by Nathan Hernandez

  I have a string in my code that I receive that contains some html tags. It is not part of the HTML page being displayed so I cannot grab the html tag contents using the DOM (i.e. document.getElementById('tag id').firstChild.data); So, for example within the string of text would appear a tag like this: 12 My question is how would I use a regular expression to access the '12' numeric digit in this example? This quantity could be any number of digits (i.e. it is not always a double digit). I have tried some regular expressions, but always end up getting the full span tag returned along with the contents. I only want the '12' in the example above, not the surrounding tag. The id of the tags will always be 'myQty' in the string of text I receive. Thanks in advance for any help!

• Extract IP address from an html string (python)

  - by GoJian

  My Friends, I really want to extract a simple IP address from a string (actually an one-line html) using Python. But it turns out that 2 hours passed I still couldn't come up with a good solution. >>> s = "<html><head><title>Current IP Check</title></head><body>Current IP Address: 165.91.15.131</body></html>" -- '165.91.15.131' is what I want! I tried using regular expression, but so far I can only get to the first number. >>> import re >>> ip = re.findall( r'([0-9]+)(?:\.[0-9]+){3}', s ) >>> ip ['165'] In fact, I don't feel I have a firm grasp on reg-expression and the above code was found and modified from elsewhere on the web.

• Centring an HTML element relative to its parent when its width is greater than its parent. [closed]

  - by casr

  I mocked up my intended outcome. So the blue element is the main content of the website and the yellow element represents something like a diagram or an image that has a greater width than the blue element. Ideally, I would like a purely CSS solution that is able to deal with various sizes of images. I have tried various things but have failed so far. I hope you can help! Here’s some example markup to set you on your way. <!DOCTYPE HTML> <html> <head> <title>Example</title> <style> #el1 { display: block; margin: 0 auto; width: 30em; background-color: #8cabde } #el2 { /* works when the width is less than the parent */ display: block; margin: 0 auto; } </style> </head> <body> <article id=el1> <p>Some content above.</p> <img id=el2 src=http://i.imgur.com/JFfGG.gif title=spaceball width=600 height=400> <p>Some content below.</p> </article> </body> </html>

• Why is Html.DropDownList() producing <select name="original_name.name"> instead of just <select name

  - by DanM

  I have an editor template whose job is to take a SelectList as its model and build a select element in html using the Html.DropDownList() helper extension. I'm trying to assign the name attribute for the select based on a ModelMetadata property. (Reason: on post-back, I need to bind to an object that has a different property name for this item than the ViewModel used to populate the form.) The problem I'm running into is that DropDownList() is appending the name I'm providing instead of replacing it, so I end up with names like categories.category instead of category. Here is some code for you to look at... SelectList.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Mvc.SelectList>" %> <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model) %> Resulting HTML <select id="SkillLevels_SkillLevel" name="SkillLevels.SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Expected HTML <select id="SkillLevels_SkillLevel" name="SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Also tried <%= Html.Encode((string)ViewData.ModelMetadata.AdditionalValues["PropertyName"])%> ...which resulted in "SkillLevel" (not "SkillLevels.SkillLevel"), proving that the data stored in metadata is correct. and <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model, new { name = (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"] }) %> ...which still resulted in <select name=SkillLevels.Skilllevel>. Questions What's going on here? Why does it append the name instead of just using it? Can you suggest a good workaround? Update: I ended up writing a helper extension that literally does a find/replace on the html text: public static MvcHtmlString BindableDropDownListForModel(this HtmlHelper helper) { var propertyName = (string)helper.ViewData.ModelMetadata.AdditionalValues["PropertyName"]; var compositeName = helper.ViewData.ModelMetadata.PropertyName + "." + propertyName; var rawHtml = helper.DropDownList(propertyName, (SelectList)helper.ViewData.Model); var bindableHtml = rawHtml.ToString().Replace(compositeName, propertyName); return MvcHtmlString.Create(bindableHtml); }

• Mark text in HTML

  - by Alon

  Hi I have some plain text and html. I need to create a PHP method that will return the same html, but with <span class="marked"> before any instances of the text and </span> after it. Note, that it should support tags in the html (for example if the text is blabla so it should mark when it's bla<b>bla</b> or <a href="http://abc.com">bla</a>bla. It should be incase sensitive and support long text (with multilines etc) either. For example, if I call this function with the text "my name is josh" and the following html: <html> <head> <title>My Name Is Josh!!!</title> </head> <body> <h1>my name is <b>josh</b></h1> <div> <a href="http://www.names.com">my name</a> is josh </div> <u>my</u> <i>name</i> <b>is</b> <span style="font-family: Tahoma;">Josh</span>. </body> </html> ... it should return: <html> <head> <title><span class="marked">My Name Is Josh</span>!!!</title> </head> <body> <h1><span class="marked">my name is <b>josh</b></span></h1> <div> <span class="marked"><a href="http://www.names.com">my name</a> is josh</span> </div> <span class="marked"><u>my</u> <i>name</i> <b>is</b> <span style="font-family: Tahoma;">Josh</span></span>. </body> </html> Thanks.

• outputting html in runtime in asp.net

  - by madness800

  Hi all, I'm building a website at the moment, I've some html fragment that is being stored into the database, I've been reading around that inserting HTML at runtime poses security risks by using the InnerHTML property of any html tag with runat server on it. So, my question is there any alternative way to safely display the html code and won't pose security risks and is it best to assume any textboxes on any given page is dangerous and process the text in the textboxes with Server.HtmlEncode before I store it to database? Cheers
