I'm looking for some regex to retrieve the GUID from the following URL
GetUploadedUserAudioIdfriendlyName=eb0c5663-a9c3-4321-8c0e-5ffbfb3139fc
I've so far got
GetUploadedUserAudioId\?friendlyName=([A-Fa-f0-9-]*)
but this is returning the full url
This is the image of where the expressions are to give you an idea of what I am trying to do.
Don't use a regex for this.
Assuming you're using C#.NET, use the static ParseQueryString() method of the System.Web.HttpUtility class that returns a NameValueCollection.
Uri myUri = new Uri("http://www.example.com?GetUploadedUserAudioIdfriendlyName=eb0c5663-a9c3-4321-8c0e-5ffbfb3139fc");
string param1 = HttpUtility.ParseQueryString(myUri.Query).Get("param1");
Check this documentation
EDIT: If you want it as a Guid after that, then cast it to one:
var paramGuid = new Guid(param1);

I'm trying to extract the part of url (To be more specific, I'm trying to extract the value of page_info parameter in the url which is next to rel="next"
String testUrl = "<https://demo.myshopify.com/admin/api/2022-01/products.json?limit=10&page_info=eyJkaXJlY3Rpb24iOiJwcmV2IiwibGFzdF9pZCI6NjczMDU4MDcyMTc1NCwibGFzdF92YWx1ZSI6IjE4SyBHb2xkIFBsYXRlZCBCcmFjZWxldCJ9>; rel='previous', <https://demo.myshopify.com/admin/api/2022-01/products.json?limit=10&page_info=eyJkaXJlY3Rpb24iOiJuZXh0IiwibGFzdF9pZCI6NjczMDIyNzcxMjA5MCwibGFzdF92YWx1ZSI6IjE4SyBHb2xkIFBsYXRlZCBIZWFydCBQZW5kYW50IE5lY2tsYWNlIn0>; rel='next'";

I tried to split the url by using split function on String but that would also bring the angle bracket with it. I'm trying to extract only page_info= parameter value which is for rel="next"
I know this has to do something with regex but I'm not really good at it! Any help would be really appreciated
I grabbed that url from header response (paginated REST API), it returns two page_info parameters (one for next and other one for previous page) I'm trying to extract value for next page. Splitting the url didn't help me
thank you
An alternative approach is to use Uri.parse to parse the URL:
void main() {
String testUrl = "<https://demo.myshopify.com/admin/api/2022-01/products.json?limit=10&page_info=eyJkaXJlY3Rpb24iOiJwcmV2IiwibGFzdF9pZCI6NjczMDU4MDcyMTc1NCwibGFzdF92YWx1ZSI6IjE4SyBHb2xkIFBsYXRlZCBCcmFjZWxldCJ9>; rel='previous', <https://demo.myshopify.com/admin/api/2022-01/products.json?limit=10&page_info=eyJkaXJlY3Rpb24iOiJuZXh0IiwibGFzdF9pZCI6NjczMDIyNzcxMjA5MCwibGFzdF92YWx1ZSI6IjE4SyBHb2xkIFBsYXRlZCBIZWFydCBQZW5kYW50IE5lY2tsYWNlIn0>; rel='next'";
// Extract just the URL.
var match = RegExp(r'<([^>]*)>').firstMatch(testUrl);
if (match != null) {
var uri = Uri.parse(match.group(1)!);
print(uri.queryParameters['page_info']); // Prints: eyJkaXJlY3Rpb24iOiJ...
}
}
Note that the above wouldn't need any of the RegExp code if testUrl were a proper URL without the angle brackets and rel='next' junk.
the regEx pattern page_info=([\w]+)
gives you

I'm trying to do a 'like' query in mongodb. I see that's done with a regexp so I'm trying to set it like this:
$scope.clients = Client.query({
q:angular.toJson({
name: RegExp($routeParams.str)
})
});
The thing is angular.toJson function does not get any regexp:
http://plnkr.co/edit/idXMT1
Is there any other way to do that?
From my understanding of your question, you want your JSON object to contain the regular expression as a string?
In that case, you can manually convert it to a string in the declaration, i.e:
$scope.object = angular.toJson({
"param" : new RegExp(str).toString()
});
See updated plunk:
http://plnkr.co/edit/yLogI8
I finally found a solution.
The problem is using the toJon function as it does not allow any key starting with / or $ so the solution is avoiding the use of this function and just write the object as a string
$scope.clients = Client.query({
q:'{src:{$regex:"' + $routeParams.str + '"}}'
};
How can I fix this code to work?
public void check(WebDriver driver) {
driver.findElement(By.xpath("//a[matches(#href,'/staff/transcript/\\d{5}//.pdf')]")).click();
}
I must find a link where 5-digit indentifier varies.
Try to get href attribute
parse that string to get that 5 digit identifier
use that identifier and construct your locator and click.
String href=driver.findElement(By.xpath("//a[contains(#href,'/staff/transcript/')][contains(#href,'.pdf')]")).getAttribute("href");
String identifier=href.substring(href.lastIndexOf("/")+1,href.indexOf("."));
driver.findElement(By.xpath("//a[matches(#href,'/staff/transcript/"+identifier+"//.pdf')]")).click();
one possible solution to your problem:
using js iterate through all tags and find first which corresponds to your regex.
pubic String getLocatorByRegExp(){
JavascriptExecutor js = (JavascriptExecutor) driver;
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("var regex = /^\d{5}$/");
stringBuilder.append("var x=document.getElementsByTagName('a');");
stringBuilder.append("for(var t = 0; t <x.length; t++){if(regex.test(parseInt(x[t].text()))) return x[t].text().toString();} ");
String res= (String) js.executeScript(stringBuilder.toString());
return res;
}
String properLinkText = getLocatorByRegExp();
driver.findElement(By.xpath(//a[contains(text(),properLinkText)])).click()
Quite complicated approach. But it seems to me that it is possible to find simplier solution.
Is it 5-digit indentifier unique on the page ( i mean only one element on the page ?)
If so, it is easy to find css locator or xpath to this element.
Provide please some piece of your html and point out element you need to click on.
I'm using selenium RC and I would like, for example, to get all the links elements with attribute href that match:
http://[^/]*\d+com
I would like to use:
sel.get_attribute( '//a[regx:match(#href, "http://[^/]*\d+.com")]/#name' )
which would return a list of the name attribute of all the links that match the regex.
(or something like it)
thanks
The answer above is probably the right way to find ALL of the links that match a regex, but I thought it'd also be helpful to answer the other part of the question, how to use regex in Xpath locators. You need to use the regex matches() function, like this:
xpath=//div[matches(#id,'che.*boxes')]
(this, of course, would click the div with 'id=checkboxes', or 'id=cheANYTHINGHEREboxes')
Be aware, though, that the matches function is not supported by all native browser implementations of Xpath (most conspicuously, using this in FF3 will throw an error: invalid xpath[2]).
If you have trouble with your particular browser (as I did with FF3), try using Selenium's allowNativeXpath("false") to switch over to the JavaScript Xpath interpreter. It'll be slower, but it does seem to work with more Xpath functions, including 'matches' and 'ends-with'. :)
You can use the Selenium command getAllLinks to get an array of the ids of links on the page, which you could then loop through and check the href using the getAttribute, which takes the locator followed by an # and the attribute name. For example in Java this might be:
String[] allLinks = session().getAllLinks();
List<String> matchingLinks = new ArrayList<String>();
for (String linkId : allLinks) {
String linkHref = selenium.getAttribute("id=" + linkId + "#href");
if (linkHref.matches("http://[^/]*\\d+.com")) {
matchingLinks.add(link);
}
}
A possible solution is to use sel.get_eval() and write a JS script that returns a list of the links. something like the following answer:
selenium: Is it possible to use the regexp in selenium locators
Here's some alternate methods as well for Selenium RC. These aren't pure Selenium solutions, they allow interaction with your programming language data structures and Selenium.
You can also get get HTML page source, then regular expression the source to return a match set of links. Use regex grouping to separate out URLs, link text/ID, etc. and you can then pass them back to selenium to click on or navigate to.
Another method is get HTML page source or innerHTML (via DOM locators) of a parent/root element then convert the HTML to XML as DOM object in your programming language. You can then traverse the DOM with desired XPath (with regular expression or not), and obtain a nodeset of only the links of interest. From their parse out the link text/ID or URL and you can pass back to selenium to click on or navigate to.
Upon request, I'm providing examples below. It's mixed languages since the post didn't appear to be language specific anyways. I'm just using what I had available to hack together for examples. They aren't fully tested or tested at all, but I've worked with bits of the code before in other projects, so these are proof of concept code examples of how you'd implement the solutions I just mentioned.
//Example of element attribute processing by page source and regex (in PHP)
$pgSrc = $sel->getPageSource();
//simple hyperlink extraction via regex below, replace with better regex pattern as desired
preg_match_all("/<a.+href=\"(.+)\"/",$pgSrc,$matches,PREG_PATTERN_ORDER);
//$matches is a 2D array, $matches[0] is array of whole string matched, $matches[1] is array of what's in parenthesis
//you either get an array of all matched link URL values in parenthesis capture group or an empty array
$links = count($matches) >= 2 ? $matches[1] : array();
//now do as you wish, iterating over all link URLs
//NOTE: these are URLs only, not actual hyperlink elements
//Example of XML DOM parsing with Selenium RC (in Java)
String locator = "id=someElement";
String htmlSrcSubset = sel.getEval("this.browserbot.findElement(\""+locator+"\").innerHTML");
//using JSoup XML parser library for Java, see jsoup.org
Document doc = Jsoup.parse(htmlSrcSubset);
/* once you have this document object, can then manipulate & traverse
it as an XML/HTML node tree. I'm not going to go into details on this
as you'd need to know XML DOM traversal and XPath (not just for finding locators).
But this tutorial URL will give you some ideas:
http://jsoup.org/cookbook/extracting-data/dom-navigation
the example there seems to indicate first getting the element/node defined
by content tag within the "document" or source, then from there get all
hyperlink elements/nodes and then traverse that as a list/array, doing
whatever you want with an object oriented approach for each element in
the array. Each element is an XML node with properties. If you study it,
you'd find this approach gives you the power/access that WebDriver/Selenium 2
now gives you with WebElements but the example here is what you can do in
Selenium RC to get similar WebElement kind of capability
*/
Selenium's By.Id and By.CssSelector methods do not support Regex and By.XPath only does where XPath 2.0 is enabled. If you want to use Regex, you can do something like this:
void MyCallingMethod(IWebDriver driver)
{
//Search by ID:
string attrName = "id";
//Regex = 'a number that is 1-10 digits long'
string attrRegex= "[0-9]{1,10}";
SearchByAttribute(driver, attrName, attrRegex);
}
IEnumerable<IWebElement> SearchByAttribute(IWebDriver driver, string attrName, string attrRegex)
{
List<IWebElement> elements = new List<IWebElement>();
//Allows spaces around equal sign. Ex: id = 55
string searchString = attrName +"\\s*=\\s*\"" + attrRegex +"\"";
//Search page source
MatchCollection matches = Regex.Matches(driver.PageSource, searchString, RegexOptions.IgnoreCase);
//iterate over matches
foreach (Match match in matches)
{
//Get exact attribute value
Match innerMatch = Regex.Match(match.Value, attrRegex);
cssSelector = "[" + attrName + "=" + attrRegex + "]";
//Find element by exact attribute value
elements.Add(driver.FindElement(By.CssSelector(cssSelector)));
}
return elements;
}
Note: this code is untested. Also, you can optimize this method by figuring out a way to eliminate the second search.
I'm working on WatiN automation tool. I'm having problem in regular expression. I've situation where i have to enter some text and click on a button in the popup window. I'm using AttachToIE method and URL attribute("http://192.168.25.10:215/admin/SelectUsers.aspx?Type=FeedbackID=ef5ad7ef5490-4656-9669-32464aeba7cd") of the popup to attach to the popup.
The problem is each time the popup appears the ID value in the URL changes. So i'm not able to access the popup. can anyone plz help with this by giving me Regular Expression for the changing value of ID in the below URL
("http://192.168.25.10:215/admin/SelectUsers.aspx?Type=FeedbackID=ef5ad7ef5490-4656-9669-32464aeba7cd")
thanking you
It appears that you have a URL with 2 query string parameters Type and ID and your pattern is:
"http://192.168.25.10:215/admin/SelectUsers.aspx?Type=Feedback&ID={some id}"
You can use the Find.ByUrl() attribute constraint method and pass it to AttachToIE() as shown below with the regex for matching that pattern.
string url = "http://192.168.25.10:215/admin/SelectUsers.aspx?Type=Feedback&ID="
Regex regex = new Regex(url + "[a-z0-9]+", RegexOptions.IgnoreCase);
IE ie = IE.AttachToIE(Find.ByUrl(regex));
string baseUrl ="http://192.168.25.10:215/admin/SelectUsers.aspx?Type=FeedbackID="
Regex urlIE= new Regex(baseUrl + "[\\wd]+", RegexOptions.IgnoreCase);
IE ie = IE.AttachToIE(Find.ByUrl(urlIE);
I'm not familiar with WatiN but it looks like it's runs on .Net so perhaps this might help?
var desiredId = "000000000000-0000-0000-000000000000";
var url = "http://192.168.25.10:215/admin/SelectUsers.aspx?Type=FeedbackID=ef5ad7ef5490-4656-9669-32464aeba7cd&someMoreStuff";
var pattern = #"(?i)(?<=FeedBackId=)[-a-z0-9]+";
var result = Regex.Replace(url, pattern, desiredId);
Console.WriteLine(result);
//Output: http://192.168.25.10:215/admin/SelectUsers.aspx?Type=FeedbackID=000000000000-0000-0000-000000000000&someMoreStuff
The following pattern should have the same affect but is more defensive. It should only match stuff in the query string, it requires the id to be 35 characters and won't match similar parameter names like "PreviousFeedBackId".
var pattern = #"(?i)(?<=\?.*\bFeedBackId=)[-a-z0-9]{35,35}\b";
If you just want to extract the id:
var id = Regex.Match(url, pattern).Value;
Console.WriteLine(id);
//output: ef5ad7ef5490-4656-9669-32464aeba7cd
WatiN has a feature where in we can use the url by neglecting the query string. Below is the code which is working fine for me.
string baseUrl = "http://192.168.25.10:215/admin/SelectUsers.aspx";
IE ie = IE.AttachToIE(Find.ByUrl(baseUrl,true));
