The current XML Helper in CakePHP doesn't give you the ability to specify if you want the whitespace to be significant or non-significant. Normally it wouldn't matter, but I'm working with a strict API that requires certain values to have no excess characters surrounding the value (no \n's or \t's). I'd like to modify the Cake source to support this ability, and if anyone has done this before and has any tips or advise on how to start, I'd appreciate it. Actually I believe the most helpful thing would be if someone has a flowchart of how Cake comes together (ie: starts in index.php and flows through router.php or what-not). I'd like to get a better understanding of how Cake is constructed (even from a high level).
Thanks!
If you want to change one of the built-in helpers, just copy it into your /app/views/helpers/ directory and edit it from there. The version in your app will be used instead of the original.

I'm getting an error when uploading my customized policy, which is based on Microsoft's SocialAccounts example ([tenant] is a placeholder I added):
Policy "B2C_1A_TrustFrameworkExtensions" of tenant "[tenant].onmicrosoft.com" makes a reference to ClaimType with id "client_id" but neither the policy nor any of its base policies contain such an element
I've done some customization to the file, including adding local account signon, but comparing copies of TrustFrameworkExtensions.xml in the examples, I can't see where this element is defined. It is not defined in TrustFrameworkBase.xml, which is where I would expect it.
I figured it out, although it doesn't make sense to me. Hopefully this helps someone else running into the same issue.
The TrustFrameworkBase.xml is not the same in each scenario. When Microsoft documentation said not to modify it, I assumed that meant the "base" was always the same. The implication of this design is: If you try to mix and match between scenarios then you also need to find the supporting pieces in the TrustFrameworkBase.xml and move them into your extensions document. It also means if Microsoft does provide an update to their reference policies and you want to update, you need to remember which one you implemented originally and potentially which other ones you had to pull from or do line-by-line comparison. Not end of the world, but also not how I'd design an inheritance structure.
This also explains why I had to work through previous validation errors, including missing <DisplayName> and <Protocol> elements in the <TechnicalProfile> element.
Yes - I agree that is a problem.
My suggestion is always to use the "SocialAndLocalAccountsWithMfa" scenario as the sample.
That way you will always have the correct attributes and you know which one to use if there is an update.
It's easy enough to comment out the MFA stuff in the user journeys if you don't want it.
There is one exception. If you want to use "username" instead of "email", the reads/writes etc. are only in the username sample.
Could someone point me in the right direction please?
I am trying to extract specific text/numbers from a json payload. I can access/isolate the full string of text by using triggerFormDataValue('text').
The text in question may contain 'sendSMS 1122334455 actual message' as its actual value
Is there anyway, in a logic app flow, to break the text into its component parts?
(sendsms, 1122334455 and actual message)
n.b. I have already tried interacting with the cognitive analysis app for key word searches but that doesn't return the number, nor the full sting, just the key words.
thanks
For more complex logic like the one you have, I would recommend to create an Azure Function. This is a light-weight solution that will offer you the flexibility of a microservice which offers you this possibility.
To extract the numbers, you may use a regular expression.
Edit:
I've found a similar question here on SO, but the conclusion is very similar.
I've done some small research now and it seems Microsoft deliberately does't put too much text parsing functionality in Logic Apps in order to avoid them being too complex. You might have a chance if you put them in JSON notation, but I think the better option would be to go to Azure functions, since it provides reuseability as well.
If that's all you need to do, you can use the split() function. Details: String Functions...split
Ui:include and xhtml based tag (the one with source elt) seem to be much the same for me. Both allow to reuse piece of markup. But I believe there should be some reason for having each. Could somebody please briefly explain it? (I guess if I read full facelets tutorial I will learn it, but I have not time to do it now, so no links to lengthy docs please :)
They are quite similar. The difference is mainly syntactical.
After observing their usage for some time it seems the convention is that fragments that you use only in a single situation are candidates for ui:include, while fragments that you re-use more often and have a more independent semantic are candidates for a custom tag.
E.g.
A single view might have a form with three sections; personal data, work history, preferences. If the page becomes unwieldy, you can divide it into smaller parts. Each of the 3 sections could be moved to their own Facelet file and will then be ui-include'ed into the original file.
On the other hand, you might have a specific way to display on image on many views in your application. Maybe you draw a line around it, have some text beneath it etc. Instead of repeating this over and over again you can abstract this to its own Facelet file again. Although you could ui:include it, most people seem to prefer to create a tag here, so you can use e.g. <my:image src="..." /> on your Facelets. This just looks nicer (more compact, more inline with other components).
In the Facelets version that's bundled with JSF 2.0, simple tags can be replaced by composite components. This is yet a third variant that on the first glance looks a lot like custom tags, but these things are technically different as they aren't merely an include but represent true components with declared attributes, ability to attach validators to, etc.

I want to know how i can write a program to lookup all the input fields of a website. Any website. and then can fill them in. I can write the simple webbrowser in vbs but how can i analyse the input fields. even better would be is i could click the lookup field and it puts the name of it in a box..... that would be ideal.
Anyone can help? thanks :)
Are you sure you want to do this in C?
I ask because it is not easy. First of all, you need to be able to run the HTTP GET request against the webpage you wish to view. For this, you probably need libcurl; you definitely don't want to be writing from scratch at any rate.
Next, you need to process the html you get, finding all input fields. You do NOT want to do this using regular expressions, if anything for the sake of bobince's blood pressure. HTML is not a regular language is the bit you need to take away - you need an xml parser. Enter libxml. I'm sure there are other xml libraries out there, and even libraries for parsing html.
Finally, having done that (got the fields etc) you need to be able to populate them and submit the correct request as per the ACTION and METHOD parameters of the FORM.
This is of course assuming you know what the fields should be formatted with. And it also assumes nothing else is going on. If you have a javascript validated web form (I sincerely hope they're validating on the request too, but they might provide feedback via JS) you won't benefit from that (unless you're going to integrate JS, in which case you might as well write a browser).
This is not a trivial task and it is the reason there are accessibility standards for HTML, because otherwise it becomes tricky to interpret the form without human interaction.
Of course, this all assumes said html is well formed, which isn't always the case...
I might suggest another approach. BeautifulSoup is a well known Python web scraping library that works very well. Python as a language allows easier string manipulation too, which will dramatically cut down your development time. I'd suggest giving the need to use C some serious thought given the size and complexity of the task you want to undertake vs your need to get a result quickly. If you have a lot of time, by all means go for C.
I have a code library that makes heavy use of XPathNavigator to parse some specific xml document. The xml document is cross-referenced, meaning that an element can reference another which has not yet been encountered during parsing:
<ElementA ...>
<DependentElementX id="1234">
</ElementA>
<ElementX id="1234" .../>
The document doesn't really look like this, but the point is that 1) there is an xml schema that enforces the overall document structure, 2) elements inside the document can reference each other using some IDs, and 3) there is quite a few such cross references between different elements in the document.
The document is parsed in two phases. In the first pass I walk through the document
XPathDocument doc = ...;
XPathNavigator nav = doc.CreateNavigator();
nav.MoveToRoot();
nav.MoveToFirstChild()...
and occasionally 'bookmark' the current position (element) in the document using XPathNavigator.Clone() method. This gives me a lightweight instance of an XPathNavigator which I can store somewhere and use later to jump back to a particular place (element) in my document.
Once I have enough information collected in the first pass (for example, I have made sure there is indeed an ElementX with an id='1234'), I jump back to saved bookmarks (using those saved XPathNavigators) and complete the parsing.
Well, now I'm about to use this library in Silverlight 3.0 and to my horror the XPathNavigator is not in the System.Xml assembly.
Questions:
1) Am I missing something obvious (i.e. XPathNavigator does exist in some shape or form, for example in a toolkit or a freeware library)?
2) If I do have to make modifications in the code, what would be the best way to go? Ideally, I would like to make minimal changes, not to rewrite 80% of the code just to be able to use something like XLinq.
To resume, in case I have to give up XPathNavigator, all I need is a way to bookmark places in my document and to get back to them so that I can continue to iterate from where I left off.
Thanks in advance for any help/ideas.
You are not missing something obvious, there is no implementation of XPathNavigator or XPathDocument in the Silverlight versions of the libraries.
The "best way to go" is highly subjective and would really depend on how many lines of code are really depending on XPathNavigator. However I see a couple of choices.
Go ahead and re-write the code using XDocument, XElement etc from the System.Xml.Linq namepsace. This may not be as bad a choice as you might think.
Wrap Xml-to-Linq objects in your own implementation of those properties and methods of the XPathNavigator that you are actually using. It shouldn't be too hard re-create most the features of the XPathNavigator against the Xml-to-Linq objects. You can then run your existing code against your own XPathNavigator.
XPath (xdoc.XPathSelectElements) is available in Silverlight 4: here's an online test tool.
There are tons of ways:

You can still use Linq to XML just minus the linq syntax and use the Linq Extension methods.
