I need to use node.xpath to access a JSON node, but the property name contains space, like "First Name":
empDesc = cts.doc('/employee/employee1.json').xpath('//First Name');
How can I make this work?
Something like this:
empDesc = cts.doc('/employee/employee1.json').xpath('//*[name(.)="First Name"]')
But you are probably better off converting this to a JSON object and using normal access methods.
You can use node() with an argument inside MarkLogic XPath:
empDesc = cts.doc('/employee/employee1.json').xpath('//node("First Name")');
If you need to grab multiple properties, you could also convert to a JSON object first, and access that the regular way, like Mary suggested. Something like this:
let doc = cts.doc('/employee/employee1.json').toObject();
let empDesc = doc.employee['First Name'] + ' ' + doc.employee['Last Name'];
HTH!

I know that with Descriptive programming you can do something like this:
Browser("StackOverflow").Page("StackOverflow").Link("text:=Go To Next Page ", "html tag:=A").Click
But is it possible to create some kind of string so I can assign more than one data value and pass it as single variable? I've tried many combinations using escape characters and I always get error.
For example in the case above, let's say I have more properties in the Page object, so I'd normally have to do something like this:
Browser("StackOverflow").Page("name:=StackOverflow", "html id:=PageID")...etc...
But I'd like to pass "name:=StackOverflow", "html id:=PageID" as a single variable, so when writing many objects I'd only have to write:
Browser(BrowserString).Page(PageString).WebEdit("name:=asdfgh")
And the first part would remain static, so if the parents' data needs to be modified I'd only have to modify two variables and not all the objects created in all libraries.
Is it possible?
If I was not clear enough please let me know.
Thank you in advance!
I think what you're looking for is UFT's Description object
This allows you finer grained control on the description since in descriptive programming all values are regular expressions but with Description you can turn the regular expression functionality off for a specific property.
Set desc = Description.Create()
desc("html tag").Value = "A"
desc("innertext").Value = "More information..."
desc("innertext").RegularExpression = False
Browser("Example Domain").Navigate "www.example.com"
Browser("Example Domain").Page("Example Domain").WebElement(desc).Click
If you want to represent this with plain string then it's a bit more of a problem, you can write a helper function but I'm not sure I would recommend it.
Function Desc(descString)
Set ret = Description.Create()
values = Split(descString, "::")
For Each value In values
keyVal = Split(value, ":=")
ret(keyVal(0)).Value = keyVal(1)
Next
Set Desc = ret
End Function
' Usage
Browser("StackOverflow").Page("StackOverflow").WebElement(Desc("html tag:=H2::innertext:=some text")).Click
Further reading about descriptive programming.
As an alternative to Motti's excellent answer, you could also Set a variable to match your initial descriptive object and then extend it as required:
Set myPage = Browser("StackOverflow").Page("name:=StackOverflow", "html id:=PageID")
after which you can then use
myPage.WebEdit("name:=asdfgh")
throughout the rest of the code, so long as the myPage object stays in scope...
I have to provide the ref attribute value in an xf:select1. I need to select names of properties only if they are present in the supportedProperties instance which can be done with the following:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name
]/name">
However, the problem is that supportedProperties can contain names which are in capital letters. Assuming we cannot change the instance, is there a way we can do a case sensitive comparison?
Tried to use the lower-case() XPath function as follows but it didn't work:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name
]/lower-case(name)">
Assuming you are using XPath 2, you can write:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name/lower-case(.)
]/name">
What this does is that the lower-case(.) function applies to all elements in the sequence returned by instance('supportedProperties')/property/name.
You can also write it:
<xf:select1
ref="
instance('properties')/property[
name = (
for $name in instance('supportedProperties')/property/name
return lower-case($name)
)
]/name">
var divfoo=document.getElementById("foo");
divfoo.className=" css-class css-class2 ";
divfoo.className=divfoo.className.replace(" css-class2 ", "");
The above code works. but I would like to make changes to last line of above code which is using replace method. Instead of writing the code like above, I would like to know why doesn't it work when written like below.
var divfoo=document.getElementById("foo");
divfoo.className=" css-class css-class2 ";
divfoo.className.replace(" css-class2 ", "");
Why should one assign to "divfoo.className" when applying replace method to the same "divfoo.className", why can't we just apply method directly like above code did?
Because of this should I hate javascript for not being logical?
enter code here
Element.className is a plain string representation of class HTML attribute.
String.replace method does not change the source string that is called on, just returns the result of replacement procedure.
If you want more "logical / functional" approach, look at Element.classList interface, namely the remove method.
I have a text file (objects.txt) which contains Objects and its attributes.
The content of the file is something like:
Object.attribute = "data"
On a different file, I am Loading the objects.txt file and if I type:
puts object.attribute it prints out data
The issue comes when I am trying to access the object and/or the attribute with a string. What I am doing is:
var = "object" + "." + "access"
puts var
It prints out object.access and not the content of it "data".
I have already tried with instance_variable_get and it works, but I have to modify the object.txt and append an # at the beginning to make it an instance variable, but I cannot do this, because I am not the owner of the object.txt file.
As a workaround I can parse the object.txt file and get the data that I need but I don't want to do this, as I want take advantage of what is already there.
Any suggestions?
Yes, puts is correctly spitting out "object.access" because you are creating that string exactly.
In order to evaluate a string as if it were ruby code, you need to use eval()
eg:
var = "object" + "." + "access"
puts eval(var)
=> "data"
Be aware that doing this is quite dangerous if you are evaluating anything that potentially comes from another user.
I have a bunch of strings that look, for example, like this:
<option value="Spain">Spain</option>
And I want to extract the name of the country from inside.
The easiest way I could think of to do this in Ruby was to use a regular expression of this form:
country = line.match(/>(.+)</)
However, this returns >Spain<. So I did this:
line.match(/>(.+)</).to_s.gsub!(/<|>/,"")
Works well enough, but I'd be surprised if there's not a more elegant way to do this? It seems like using a regular expression to declare how to find the thing you want, without actually wanting the enclosing strings that were used to match it to be part of the data that gets returned.
Is there a conventional approach to this problem?
The right way to deal with that string is to use an HTML parser, for example:
country = Nokogiri::HTML('<option value="Spain">Spain</option>').at('option').text
And if you have several such strings, paste them together and use search:
html = '<option value="Spain">Spain</option><option value="Canada">Canada</option>'
countries = Nokogiri::HTML(html).search('option').map(&:text)
# ["Spain", "Canada"]
But if you must use a regex, then:
country = '<option value="Spain">Spain</option>'.match('>([^<]+)<')[1]
Keep in mind that match actually returns a MatchData object and MatchData#to_s:
Returns the entire matched string.
But you can access the captured groups using MatchData#[]. And if you don't like counting, you could use a named capture group as well:
country = '<option value="Spain">Spain</option>'.match('>(?<name>[^<]+)<')['name']
