Working on one of the tasks i am using jsstringformat function to handle json data if some special characters are used, but that does not seems to handle all issues.
My JSON still breaks.
I am using like this :
"<a href='edit.cfm?id=#jsStringFormat(qFiltered.randomnumber)#' style='color:##066D99'>#trim(jsStringFormat(qFiltered[thisColumn][qFiltered.currentRow]))#</a>"
I am lost here what else i can use as any part of regex or rereplace that it should not break
Thanks
You're doing multiple things here.
You're putting the string into a URL: use UrlEncodedFormat.
You're also putting it in an HTML tag: use HtmlEditFormat.
The whole thing is going into a JavaScript variable, so I would use JSStringFormat to wrap the whole thing.
Try building your string before assigning it.
<cfsavecontent variable="htmlLink"><cfoutput>
#HtmlEditFormat(Trim(qFiltered[thisColumn][qFiltered.currentRow]))#
</cfoutput></cfsavecontent>
myJsVar = "#JsStringFormat(Trim(htmlLink))#";

Whats the best way to remove a query string (the question mark variables) from a image url.
Say I got a good image such as
http://i.ebayimg.com/00/s/MTYwMFgxNjAw/z/zoMAAOSwMpZUniWv/$_12.JPG?set_id=880000500F
But I can't really save it properly without adding a bunch of useless checking code because of the query string crap after it.
I just need
http://i.ebayimg.com/00/s/MTYwMFgxNjAw/z/zoMAAOSwMpZUniWv/$_12.JPG
Looking for the proper regular expression that handles this so I could replace it with blank.
It might be simple enough not to worry about regex.
This would work:
Dim cleaned = url.Substring(0, url.IndexOf("?"c))
Hi I am pretty new to regex I can do some basic functions but having trouble with this. I need to change the link in the rss feed.
I have a url like this:
http://mysite.test/Search/PropDetail.aspx?id=38464&id=38464&listingid=129-2-6430678&searchID=250554873&ResultsType=SearchResult
and want to change it to updated site:
http://mysite.test/PropertyDetail/?id=38464&id=38464&listingid=129-2-6430678&searchID=250554873&ResultsType=SearchResult
Where only thing changed is from /Search/PropDetail.aspx
to /PropertyDetail/
I don't have access to the orginal rss feed or I would change it there so I have to use pipes. Please help, Thanks!
Use the regex control.
In it, specify the DOM address of the node containing your link (prefixed by "item.") within the "In" field. For the "replace" field type
(.*)//Search//PropDetail/.aspx
and in the "with" field type use:
$1//PropertyDetail//.*
I've 'escaped' the '/' character in the with field. However, I'm not sure you need to do this except before the '.*' Some trial and error may be needed.
Hopefully this will achieve the result you want.
I am working on IDML files which are used by InDesign. I am facing a problem in inserting a special instruction. I need to embed RightIndentTab with IDML file. The unicode for the same is U+0008. When I try to add that it throws error as this unicode is not supported in XML specs.
I looked more into it and IDML has a special Processing Instruction which can be inserted it looks like now the problem is when I add this it introduces a line break before the RightIndent symbol. On debugging I found that the content element looks like
<Content>
<?ACE 8?>9731396</Content>
It is an XElement and I see \r\n when I call ToString() on it. I also tried using XmlWriter.
What I would like is an XElement object which looks like
<Content><?ACE 8?>9731396</Content>
Thanks in advanced!
I've encountered exactly the same problem adding processing instructions to IDML, using .NET. Even with significant whitespace turned off I got a line break that InDesign treats as part of the text.
The only solution I have found is to save the file as XML, then open it as a text document and use a regular expression to replace >\r\n<? with just ><?. It's ugly and kludgy, but it does work - I don't have the regex to hand but you should be able to figure it out fairly quickly.
I've never had any problems adding unicode chars to XML, though. I would just use and also set the XmlWriter encoding to use unicode. See here for an example: http://bytes.com/topic/net/answers/176665-how-write-unicode-using-xmlwriter which recommends:
XmlTextWriter myWriter = new XmlTextWriter( fileStream,
new System.Text.UnicodeEncoding( false, false) );
I have a series of thousands of HTML files and for the ultimate purpose of running a word-frequency counter, I am only interested on a particular portion from each file. For example, suppose the following is part of one of the files:
<!-- Lots of HTML code up here -->
<div class="preview_content clearfix module_panel">
<div class="textelement "><div><div><p><em>"Portion of interest"</em></p></div>
</div>
<!-- Lots of HTML code down here -->
How should I go about using regular expressions in c++ (boost::regex) to extract that particular portion of text highlighted in the example and put that into a separate string?
I currently have some code that opens the html file and reads the entire content into a single string, but when I try to run a boost::regex_match looking for that particular beginning of line <div class="preview_content clearfix module_panel">, I don't get any matches. I'm open to any suggestions as long as it's on c++.

You don't.
Never use regular expressions to process HTML. Whether in C++ with Boost.Regex, in Perl, Python, JavaScript, anything and anywhere. HTML is not a regular language; therefore, it cannot be processed in any meaningful way via regular expressions. Oh, in extremely limited cases, you might be able to get it to extract some particular information. But once those cases change, you'll find yourself unable to get done what you need to get done.
I would suggest using an actual HTML parser, like LibXML2 (which does have the ability to read HTML4). But using regex's to parse HTML is simply using the wrong tool for the job.
Since all I needed was something quite simple (as per question above), I was able to get it done without using regex or any type of parsing. Following is the code snippet that did the trick:
// Read HTML file into string variable str
std::ifstream t("/path/inputFile.html");
std::string str((std::istreambuf_iterator<char>(t)), std::istreambuf_iterator<char>());
// Find the two "flags" that enclose the content I'm trying to extract
size_t pos1 = str.find("<div class=\"preview_content clearfix module_panel\">");
size_t pos2 = str.find("</em></p></div>");
// Get that content and store into new string
std::string buf = str.substr(pos1,pos2-pos1);
Thank you for pointing out the fact that I was totally on the wrong track.
I'm using a WYSIWYG to allow users to format text. This is the error-causing text:
<p><span style="line-height: 115%">This text starts with a 'T'</span></p>
The error is that the 'T' in "This", or whatever the first letter happens to be, is randomly removed when using URLDecode and saving to the DB. Removing URLDecode on the server side seems to fix it without any negative side-effects (the DB contains the same information).
The documentation says that
Query strings in HTTP are always URL-encoded.
Is this really the case? If so, why doesn't removing URLDecode seem to mess everything up?
So two questions:
Why is URLDecode causing the first text character to be removed like this (it seems to only happen when the line-height property is present)?
Do I really need (or would I even want) to use URLDecode before putting POSTed data into the database?
Edit: I made a test page to echo back the decoded text, and URLDecode is definitely removing that character, but I have no idea why.
I believe decoding is done automatically when form scope is populated. That's why characters after % (this char is used for encoding) are removed -- you are trying to decode the string second time.
For security reasons you might be interested in stripping script tags, or even cleaning up HTML using white-list. Try to search in CFLib.org for applicable functions.
