I have xml data like this
<users>
<user email="email#email.com">
<password>pass</password>
..
</user>
</users>
I want to retrieve the user's record (xml format) filtering by email and password.
I have tried
for $user in doc("users")/user
[#email="'.$email.'"]
[password="'.$password.'"]
return $user
but I get errors.
Please, how can I retrieve that user's data in xml format so that I can use something like domdocument or simplexmlparser to get the respective nodes?
My reference was http://www.w3schools.com/xsl/xpath_syntax.asp
You would probably want to combine the constrains to one single constraint
for $user in doc("users")//user[#email="'.$email.'" and password="'.$password.'"] return $user
This could also be achieved in one go by:
doc("users")//user[#email="'.$email.'" and password="'.$password.'"]
HTH,

The most likely cause of the errors you report is that your query asked for user elements that appear as the outermost element of the users document and which satisfy some further constraints, thus:
doc("users")/user[...][...]
But the XML you show has users, not user, as the outermost element.
In the short run, using ...//user instead of .../user, as is done in prker's answer, will solve this problem. (His recommendation to use only a single predicate makes no sense and has nothing to do with whatever problems you had.) The problem can also be fixed by getting the path right: doc("users")/users/user...
In the long run, you should learn to understand what is happening in your XPath expressions. Here, doc("users") returns the document node at the root of the XML document you specify, and the next step, /user (short for /child::user) asks for an element node named user which is the child of the document node.
It worked with this
'for $user in doc("users")//user
where
$user/password = "'.$password.'" and
$user[#email="'.$email.'"]
return $user ';

Hi all Watson Developers!
I have a question, exposing that I need to know a bit more about context variables!
A user enters "Who owns the boat DUO ?" and my Dialog then uses the Intent "#owner_of_boatname" That works!
I then want to store the boatname in a variable $boatname, to pass it on to my webhook, as the value "$boatname".
If I create an entity with a list containing all possible boatnames, then it works, but what if I do not have all boatnames, and just want to pick up the $boatname from the user, and pass in on to the weebhook ? How do I fill out the handler then ?
I've tried to just put in "DUO" as value to my webhook, and that works fine, so the webhook itself works - I just need to be able to transfer variables to it!
How ?
Thanks a lot
Lars ;-) enter image description here
The ideal solution for this question should use A.I model created in Watson Knowledge Studio to identify names in user's text and deploy it to Natural Language Understanding instance which you would use the extract the name.
However, we can make a simpler solution, we must assume that the name of the boat will always be at the end of user's input and we can use a regular expression on Watson Assistant to extrat the name. You have to create a node before you pass to the webhook just to identify that user will pass the name of the boat, for example:
Assistant: What is the name of your boat?
User: The name of my boat is boatname
The node that return "What is the name of your boat?" should jump to a node and wait to user request and the condition of this node should always be true. When the user says "The name of my boat is boatname" the node with the condition always true should have context variable with the following regex expression in value context area:
"<? input.text.extract('\s\"?(\w+)\"?$',0) ?>"
This regex rule identify the last word of a phrase with double quotes or not.
Once you have extracted the boat's name you can make the node request you webhook.
Here we are using the SpeL language to access the assistant payload to extrat the last word of a phrase. You can find more information about functions on context variables here here.
i make one table for with some column with nullable.
i already tried with two different query. one using
Register_member::where('passport',$passport)->orWhere('adharcardnumber',$adharcardnumber)->get();
and second DB::table type query.
$row = Register_member::where('passport',$passport)->orWhere('adharcardnumber',$adharcardnumber)->get();
if (!empty($row))
{
return response()->json(["status"=>0, "message"=>"Adharcard or Paasport number already exit."]);
}
if (empty($row))
{
Register_member::insert(['first_name'=>request('first_name'), 'middle_name'=>request('middle_name'), 'last_name'=>request('last_name'), 'adharcardnumber'=>request('adharcardnumber'), 'ocipcinumber'=>request('ocipcinumber'), 'passport'=>request('passport'), 'birthday'=>request('birthday'),
'mobilecode'=>request('mobilecode'), 'mobilenumber'=>request('mobilenumber'), 'email'=>request('email'), 'address'=>request('address'), 'landmark'=>request('landmark'), 'area'=>request('area'),
'gender'=>request('gender'), 'pincode'=>request('pincode'), 'city_name'=>request('city_name'), 'state_id'=>request('state_id'), 'country_id'=>request('country_id'), 'sampraday'=>request('sampraday'), 'other'=>request('other'), 'sms'=>request('sms')]);
return response()->json(["status"=>1, "message"=>"Member register successful."]);
}
if adharcardnumber or passport number are exists in table, then nagetive response. if in both any one in unique then, insert data in table
Let me suggest you something which I think serve you as a good solution. You can use the unique with required and regex. In this way it will use the already recommended ways of Laravel which are the best.
As an example for your adhaar card,
the validation should look like this
$request->validate([
'adhaar ' =>['required','unique:users','regex:/\d{12}/'],
]);
where adhar is the filed name where adhaar number is entered. Be sure to use validator like this use Illuminate\Support\Facades\Validator;. Also $request is the instance of the Request.
Using the required prevent empty field submission and the regex will throw an error if the pattern is not matched completely. so I think it would be a better a way to handle the scenario.
the above solution will work in both adhaar and passport. But for the passport the regex will be different though.
Please note these are all demo examples, you might need to modify it according to your needs. I use https://www.phpliveregex.com/ for regex making and checking and it is good enough.
I hope you get an idea of how to begin but if you need more information then let me know in the comments.
So I have a case where I need to be able to work on the actual Hyperlink element inside the body of the docx, not just the target URL or the internal/externality of the link.
As a possible additional wrinkle this hyperlink wasn't present in the docx when it was opened but instead was added by the docx4j-xhtmlImporter.
I've iterated the list of relationships here: wordMLPackage.getMainDocumentPart().getRelationshipsPart().getRelationships().getRelationship()
And found the relationship ID of the hyperlink I want. I'm trying to use an XPath query: List<Object> results = wordMLPackage.getMainDocumentPart().getJAXBNodesViaXPath("//w:hyperlink[#r:id='rId11']", false);
But the list is empty. I also thought that it might need a refresh because I added the hyperlink at runtime so I tried with the refreshXMLFirst parameter set to true. On the off chance it wasn't a real node because it's an inner class of P, I also tried getJAXBAssociationsForXPath with the same parameters as above and that doesn't return anything.
Additionally, even XPath like "//w:hyperlink" fails to match anything.
I can see the hyperlinks in the XML if I unzip it after saving to a file, so I know the ID is right: <w:hyperlink r:id="rId11">
Is XPath the right way to find this? If it is, what am I doing wrong? If it's not, what should I be doing?
Thanks
XPathHyperlinkTest.java is a simple test case which works for me
You might be having problems because of JAXB, or possibly because of the specific way in which the binder is being set up in your case (do you start by opening an existing docx, or creating a new one?). Which docx4j version are you using?
Which JAXB implementation are you using? If its the Sun/Oracle implementation (the reference implementation, or the one included in their JDK/JRE), it might be this which is causing the problem, in which case you might try using MOXy instead.
An alternative to using XPath is to traverse the docx; see finders/ClassFinder.java
Try without namespace binding
List<Object> results = wordMLPackage.getMainDocumentPart().getJAXBNodesViaXPath("//*:hyperlink[#*:id='rId11']", false);
In v2 it was possible to make a call to /files with the query fileId in children to get a list of DriveFile objects that were parents of the supplied file.
Now, it seems to be required to make a call to /files/:fileId?fields=parents, then make a separate call to /files/:parentId for each returned parent, possibly turning one call into a dozen.
Is this correct, and if so why? This is a huge performance hit to our app, so hopefully there's an undocumented method.
The query "'fileId' in children'" doesn't publicly exist (not documented/supported) in v2 either and I don't recall it ever existing. What does exist in V2 is the Parents collection which effectively answers the same question. In v3, to get the parents of a file you just get the child and ask for the parents field.
As for whether or not that is a performance hit, I don't think it is in practice. The Parents resource in v2 was very light to begin with, and other than the ID the only useful field was the 'isRoot' property. That you can calculate yourself by calling files/root up front to get the ID of the root folder for that user (just once and save it, it won't change for that user.)
If you need to get more information about the parents than just the IDs and are worried about the # of calls you have to make, use batching to fetch them. If you just have one parent, no need to batch (it's just overhead.) If you find that a file has multiple parents, create a batch request. That'll be sent as a single HTTP request/response and is handled very efficiently on the back end.
Point is, if you just need IDs, it's no worse than before. It's one call to get the parents of a file.
If you need more than IDs, it's at most 2 HTTP requests (outside really bizarre edge cases like 1000+ parents which would exceed the batch size :)
In V3 it is possible to list all children of a parent as it's explained here: https://developers.google.com/drive/v3/web/search-parameters
Example call:
https://www.googleapis.com/drive/v3/files?q=parents in '0Byho0qAdzabmVl8xcDR1S0pNY3c' of course replace spaces with %20, this will list all the files in the folder which has id='0Byho0qAdzabmVl8xcDR1S0pNY3c'
you just need to mention like below:
var request = service.Files.List();
request.Q = "('root' in parents)";
var FileListOfParentOnly = request.Execute();
How do I tell the Zend_Form that I want an element (and it's ID-label, etc) to use another ID value instead of the element's name?
I have several forms in a page. Some of them have repeated names. So as Zend_Form creates elements' IDs using names I end up with multiple elements with the same ID, which makes my (X)HTML document invalid.
What is the best solution to fix this, given that I really have to stick with using the same element names (they are a hash common to all forms and using the Zend_Form Hash Element is really out of question)?
Zend_Form_Element has a method called setAttribs that takes an array. You may be able to do something like $element->setAttribs(array('id' => "some_id"));
or you can do $element->setAttrib('id', 'some_id');
Thanks, Chris Gutierrez.
However, as I said, I needed to get ride of the default decorator generated IDs like -label. Wiht the $element->setAttribs() it is not possible, however.
So based on http://framework.zend.com/issues/browse/ZF-7125 I just did the following:
$element->clearDecorators();
$element->setAttrib('id', 'some_id');
$element->addDecorator("ViewHelper");
Whoever sees this: please note this was enough for what I needed. But may not be for you (the default settings has more than the viewHelper decorator).
