How I can call webservice from voice xml (vxml) document. I am using an opensource IVR project and I need to run a webservice for any given option from within the vxml document.
This is similar to this query;
how can I call a webservice from voiceXML?
However, solution is provided there but it is not
You cannot call a web service directly from a VoiceXML application. There are generally two approaches for getting data into a VoiceXML application:
Use the data element tag to make an http request. The result must be XML. You will need to parse the result with the provided DOM functions. Note, some browsers have extended features to facilitate XML parsing. This also requires a VoiceXML 2.1 compliant browser.
Transfer control to a dynamic bit of server code that returns VXML to be processed populating your desired variables. This can be done with a goto element or subdialog element.
Your question is incomplete, but I suspect I know what's bothering you.
I get information from a webservice by using
<data name="return_data" srcexpr="some_url" method="post" namelist="var1 var2 var3" />
The data I get back is inside the return_data variable. In my case, the data are in XML format, and I use JavaScript functions to extract the data I need.
As an aside, for maintainability, re-usability, and ease of reading, I personally find it useful to create separate files for the JS functions and include them via <script> into my root VoiceXML document.

I am trying to transform an HTML report into XML, but some javascript in the file is throwing errors, due to statements with a less-than character (e.g., for(var i=0; i<els.length;i++) ). I thought I could eliminate the javascript with the following template, which should remove entire script nodes:
<xsl:template match="script"/>
I assumed the XSLT processor would simply skip over the entire script nodes, but it's still throwing the same errors. I also tried adding this one:
<xsl:template match="script/text()"/>
No luck. If I manually remove all the javascript from the file, my transform works, but that's not practical as I need to create and run a daily automated process on these HTML files to extract some data in the HTML tables.
As a general rule, XSLT will only process well-formed XML input: it's not designed to process other formats like HTML.
However, XSLT will generally accept input from a parser that delivers a stream of events that looks sufficiently like an XML stream. This allows parsers like TagSoup and validator.nu to be used as a front-end to your XSLT processor.
Saxon packages this up with a parse-html() function that invokes TagSoup to parse HTML input and turn it into a DOM-like tree (actually an XDM tree) that it can process as if it came from XML.
validator.nu is a more up-to-date HTML parser than TagSoup, but you would have to do a little more work to integrate that.
Question was answered by Martin Honnen in the comments:
oxygenxml.com/doc/versions/18.1/ug-editor/tasks/… suggests there is an HTML import feature so try whether that helps. Of course there are standalone applications like HTML Tidy I think you can use outside of the XSLT processsing to first convert your HTML to XHTML.
I created a http request step in soapui which is an html page from which I need to extract one single value from
<span class="result">12345<span>
I'm thinking about using groovy,is it the best way ? If yes I'm beginner in both soapui and groovy, any snippet code to get started (how to get html Content from http request step, how to parse in groovy) thanks.
If you feel more comfortable with Groovy, then go for it!
SoapUI internally represents almost everything as XML. Therefore the easiest way to manipulate things in SoapUI is using XPath. In your case, you could probably use a Property Transfer step to extract //span[#class="result"].
Siking answer worked setting the source 'property' to ResponseAsXml along with XPath expresions, as for common HTML XPath expressions there's a resource online at
https://devhints.io/xpath
For the development of a custom reverse proxy (written in C++) I want to do a realtime translation of URIs in HTML content. For example if I want to access a ressource on http://myserver/ using http://my-reverse-proxy/myserver, all absolute and toplevel links like http://myserver/somecontent1.ext or /somecontent2.ext need to be modified.
An HTML tag
<img src="/sample.png">
would therefore be translated to
<img src="/myserver/sample.png">
From my point of view there are to approaches:
1) Using regular expressions and string replacement to find all related HTML tags and their paths using capture groups and do some string replacement.
2) Parse entire HTML content, do some transformation on the parse tree and pretty-print the result back to a valid HTML ressource.
And this is what this question is all about: Do you have any experiences what solution might be faster and maybe even more reasonable? Do you know a framework I might use to not reinvent the wheel? As this process should be used later for CSS and XML-based ressources as well, it should not be a HTML-depend solution.
Thanks in advance!
Proxy servers generally work by being servers. They handle all HTTP requests, modify the requested URLs, and then pass the modified request on to the server on the other side.
You should stick to this paradigm. It is far easier and more efficient than mucking around with the files themselves. Anything that is being done real-time can be done at the point of the request.
Also, it should probably be asked: why a custom reverse proxy? Such things exist already.
In my C++ app I'm embedding (via COM) a web browser (Internet Explorer) control (CLSID_WebBrowser).
I can display my own html in that control by using IHTMLDocument2::write() method but if the html has <img src="foo.png"> element, it's not displayed.
I assume there is a way for me to provide the data for foo.png somehow to the web control, but I can't find the right place to hook this functionality?
I need to be in full control of providing the content of foo.png, so work-arounds like using res:// protocol or saving to disk and using file:// protocol are not good enough. I just want to plug my code somehow so that when embedded CLSID_WebBrowser control sees <img src="foo.png"> in html data given with IHTMLDocument2::write() it will ask me to provide this data.
To answer my own question, the solution that finally worked for me is:
register custom IInternetProtocol/IInternetProtocolInfo/ via custom IClassFactory given to IInternetSession::RegisterNameSpace(). For reasons that seem like a bug to me, it has to be a protocol already known to IE (I've chosen "its") even though it would be much better if it was my own, unique namespace.
feed html data via custom IMoniker through IPersistentMoniker::Load() and make sure that IMoniker::GetDisplayName() (which is a base url according to which relative links in provided html will be resolved) starts with that protocol scheme (in my case "its://"). That way relative link "foo.png" in the html data will be its://foo.png to IE which will make urlmon call IInternetProtocol::Start() and IInternetProtocol::Read() to ask for the data for that url.
This is all rather complicated, you can look at the actual (BSD-licensed) code here:
http://code.google.com/p/sumatrapdf/source/browse/trunk/src/utils/HtmlWindow.cpp
You can embed a small webserver such as mongoose and reference those impage from there.
In mongoose, you can attach callback to specific path, thus returning images from C++ code.
We use this for our debugging tools, where each images is accessible from a web interface
The easiest solution would be a Data URI. You'd inline out the image directly with IHTMLDocument2::write().
First of all: I'm on Ektron CMS v8.1
I'm having a problem with dynamicly adding translated content to the cms via the Webservice API. I can perfectly add xml content by using the following object and method:
ContentSoapClient csc = new ContentSoapClient("ContentSoap");
csc.AddContent3(...);
I specify a language and the xml content gets inserted. But now I want to add a translated version of the xml to the cms. So I want it to have the same contentId!
Anyone has an idea on this? The only method in the csc object that recieves a contentId is 'csc.AddContent2(..)' But that doesn't import anything and just gives me an error saying my xml is incorrect. While my xml is correct..I checked it!
Thanks!
Found the answer..
Ektron apparantly uses alot of asmx files and I only checked the "/workarea/webservices/WebServiceAPI/Content/Content.asmx" webservice. I found the method 'AddTranslatedXMLContent()' I need in the "/Workarea/webservices/ContentWS.asmx" webservice.
I wish they just cleaned up their API... Would save us a lot of trouble.
Firstly, I haven't used the ContentSoapClient class and can't find any documentation on it.
Ektron often takes a language id when you create the API object. See if the ContentSoapClient contructor can take a Language Id.
