How to access the package by name - enterprise-architect

Question

We have the model which contains packages and sub packages.So how can we move the pointer to the specific package by the package name.So is there any way to iterate through the model and get the package by name

Answer 1

Use
Repositore.SQLQuery("SELECT package_id FROM t_package WHERE name=<theName>")
That will return a XML result set containing all packages with the name you are looking for. It might look like this:
<?xml version="1.0"?>
<EADATA version="1.0" exporter="Enterprise Architect">
<Dataset_0><Data><Row><package_id>1</package_id></Row><Row><package_id>2</package_id></Row><Row><package_id>3</package_id></Row></Data></Dataset_0></EADATA>
So you can either stuff that in a XML parser or use a regular expression like
/package_id>(\d+)/
to filter all the package-ids.
In turn simply use
Repository.GetPackageById(<found id>)
to access the found package(s).

Answer 2

As pointed out in the comment, this will work:
List<EA.Package> myPacks = new List<EA.Package>();
public void GOThroughAllPackages(EA.Package dumpPackage)
{
foreach (EA.Package packages in dumpPackage.Packages)
{
if(packages.Name.ToLower().Equals(requiredPackName))
{
myPacks.Add(packages);
break;
}
GOThroughAllPackages(packages);
}
}

Answer 3

Alternate solution (C#) that doesn't require parsing an xml string:
List<EA.Package> packages = new List<EA.Package>();
string searchValue = "somePackageName";
var packageElements = Repository.GetElementSet("select o.Object_ID from t_object o inner join t_package p on p.ea_guid = o.ea_guid where o.Name = '"+searchValue+"'",2);
foreach (EA.Element packageElement in packageElements)
{
packages.Add(Repository.GetPackageByGuid(packageElement.ElementGUID);)
}
It uses the Repository.GetElementSet() with parameter 2 that tells it to accept an SQL query.
Note that this solution will not return root packages as they don't have an t_object counterpart.
