I have encountered this tag in an xml file :
<?dctm xml_app="ignore"?>
What does this tag mean / signify ?
Googling this value did not return results as to what it means.
The <?...?> syntax is an XML processing instruction:
Processing instructions (PIs) allow documents to contain instructions for applications.
In this case it appears to be an instruction for Documentum, a content management system. When the document in question is stored in this application, it can specify some details about how it is to be handled by the application.
If you are not using the application in question you can probably just ignore this instruction, although obviously this will depend on exactly what you are doing with the document.
Here it is Leave my XML file alone in Documentum : To disable XML validation on import add the processing instruction <”dctm xml_app=”ignore”"> to the xml file. This will halt the parsing algorithm.
The value Ignore tells the system not to process this document as an XML
document. You must include this instruction; if you leave it out, the system
will use the Default XML Application to process the document.

In short: I am trying to load a csv file but the program always overwrites the existing file as an empty new file.
Longer: I am pretty new to Fortran, so bear with me. I am trying to read data from a csv file into a fortran program. Now I didn't write the program and it is pretty big, so I can't post the whole thing here. The program consists of a whole bunch of .f90 files and everything is compiled using a makefile. Now since I am loading the gcc module before compiling, I am assuming that it is compiled using GNU Fortran, because it is part of gcc. (idk how to find out if that is correct)
The compiler returns an executable in a different directory. When I execute the program in that directory it apparently overwrites the existing .csv file with a new blank one, so the program only reads "End of File". I don't know why it always creates a new file, how do I stop it from doing so?
As a side note, the csv file I am trying to read simply consists of a single column of floats, e.g.
"0.01, 0.13, 0.041,..." etc.
The code that I inserted into a subroutine of one of the .f90 files is the following:
real*8, dimension(nz) :: Nsq
integer :: i
open(10, file='Nsq.csv')
do i=1,20
read(10, *) Nsq(i)
enddo
close(10)
I have also tried to write a small test program, essentially running the same code as above. That one works just fine and outputs the contents of the csv file without any issues. For that one I use gfortran to compile it.
I have no experience in Fortran at all, so I am completely stumped, why this happens. I know the chances are slim that you guys can help me with this, since I can't provide the whole source code. But maybe someone has an idea why this occurs. Maybe you know an alternate way of reading csv files?
Thanks for your time.
The open-statement in Fortran OPEN(connect-spec-list), has a lot of connection specifications which define how an external file should be managed (see. Fortran 2018 Standard sec 12.5.6).
When you open a file using the simplest form of the open-statement:
OPEN(unit=unitid,file="filename")
A lot of default assumptions are made such as: ACCESS="SEQUENTIAL", ASYNCHRONOUS="NO", BLANK="NULL", .... The most important ones, however, are ACTION and STATUS which define the purpose of the file. The action specification states if you want to use the file for reading, writing or both, while the status essentially defines if we work on an existing file or not, and what we should do with it (replace it, keep it, ...)
Both these specifications have a default compiler dependent state.
In the Intel compiler suit, the default is action="readwrite", status="unknown" (see here and here)
Intel defines the status="unknown" as :Indicates the file may or may not exist. If the file does not exist, a new file is created and its status changes to 'OLD'.
The Gnu compiler suit has a different take on this. The default action is defined by a set of rules which depend on its accessibility if the file exists (+rw,+r-w,-r+w) (see here). The behaviour for the default action="unknown" is not documented but seems to be REWRITE (see Default Status of "Unknown" in Open)
It is advised to use a proper method if you know what you want to do with the file:
OPEN(newunit=unitid, file="filename", action="read", status="old")
I am working on a project to process data and, depending upon the contents of the data, format it for use by another system. Some of the data provided are not of use to that other system and some of it is so sparsely populated that it would be of no use - is there a way, using Freemarker, to prevent the output of a file at all based upon the contents of the data? I have tried using <#if> statements, but if the checks do not pass, I simply get a blank file output.
This is not up to FreeMarker, but to the software that calls it. FreeMarker doesn't create files, it just writes the output to a Writer. That Writer is provided by the software that calls FreeMarker. So that could implements a logic where the file isn't created until something non-whitespace is written, or could expose a directive to FreeMarker that drops the output file.
I'm saving scraped data to a web app, and here's a sample param:
400\xB0F.
This is the 'degree' character from a website, but when I put that into my model I get the dreaded invalid byte sequence in UTF-8 error.
Since it's coming from the web I thought I might try some client side encoding, so javascript turns that into: 400%B0F. This can at least get saved by ActiveRecord with no issue, but Rails seems to be escaping it again on the way out so those entities aren't decoded by the browser, so my show method shows the entire encoded string.
Where should I be cleaning up my input data, and what methods might be the best to use for unpredictable input?
Thanks!
Years ago I had, and solved, this very same problem in builder. Take a look at the to_xs method: http://builder.rubyforge.org/classes/String.html#M000007
You can require builder, and use it directly (you might want to pass false to escaping or you will get entity escaped output). Either that, or simply steal and adapt the source.
Update: here is the original, standalone, library:
http://intertwingly.net/stories/2005/09/28/xchar.rb
Perhaps you can use a binary form (like for upload file) with enctype="multipart/form-data" in form tag. Like this, you can use this data as a binary data ?
It's depends perhaps of waht you do with this data.
URI.unescape was the trick, after I encoded it client-side
Anyone know a way to pass an argument to the XSLT when using an SSIS XML Task?
There seems to be no obvious way to do this, but there may be some clever workaround/hack?
EDIT: I'm currently looking into running an xpath update to insert param values...
EDIT: I got this working in the end by using a script task to insert the parameter value into the XSLT file. Hacky, I know, but it works. (And I have to work with VB.net, ugh!)
A quick search indicates that sending XSLT params is not possible in SSIS.
But, it also indicates that you could work with a variable as the XSLT source: Using XML Task (XSLT) with variables on social.msdn.microsoft.com (scroll down to Wenyang Hu's answer).
However, this looks like it would be a real pain in the a** to use.
Another idea would be to create a small XML file with a fixed name first (as part of the whole process) and store your parameter/config values there.
In your XSLT you could then load the file through the document('fixedname.xml') function and pull out the values you've just put there.
Using VS2005/2008 as a resource editor, one of the options in the Add Resource dialog is HTML: it appears to allow me to embed HTML file(s) into a resource (res) file. Does anyone know how to grab the HTML (as a string) from VB6 code? The LoadResData appears to be close to what I'm looking for but the problem is there isn't a HTML format defined in the table of formats (in that documentation link).
In Win32 C headers a resource format constant is defined called RT_HTML, it has the value 23. It should be possible to load the HTML resource type. Additionally you can verify the resource type number by looking at the built exe file with Resource Hacker. It lists the resource format types and resource IDs embedded in the file.
here is a good tutorial in c++ http://www.rohitab.com/discuss/index.php?showtopic=15281
you can probably adapt the code(usually function names are the same for win32 routines search on msdn.microsoft.com for documentation) or search the website for a VB example
