I got an asp:Textbox as well as an asp:RegularExpressionValidator on my page. Now I try to validate the input for any character of any culture i.e. the German name Günter. Unfortunately instead of the server-sided validation, the client-sided validation fails, because JavaScript is unable to match all culture letters when using \w in the regular expression pattern. Using explicit characters works (^[\wÄÜÖäüö]+$), but this is no solution, since I have to support ALL letters of ALL cultures.
To be honest I need \p{L} in JavaScript. There is a library (XRegExp) that supports this very well. But, how can I force ASP.NET to use this library instead of the default regex functions of JavaScript? I do not want to use an asp:CustomValidator and make even more work to do per form I create.
The validation in RegularExpressionValidator is done server side or client side.
When you set EnableClientScript="false" you can use "\p{L}" to validate "Günter"
<asp:TextBox ID="txtbox1" runat="server" />
<asp:Button ID="Button1" Text="Submit" runat="server" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1"
ControlToValidate="txtbox1"
ValidationExpression="\p{L}+"
EnableClientScript="false"
ErrorMessage="Error"
runat="server" />
If EnableClientScript="true", your regular expression must be ECMAScript compliant, otherwise it will fail. The behavior of ECMAScript and canonical regular expressions differs, see ECMAScript Matching Behavior.
In other words, to match unicode letters you need to set exact code of each letter or a range between letters similar to a-zA-Z.
Example: to match most of "european" letters from À-ž (see character map tool), use
<asp:RegularExpressionValidator ID="RegularExpressionValidator1"
ControlToValidate="txtbox1"
ValidationExpression="[a-zA-Z\u00c0-\u017e]+"
EnableClientScript="true"
ErrorMessage="Error"
runat="server" />
Okay, I got a solution that is not very elegant, but it works.

Thanks to mgibsonbr, his list helped me to get all the unicode ranges. (Check the script)
As you can see, it contains a huge global variable that handles unicode codes for all \p extensions, a variable for the \w parameter and a variable for the \d parameter. It's already double escaped, because the validation controls of ASP.NET store the client sided regular expression inside a variable, hence it needs to be double escaped. For more information about the unicode maps: http://www.regular-expressions.info/unicode.html
Looking to the produced client sided ASP.NET code we can see a regular expression validator produces some like these:
ContentPlaceHolder1_RegularExpressionValidator1.validationexpression = "^[\\p{L}]{0,32}$";
So I added something to the Render method of the master site:
protected override void Render(HtmlTextWriter writer)
{
this.CacheControl.RenderHeader(this.Page);
using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new StringWriter()))
{
base.Render(htmlwriter);
string html = htmlwriter.InnerWriter.ToString();
/* To support unicode \w, \d and \p{X} variables inside of asp:RegularExpressionValidator controls on client side.
* This can actually only work when your website reffers to the UnicodeRegex.js that includes
* the initialisation of the global u and w variable.
* This also only work as long as \w and \p{X} are inside of corner brackets [] in your expressions.
* Do not use \W, \D and \P{X} with it, instead negate it with ^.
*/
html = Regex.Replace(html, #"(?<=\.validationexpression = "".*?)\\\\w(?=.*?(?<!\\)"")", "\" + w + \"");
html = Regex.Replace(html, #"(?<=\.validationexpression = "".*?)\\\\d(?=.*?(?<!\\)"")", "\" + d + \"");
html = Regex.Replace(html, #"(?<=\.validationexpression = "".*?)\\\\p\{([a-zA-Z]{1,2})\}(?=.*?(?<!\\)"")", "\" + u.$1 + \"");
writer.Write(html);
}
}
When looking on the result HTML, it will hook the variable from our JS into the validationexpression variable:
ContentPlaceHolder1_RegularExpressionValidator1.validationexpression = "^[" + u.L + "]{0,32}$";
As you can see on the comments I made in the Render function, this trick / hack will restrict your usage of possibilities in the asp:RegularExpressionValidator though. So you cannot use \W, \D and \P{X} as well as you have to place \w, \d and \p{X} between corner brackets [], always.
I hope anybody will come with a better solution, but for now, it works.

Hi I have the following line:
var table = #"<table id=""table_id"" class=""display"">
which is building a table and continues on the next line but I'm just trying to append a string at the end of table_id :
var table = #"<table id=""table_id" + instance + """ class=""display"">
so the final output (if instance = 1234) should be:
<table id="table_id1234" class="display">
But I think the quotes are throwing it off. Any suggestions on how t achieve the last line?
Thanks
A string.Format method placeholder is enough to concatenate instance without cutting through quote signs ({0} is the placeholder):
var table = string.Format(#"<table id=""table_id{0}"" class=""display"">", instance);
Or you can use escape sequence \" for escaping quotes without string literal:
var table = "<table id=\"table_id" + instance + "\" class=\"display\">"
Result:
<table id="table_id1234" class="display">
Demo: .NET Fiddle
Try to use escape character for double quote(\") using this code:
var id = "1234";
var table = "<table id=\"table_id" + id + "\" class=\"display\">";
Here is an online tool for converting string to escape/unescape:
https://www.freeformatter.com/java-dotnet-escape.html
So you can copy the result and place your variables.
I think the best idea and newest idea for this situation is $ sign before your text and with this sign you dont need to extra sign in your string
example
vat table = $"<table id='table_id{instance}' class='display'">
# is used to escape double quotes from one string but in your example, you are actually concatenating three different strings, soyou should escape the third string as well like this:
var table = #"<table id=""table_id" + instance + #" "" class=""display"" >";
Alternatively, you could also use the StringBuilder class which is more memory efficient and might make your strings easier to read.
I have a big file that has a bunch of data in it, but essentially what I would like to do is to grab only parts of it, let me explain what parts I'm interested in:
(imagine "x" as an IP Address)
(imagine "?" as any alphanumerical character /w any length)
(imagine "MD5" as an MD5 hash)
(Actual -not literally though- text file below)
'xxx.xxx.xxx.xxx'
xxxxxxxxxx
'?'
'?'
'MD5'
Now my inquiry is the following one, How could I identify the line
'xxx.xxx.xxx.xxx'
anywhere at the beginning inside a file and then automatically write to another file both of the '?' entries and the 'MD5' entry for each IP Address instances found.
So in a nutshell, the program should start at the beginning of the file, read the contents, if it hits an IP Address (Regex: '\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b' works fine for me), skip one line below, then start copying the other data to another file until it hits the MD5 entry (Regex: '[a-f0-9]{32}' works fine for me), then iterate again from that point and so on looking for another instance of an IP Address etc, etc. It should keep doing that until it reaches the end of the file.
I'm trying to do this myself but I don't even know where to start, or methods of doing it at all.
You can use the following to match the content that you are looking for.. and copy it to the desired location/ file:
('\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b')(\s*.+\s*)([\s\S]*?)('\b[a-f0-9]{32}\b')
And extract $1$3$4
See DEMO
Code:
String regex = "('\\b\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\b')(\\s*.+\\s*)([\\s\\S]*?)('\\b[a-f0-9]{32}\\b')";
Pattern pattern = Pattern.compile(regex);
Matcher m = pattern.matcher(myString);
while (m.find()) {
System.out.println("end(): " + m.group(1));
//System.out.println("end(): " + m.group(2));
System.out.println("end(): " + m.group(3));
System.out.println("end(): " + m.group(4));
}
Given the fact that your file is machine generated and that the overall pattern is pretty specific, I don't think it's necessary to be overly specific with the IP address.
Matching it as "a bunch of digits and dots in single quotes" is probably enough, in the context of the rest of the pattern (*).
Here is an expression that matches your entire requirement into named groups:
^'(?<IP>[\d.]+)'\s+
^(?<ID>\w*)\s+
^'(?<line1>\w*)'\s+
^'(?<line2>\w*)'\s+
^'(?<MD5>[A-Fa-f0-9]{32})'
Use it with the Multiline and IgnorePatternWhitespace regex options (the latter means you can keep the regex layout for better readability).
(*) Besides, regex patterns for IP addresses are literally all over the place, in countless examples. Of course you can use something more sophisticated than '[\d.]+' if you think it's necessary.
I have tried out this in Java as below.
public class TestRegex
{
/**
* #param args
*/
public static void main(String[] args)
{
String input = "assasasa 123.234.223.223 333 aad sddsf 343sdd sds23343 ssdfs33344 MD5=aas jjsjjdjd 143.234.223.223 333 aad sddsf 343sdd sds23343 ssdfs33344 MD5=asas";
String regexPattern = "(\\b[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\b).*?([A-Z a-z]+[0-9]+=.*?\\s)";
Matcher m = null;
Pattern pattern = Pattern.compile(regexPattern);
m = pattern.matcher(input);
// System.out.println(matcher.toString());
while (m.find()) {
System.out.println("start(): " + m.start());
System.out.println("end(): " + m.end());
System.out.println("end(): " + m.toString());
System.out.println("end(): " + m.group(1));
System.out.println("end(): " + m.group(2));
}
}
}
Hi and thanks in advance,
I have a some latitudes and longitudes that look something like this: -81.7426684 W - -81.6901007 W that I am trying to validate using asp rangevalidation using the minimum and maximum values attributes.
asp:
<asp:TextBox ID="txtLon" runat="server" CssClass="container-input-field" SkinID="NumTextUpDown"></asp:TextBox>
<asp:RangeValidator ID="RangeLong_Validator" runat="server" ControlToValidate="txtLon"
CssClass="errorMessage" ToolTip="Longitude Out Of Range" Type="String">
<img alt="" src="images/no.png" />
</asp:RangeValidator>
c#:
RangeLong_Validator.MinimumValue = "" + getCompassLon(range.LowLong); // -81.7426684 W
RangeLong_Validator.MaximumValue = "" + getCompassLon(range.HighLong); // -81.7426684 W
rangeSetUp_Lon.Text = RangeLong_Validator.MinimumValue + " - " + RangeLong_Validator.MaximumValue;
I get this error: System.Web.HttpException: The MaximumValue -81.6901007 W cannot be less than the MinimumValue -81.7426684 W of RangeLong_Validator. I think its not counting the negative sign.
I have to using strings because I might have a formats that looks like this as well: 25 32' 13.2" E, 124 59.94' E
I am up for any ideas.
In general, when using RangeValidator for numbers, you should specify Type="Integer" or Type="Double", but not Type="String".
However, in your specific case the subject data is more complicated than just a number - it has " W" at the end, and as you mentioned the format could be even more complicated.
Therefore, in order to properly validate such data you should use CustomValidator. This way you'll be able to parse the data and test it against any rules.
I am creating data driven xaml using RazorEngine.
However, I cannot get this to work:
string template = "<k t=\" #Raw(Model.Name) \" ";
var model = new { Name = "CS
" };
string result = Razor.Parse(template, model);
this causes "result" to become
<k t="CS "
I do not want the "&" to be turned into
#amp;
If I remove any of the following:
the starting character "<"
the space between "k" and "t"
the \"
....then the razor engine parser Raw() function is behaving correctly by not converting "&" into "&"
I was also thinking that I could help Razor understand my intent better by using a code block #{} instead of just #.
However, I haven't figured how I can make a code block emit text to Razor output.
You don't need to do anything & is actually &.
if you try this code you will see that it outputs &
var str = HttpUtility.HtmlDecode("&")
See http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references and http://en.wikipedia.org/wiki/Character_encodings_in_HTML for more info.
I have below code behind in c#
if (Session["cmpDictionaryTitle"]!= null)
{
downloadLinks.Text += #"<li><a onclick='pageTracker._trackEvent('dictionary', 'spanish');' target ='_blank' href=" + Session["cmpDictionaryTitle"] + ">" + GetResourceString("c_DictionaryPDFName") + "</a></li>";
}
I am trying to make below <a> link as shown below:
<li><a target ="_blank" href="/spa/Images/Diccionario_tcm25-18044.pdf" onclick="pageTracker._trackEvent('dictionary', 'spanish');">Diccionario de Español-Inglés GRATIS</a></li>
However my c# code is generating below output when html page get renders, the reason is that I am not able to put proper quotes in my code behind.
<li><a );="" spanish="" ,="" dictionary="" onclick="pageTracker._trackEvent(" href="/spa/Images/Diccionario_tcm25-18044.pdf" target="_blank">Diccionario de Español-Inglés GRATIS</a></li>
Can you please suggest how can I achieve above result in code behind.
Thanks & Best Regards
To use a double-quote in a string built in code, either:
Escape the double-quote character
like this: "\"".
Escape the double-quote character like this:
"""" (when using # to create a verbatim
string literal).
Examples:
// These are both rendered as <a target="_blank" />
Response.Write("<a target =\"_blank\" />");
Response.Write(#"<a target =""_blank"" />");
Here's your original code using backslash-escaped double-quotes for all the attributes (I've chosen the first approach and removed the leading #):
if (Session["cmpDictionaryTitle"]!= null) {
downloadLinks.Text += "<li><a onclick=\"pageTracker._trackEvent('dictionary', 'spanish');\" target =\"_blank\" href=\"" + Session["cmpDictionaryTitle"] + "\">" + GetResourceString("c_DictionaryPDFName") + "</a></li>";
}
Finally, I recommend reading Jon Skeet's excellent article "Strings in .NET and C#."
<a
onclick="pageTracker._trackEvent('dictionary', 'spanish');"
target ="_blank"
href="<%= Server.HtmlEncode((string)Session["cmpDictionaryTitle"]) %>">
<%= Server.HtmlEncode(GetResourceString("c_DictionaryPDFName")) %>
</a>
UPDATE:
You could also build tags using XElement:
var tag = new XElement("li",
new XElement("a",
new XAttribute("onclick", "pageTracker._trackEvent('dictionary', 'spanish');"),
new XAttribute("target", "_blank"),
new XAttribute("href", Session["cmpDictionaryTitle"]),
new XText(GetResourceString("c_DictionaryPDFName"))
)
);
downloadLinks.Text += tag.ToString();
I resolved the above issue with below code:
downloadLinks.Text = string.Format("<li> <a target=\"_blank\" href=\"{0}\" onclick=\"pageTracker._trackEvent('dictionary','spanish');\">{1}</a> </li>",Session["cmpPDFLink"],GetResourceString("c_DictionaryPDFName"));
Cheers!
Your first example is using single quotes for the attribute quotes, and within the value itself, so just change one of them to use double quotes, e.g.:
<a onclick="pageTracker._trackEvent('dictionary', 'spanish');" ...
