This is my xml string
string fromHeader= "<a:From><a:Address>http://ex1.example.org/</a:Address></a:From>";
I want to load it into an XElement, but doing XElement.Parse(fromHeader) gives me an error due to the 'a' prefixes. I tried the following:
XNamespace xNSa = "http://www.w3.org/2005/08/addressing";
string dummyRoot = "<root xmlns:a=\"{0}\">{1}</root>";
var fromXmlStr = string.Format(dummyRoot, xNSa, fromHeader);
XElement xFrom = XElement.Parse(fromXmlStr).Elements().First();
which works, but seriously, do i need 4 lines of code to do this! What is a quickest / shortest way of getting my XElement?
I found out the above 4 lines are equivalent to
XNamespace xNSa = "http://www.w3.org/2005/08/addressing";
XElement xFrom = new XElement(xNSa + "From", new XElement(xNSa + "Address", "http://ex1.example.org/"));
OR ALTERNATIVELY move the NS into the 'From' element before parsing.
var fromStr = "<a:From xmlns:a=\"http://www.w3.org/2005/08/addressing\"><a:Address>http://ex1.example.org/</a:Address></a:From>";
XElement xFrom = XElement.Parse(fromStr);

The title may be a bit confusing but basically this is the problem: I am using Jena and a Pellet reasoner to produce property literals from a resource called Patient_Doug. The triple looks like this:
Patient_Doug-> hasSuggestion-> Literal inferred suggestion.
The problem is that the Protege Pellet reasoner comes up with three suggestions for Doug, because Doug is in a pretty bad way in hospital. The Protege reasoner suggests that Doug needs a Hi-Lo bed, an RF ID band and a bed closer to the nurse's station. Unfortunatly, in Jena, I can only get Hi-lo bed to print. Only one of 3 literals.
Here is some of the code.
OntModel model = ModelFactory.createOntologyModel( PelletReasonerFactory.THE_SPEC );
String ns = "http://altervista.org/owl/unit.owl#";
String inputFile = "c:\\jena\\acuity.owl";
InputStream in = FileManager.get().open(inputFile);
if (in == null) {
throw new IllegalArgumentException("File: " + inputFile + " not found");
}
model.read(in,"");
model.prepare();
//inf and reasoner wont run unless i use hp libraries!
//asserted data properties
Individual ind = model.getIndividual(ns+"Patient_Doug");
OntProperty abcValue = model.getOntProperty("http://example.org/hasABCValue");
//inferred data properties
OntProperty suggestion = model.getOntProperty(ns+"hasSuggestion");
//print asserted data properties
System.out.println("Properties for patient "+ind.getLocalName().toString());
System.out.println( abcValue.getLocalName()+"= "+ind.getPropertyValue(abcValue).asLiteral().getInt());
//print inferenced data properties
StmtIterator it = ind.listProperties(suggestion);
//this iterator only prints one suggestion in an infinite loop
while (it.hasNext()) {
System.out.println("A posible suggestion= "+ind.getPropertyValue(suggestion).asLiteral().getString());
}
}
The code works fine but the iterator at the end only prints only one subggestion in an infinite loop.
I would be grateful for any suggestions.
Thanks.
This code works to iterate and print the many inferred hasSuggestions. The hasSuggestion SWRL rules are in the OWL ontology
OntModel model = ModelFactory.createOntologyModel( PelletReasonerFactory.THE_SPEC );
String ns = "http://altervista.org/owl/unit.owl#";
String inputFile = "c:\\jena\\acuity.owl";
InputStream in = FileManager.get().open(inputFile);
if (in == null) {
throw new IllegalArgumentException("File: " + inputFile + " not found");
}
model.read(in,"");
model.prepare();
//inf and reasoner wont run unless i use hp libraries!
//asserted data properties
Individual ind = model.getIndividual(ns+"Patient_Doug");
OntProperty abcValue = model.getOntProperty("http://example.org/hasABCValue");
//inferred data properties
OntProperty suggestion = model.getOntProperty(ns+"hasSuggestion");
//print asserted data properties
System.out.println("Properties for patient "+ind.getLocalName().toString());
System.out.println( abcValue.getLocalName()+"= "+ind.getPropertyValue(abcValue).asLiteral().getInt());
for (StmtIterator j = ind.listProperties(suggestion); j.hasNext(); ) {
Statement s = j.next();
//System.out.println( " " + s.getPredicate().getLocalName() + " -> " );
System.out.println( "A possible suggestion... " + s.getLiteral().getLexicalForm());
}

As this is applicable to both Genie and Vala, I thought it would be better suited as a stand-alone question.
The conceptual question is:
How does string interpolation work in Vala and Genie?
There are two options for string interpolation in Vala and Genie:
printf-style functions:
var name = "Jens Mühlenhoff";
var s = string.printf ("My name is %s, 2 + 2 is %d", name, 2 + 2);
This works using varargs, you have to pass multiple arguments with the correct types to the varargs function (in this case string.printf).
string templates:
var name = "Jens Mühlenhoff";
var s = #"My name is $name, 2 + 2 is $(2 + 2)";
This works using "compiler magic".
A template string starts with #" (rather then " which starts a normal string).
Expressions in the template string start with $ and are enclosed with (). The brackets are unneccesary when the expression doesn't contain white space like $name in the above example.
Expressions are evaluated before they are put into the string that results from the string template. For expressions that aren't of type string the compiler tries to call .to_string (), so you don't have to explicitly call it. In the $(2 + 2) example the expression 2 + 2 is evaluated to 4 and then 4.to_string () is called with will result in "4" which can then be put into the string template.
PS: I'm using Vala syntax here, just remove the ;s to convert to Genie.

Now I have a corresponding SQL Server table, where I can easily load the data as destination.
Since I am new to SSIS, having trouble as to how to write the Script Component so that I can filter the Source Text files and easily load into sql server table.
Thanks in advance!
There are a few ways to do it. If the format of the files are constant, there are some useful properties of the flat file connection manager editor. For example, you can add a new flat file connection into the connection managers. There are some properties such as "Rows to skip" for the above file, you could set this to 18. Then it would start at the columns line with the "|".
Another property of the flat file connection manager that may be useful is that if you open the flat file connection manager, and then click on columns in the side menu, you can set the column delimter to the pipe "|"
But if the format of the file will change, e.g. variable number of header rows, you can use a script task to remove any non-piped rows. e.g. the header and footer.
For example, you can add a method such as file.readalllines and then edit or remove the lines as needed then save the file.
Info about that method is here:
https://msdn.microsoft.com/en-us/library/s2tte0y1%28v=vs.110%29.aspx
e.g. to remove last line in script task
string[] lines = File.ReadAllLines( "input.txt" );
StringBuilder sb = new StringBuilder();
int count = lines.Length - 1; // all except last line
for (int i = 0; i < count; i++)
{
sb.AppendLine(lines[i]);
}
File.WriteAllText("output.txt", sb.ToString());

Is there a way to convert or create a new [[bracket style string]] based on an existing 'quote style string'?
s = "one\ntwo" -- how the string was created
s2 = [[one\ntwo]] -- what i want the new string to be
Escaping the escape sequence seems to achieve the desired effect, at least in this case.
s2 = string.gsub(s, "\n", "\\n")
> print(s2)
one\ntwo
One way is to make a table that has all the possible escape sequences:
local t = {["\a"] = [[\a]],
["\b"] = [[\b]],
["\f"] = [[\f]],
["\n"] = [[\n]],
["\r"] = [[\r]],
["\t"] = [[\t]],
["\r"] = [[\r]],
["\\"] = [[\\]],
["\""] = [["]],
["\'"] = [[']],
}
local s2 = s:gsub(".", t)
This one has kept me stumped for a couple of days now.
It's my first dabble with CLR & UDF ...
I have created a user defined function that takes a multiline String as input, scans it and replaces a certain line in the string with an alternative if found. If it is not found, it simply appends the desired line at the end. (See code)
The problem, it seems, comes when the final String (or Stringbuilder) is converted to an SqlString or SqlChars. The converted, returned String always contains the Nul character as every second character (viewing via console output, they are displayed as spaces).
I'm probably missing something fundamental on UDF and/or CLR.
Please Help!!
Code (I leave in the commented Stringbuilder which was my initial attempt... changed to normal String in a desperate attempt to find the issue):
[Microsoft.SqlServer.Server.SqlFunction]
[return: SqlFacet(MaxSize = -1, IsFixedLength = false)]
//public static SqlString udf_OmaChangeJob(String omaIn, SqlInt32 jobNumber) {
public static SqlChars udf_OmaChangeJob(String omaIn, SqlInt32 jobNumber) {
if (omaIn == null || omaIn.ToString().Length <= 0) return new SqlChars("");
String[] lines = Regex.Split(omaIn.ToString(), "\r\n");
Regex JobTag = new Regex(#"^JOB=.+$");
//StringBuilder buffer = new StringBuilder();
String buffer = String.Empty;
bool matched = false;
foreach (var line in lines) {
if (!JobTag.IsMatch(line))
//buffer.AppendLine(line);
buffer += line + "\r\n";
else {
//buffer.AppendLine("JOB=" + jobNumber);
buffer += ("JOB=" + jobNumber + "\r\n");
matched = true;
}
}
if (!matched) //buffer.AppendLine("JOB=" + jobNumber);
buffer += ("JOB=" + jobNumber) + "\r\n";
//return new SqlString(buffer.ToString().Replace("\0",String.Empty)) + "blablabla";
// buffer = buffer.Replace("\0", "|");
return new SqlChars(buffer + "\r\nTheEnd");
}
I know in my experiences, the omaIn parameter should be of type SqlString and when you go to collect its value/process it, set a local variable:
string omaString = omaIn != SqlString.Null ? omaIn.Value : string.empty;
Then when you return on any code path, to rewrap the string in C#, you'd need to set
return omaString == string.empty ? new SqlString.Null : new SqlString(omaString);
I have had some fun wrestling matches learning the intricate hand-off between local and outbound types, especially with CLR TVFs.
Hope that can help!
