View 3 RepliesJavascript - How To Check Whether A Certain Text Box Exists In A Page
Feb 9, 2010Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.
Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.
How I can I do that in javascript?
C# - Check Text For HTML With Regular Expression?
Nov 23, 2010This is slightly different to most questions regarding HTML tags in strings - I want to add HTML!
I'm using a WYSIWYG editor which produces some eratic results. What im looking to do is to check the string it produces and check whether there are any sentences that aren't wrapped in a <p></p> tag. Typical strings could be:
Example 1
<p>Hello, this is string 1</p>
But string two doesnt appear to be in a <p> tag.
Example 2
None of this text is in <p> tags.
Example 3
Single line of text, again not in a <p> tag.
Could this be done using a regular expression?
C# - XElement.ToString() Causes System.OutOfMemoryException?
Nov 25, 2010I have an XElement object that contains about 120MB of data. The XML consists of approx 6000 elements of about 20kb each.
I am trying to call XElement.ToString() as I need to return the OuterXml in a webservice.
I am getting a System.OutOfMemoryException.
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown:

I have the same data in an XmlDocument and can call XmlDocument.OuterXml without a problem. I can also call XElement.Save() to save the XML to a file without a problem.
