• Check if XML node is empty

  - by Vinit

  I have a simple XML structure like <main> <node1><!-- comments --><!-- comments --></node1> </main> and this can have any number of sub-nodes or values like: <main> <node1><!-- comments --><!-- comments --><p>texttext text</p> more text <br/></node1> </main> I want to check if the node is empty or not: I'm doing something like: <xsl:if test="string-length(main/node1//text())&gt;0"> But it does not work as if there are multiple tags, then string-length function will break coz of multiple arguments. Any help to solve this issue is really appreciated.

• Arabic SQL query (on Oracle DB) returns empty result

  - by unprecedented

  I have this query (that runs on Oracle 10g database): SELECT ge.*, ge.concept AS glossarypivot FROM s_glossary_entries ge WHERE (ge.glossaryid = '161' OR ge.sourceglossaryid = '161') AND (ge.approved != 0 OR ge.userid = 361) AND concept = '?' ORDER BY ge.concept The query must display all words that begin with the arabic letter "?" but unfortunately, it returns empty result .. However, if I run the same query on the same database which runs on MYSQL, it works well and displays the correct result .. What should I do in order to get this query working the right way on oracle 10 database? P.S. the oracle database character set is : "AL32UTF8" thank you so much in advance

• DataSet XML export is empty

  - by Shaine

  I've got in-memory dataset with couple of tables that is populated in code. Data-bound grids on the gui show table contents without a problem. Then I try to export the dataset into XML: ds.WriteXml(fdSave.FileName, XmlWriteMode.WriteSchema); and get empty XML (with couple of lines regarding dataset names but without any tables) If I export table directly I've got all the data but dataset name is obviously wrong: ds.Fields.WriteXml(fdSave.FileName, XmlWriteMode.WriteSchema); What am I missing? Is there any reasonable way to write the whole dataset into file?

• Should default passwords always be empty?

  - by mafutrct

  I'm currently designing a system that requires an admin to log in using a password. For certain reasons, it is difficult to set this password during installation, but it can be changed later. My idea is this: If I leave the default password empty, it is so horridly insecure that every admin is going to fix this as soon as possible. If I were to use some kind of predefined password instead, admins may think "ah.. nobody would think I've got 'defaultpassword' as my password so it's not very important to change." So the basic thought is to make it so terrible that even the most lazy people are going to do something about it.

• read in bash on tab-delimited file without empty fields collapsing

  - by Charles Duffy

  I'm trying to read a multi-line tab-separated file in bash. The format is such that empty fields are expected. Unfortunately, the shell is collapsing together field separators which are next to each other, as so: # IFS=$'\t' # read one two three <<<$'one\t\tthree' # printf '<%s> ' "$one" "$two" "$three"; printf '\n' <one> <three> <> ...as opposed to the desired output of <one> <> <three>. Can this be resolved without resorting to a separate language (such as awk)?

• Empty Post with JQuery Ajax Post

  - by chandru

  Hi, I am getting a some unusual problem with JQuery ajax. I am using IIS to host my web application and I have http handler for which I have enabled only POST verb on it. Using JQuery ajax, I am posting data to this http handler, this is working fine in our development and testing environment and also most of the time on production environment as well. But sometimes we are getting empty post data on to the server. When we look into the csBytes on IISLog we found that it was very less compare to other success post requests. We are using JSON.js to convert the javascript object back to raw json string and latest jquery.1-3.js for posting to server. Anbody know why this is happening?

• MySQL SELECT WHERE returning empty with long numbers, although they are there

  - by brybam

  Alright, so basically the most simple query ever... I've done this a million times... SELECT * FROM purchased_items WHERE uid = '$uid' if $uid == 123 It works fine and returns all data in rows where uid is 123 if $uid == 351565051447743 It returns empty... I'm positive 351565051447743 is a possible uid in some rows, i literally copied and pasted it into the table. $uid is a string, and is being passed as a string. This is something i've done a million times, and i've never had this simple query not work. Any ideas why this is not working?

• Java: empty ArrayLists in a foor loop

  - by Patrick

  hi, I'm reusing the same ArrayList in a for loop, and I use for loop results = new ArrayList<Integer>(); experts = new ArrayList<Integer>(); output = new ArrayList<String>(); .... to create new ones. I guess this is wrong, because I'm allocating new memory. Is this correct ? If yes, how can I empty them ? Added: another example I'm creating new variables each time I call this method. Is this good practice ? I mean to create new precision, relevantFound.. etc ? Or should I declare them in my class, outside the method to not allocate more and more memory ? public static void computeMAP(ArrayList results, ArrayList experts) { //compute MAP double precision = 0; int relevantFound = 0; double sumprecision = 0; thanks

• php - How do I get rid of this strange "empty delimiter" message

  - by Steven

  I have some code that uses the stristr function to extract data I need. It works, in that it gives me the results I'm looking for. BUT (you knew there was a but), it gives me this error message for every iteration of the loop: Warning: stristr() [function.stristr]: Empty delimiter in ... line 55 Like I said, the code works apart from this error. Can anyone suggest how i could amend this code to get rid of the message? Thanks in advance $data = stristr("$text", "$key"); $result = string_limit_words($data,2); print "$result<BR>";

• MySQL: Return grouped fields where the group is not empty, effeciently

  - by Ryan Badour

  In one statement I'm trying to group rows of one table by joining to another table. I want to only get grouped rows where their grouped result is not empty. Ex. Items and Categories SELECT Category.id FROM Item, Category WHERE Category.id = Item.categoryId GROUP BY Category.id HAVING COUNT(Item.id) > 0 The above query gives me the results that I want but this is slow, since it has to count all the rows grouped by Category.id. What's a more effecient way? I was trying to do a Group By LIMIT to only retrieve one row per group. But my attempts failed horribly. Any idea how I can do this? Thanks

• Python: Check if all dictionaries in list are empty

  - by Brant

  I have a list of dictionaries. I need to check if all the dictionaries in that list are empty. I am looking for a simple statement that will do it in one line. Is there a single line way to do the following (not including the print)? l = [{},{},{}] # this list is generated elsewhere... all_empty = True for i in l: if i: all_empty = False print all_empty Somewhat new to python... I don't know if there is a shorthand built-in way to check this. Thanks in advance.

• JclLastExceptStackListToStrings produces an empty string list

  - by Max

  I've installed JCL into Delphi 2010. In the following code try raise Exception.Create('Error Message'); except on E: Exception do begin ResultStatus := JclLastExceptStackListToStrings(sl, True, True, True, True); end; end; Also I have this call in the initialization section: initialization JclStartExceptionTracking; ResultStatus is false and sl is empty. I have set options to generate map and .jdbg files. Other functions, like ProcByLevel work fine. Is there something else I need to do to make JclLastExceptStackListToStrings work?

  - by Imran Omar Bukhsh

  I use the following query: select * from A LEFT JOIN B on ( A.t_id != B.t_id) to get all the records in A that are not in B. The results are fine except when table B is completely empty, but then I do not get any records, even from table A. Later It wont work yet!

• Empty R environment becomes large file when saved

  - by user1052019

  I'm getting behaviour I don't understand when saving environments. The code below demonstrates the problem. I would have expected the two files (far-too-big.RData, and right-size.RData) to be the same size, and also very small because the environments they contain are empty. In fact, far-too-big.R ends up the same size as bigfile.RData. I get the same results using 2.14.1 and 2.15.2, both on WinXP 5.1 SP3. Can anyone explain why this is happening? Thanks. a <- matrix(runif(1000000, 0, 1), ncol=1000) save(a, file="c:/temp/bigfile.RData") test <- function() { load("c:/temp/bigfile.RData") test <- new.env() save(test, file="c:/temp/far-too-big.RData") test1 <- new.env(parent=globalenv()) save(test1, file="c:/temp/right-size.RData") } test()
