I have a HTML element from a HTTP request like so:
<input type="radio" data-trip="0" id="fareRadioId_" name="pricefare" value="H15CNGE~SHATSA~220420150955~3332|H15CNGE~TSASHA~270420150715~338" class="pricefare" data-toggle="radio" checked="checked">
I'm used to pulling a value from a CSS select like so:
.check(css("input#fareRadioId_0.select_departure", "value").saveAs("departSellKey"))
But after I've selected the value in the element above which is "H15CNGE~SHATSA~220420150955~3332|H15CNGE~TSASHA~270420150715~338", I want to split it in to parts, with the split character being "|", and save the two parts in to session with 2 different names. Is this possible?
I've pretty new to Gatling and Scala so this is a little above my head at the moment. Any help would be greatly appreciated.
I'm not sure if you'll be able to save the two parts with different names, but it's fairly easy to perform the split and store the result as a Seq, after which you can access it with indexes etc.
What you need to do is insert a suitable transformer into your check:
.check(css("...").transform(_.split('|').toSeq).saveAs("sellKeys"))
This takes the String from the css() expression, does a split() on it (which creates an Array[String]) and then converts it to a Seq because they're nicer to work with :-)
The Seq is then saved into sellKeys, so later on you can do things like (silly example):
.exec( session => {
val keys = session("sellKeys").as[Seq[String]]
println(s"keys are ${keys.mkString(" and ")}")
println(s"the first key is ${keys.head}")
session
}
)
Output:
keys are H15CNGE~SHATSA~220420150955~3332 and H15CNGE~TSASHA~270420150715~338
the first key is H15CNGE~SHATSA~220420150955~3332

In my ML db, we have documents with distributor code like 'DIST:5012' (DIST:XXXX) XXXX is a four-digit number.
currently, in my TDE, the below code works well.
However instead of concat all the raw distributor codes, I want to simply concat the number part only. I used the fn:substring-after XQuery function. However, it won't work. It won't show that distributorCode column in the SQL View anymore. (Below code does not work.)
What is wrong? How to fix that?
Both fn:substring-after and fn:string-join is in TDE Dialect page.
https://docs.marklogic.com/9.0/guide/app-dev/TDE#id_99178
substring-after() expects a single string as input, not a sequence of strings.
To demonstrate, this will not work:
let $dist := ("DIST:5012", "DIST:5013")
return substring-after($dist, "DIST:")
This will:
for $dist in ("DIST:5012", "DIST:5013")
return substring-after($dist, "DIST:")
I need to double check what XPath expressions will work in a DTE, you might be able to change it to apply the substring-after() function in the last step:
fn:string-join( distributors/distributor/urn/substring-after(., 'DIST:'), ';')
i am not a dot net programmer but need to migrate dotnet code to java .having issue understanding this follwing piece
Lets say specificTermical and ShipTo have latitutde property with different value so what happends when we use concat what will be the final value eg. 23.10+43.10 or something else
List<OrderDispatchItemDTO> locations =(List<OrderDispatchItemDTO>) msg.Details.Select(x => x.SpecificTerminal).Concat(msg.Details.Select(x => x.ShipTo));
The line of code that you provide returns a List of OrderDispatchItemDTO objects, that contains the values of both the SpecificTerminal and ShipTo properties of the Details objects.
It doesn't make any kind of calculation between the values of SpecificTerminal and ShipTo properties; it only adds both of them in a common list.
More detailed:
The Select method returns a new IEnumerable of the selected objects
And the Concat method concatenates the second collection into the first.
Concat is a string method. When you concatenate "23.10" and "43.10", it gives "23.1043.10". Therefore combining the two strings together.
To do any calculation in c#, you have to convert from strings data types to other mathematical data type that fits the say.
You may convert those two values to float and add them as shown below:
Float sum = Convert.ToFloat(23.10) + Convert.ToFloat(43.10);
I have the data as below manner.
<Status>Active Leave Terminated</Status>
<date>05/06/2014 09/10/2014 01/10/2015</date>
I want to get the data as in the below manner.
<status>Active</Status>
<date>05/06/2014</date>
<status>Leave</Status>
<date>09/10/2014</date>
<status>Terminated</Status>
<date>01/10/2015</date>
please help me on the query, to retrieve the data as specified above.
Well, you have a string and want to split it at the whitestapces. That's what tokenize() is for and \s is a whitespace. To get the corresponding date you can get the current position in the for loop using at. Together it looks something like this (note that I assume that the input data is the current context item):
let $dates := tokenize(date, "\s+")
for $status at $pos in tokenize(Status, "\s+")
return (
<status>{$status}</status>,
<date>{$dates[$pos]}</date>
)
You did not indicate whether your data is on the file system or already loaded into MarkLogic. It's also not clear if this is something you need to do once on a small set of data or on an on-going basis with a lot of data.
If it's on the file system, you can transform it as it is being loaded. For instance, MarkLogic Content Pump can apply a transformation during load.
If you have already loaded the content and you want to transform it in place, you can use Corb2.
If you have a small amount of data, then you can just loop across it using Query Console.
Regardless of how you apply the transformation code, dirkk's answer shows how you need to change it. If you are updating content already in your database, you'll xdmp:node-delete() the original Status and date elements and xdmp:node-insert-child() the new ones.
I'm attempting to scrape a page that has about 10 columns using Ruby and Nokogiri, with most of the columns being pretty straightforward by having unique class names. However, some of them have class ids that seem to have long number strings appended to what would be the standard class name.
For example, gametimes are all picked up with .eventLine-time, team names with .team-name, but this particular one has, for example:
<div class="eventLine-book-value" id="eventLineOpener-118079-19-1522-1">-3 -120</div>
.eventLine-book-value is not specific to this column, so it's not useful. The 13 digits are different for every game, and trying something like:
def nodes_by_selector(filename,selector)
file = open(filename)
doc = Nokogiri::HTML(file)
doc.css(^selector)
end
Has left me with errors. I've seen ^ and ~ be used in other languages, but I'm new to this and I have tried searching for ways to pick up all data under id=eventLineOpener-XXXX to no avail.
To pick up all data under id=eventLineOpener-XXXX, you need to pass 'div[id*=eventLineOpener]' as the selector:
def nodes_by_selector(filename,selector)
file = open(filename)
doc = Nokogiri::HTML(file)
doc.css(selector) #doc.css('div[id*=eventLineOpener]')
end
The above method will return you an array of Nokogiri::XML::Element objects having id=eventLineOpener-XXXX.
Further, to extract the content of each of these Nokogiri::XML::Element objects, you need to iterate over each of these objects and use the text method on those objects. For example:
doc.css('div[id*=eventLineOpener]')[0].text
I'm having trouble working with a data table in R. This is probably something really simple but I can't find the solution anywhere.
Here is what I have:
Let's say t is the data table
colNames <- names(t)
for (col in colNames) {
print (t$col)
}
When I do this, it prints NULL. However, if I do it manually, it works fine -- say a column name is "sample". If I type t$"sample" into the R prompt, it works fine. What am I doing wrong here?
You need t[[col]]; t$col does an odd form of evaluation.
edit: incorporating #joran's explanation:
t$col tries to find an element literally named 'col' in list t, not what you happen to have stored as a value in a variable named col.
$ is convenient for interactive use, because it is shorter and one can skip quotation marks (i.e. t$foo vs. t[["foo"]]. It also does partial matching, which is very convenient but can under unusual circumstances be dangerous or confusing: i.e. if a list contains an element foolicious, then t$foo will retrieve it. For this reason it is not generally recommended for programming.
[[ can take either a literal string ("foo") or a string stored in a variable (col), and does not do partial matching. It is generally recommended for programming (although there's no harm in using it interactively).
