Example of using PROC METADATA to get group memberships for a specific user from metadata

Preparing for output

Output written to physical XML file to later convert to SAS data set

Encoding of XML file specified to prevent problems with strange characters

filename outgroups

"/sas/user/test/groups.xml"

encoding="utf-8";

Setting server connection arguments

SERVER, PORT, USER, PASSWORD and PROTOCOL all default to corresponding system options if not specified

USER and PASSWORD (encoded with PROC PWENCODE) set to user with more rights

proc metadata userid="sasadm" password="{sas001}bXkgcGFzc3dvcmQ="

Setting output arguments

Write output to file reference created earlier

Output XML to contain a full header

out=outgroups

header=full

XML-formatted method call (1)

Tell the metadata server to get objects

From which repository to get objects

Type of objects to get

Specify namespace

in='<GetMetadataObjects>

<Reposid>$METAREPOSITORY</Reposid>

<Type>Person</Type>

<NS>SAS</NS>

XML-formatted method call (2) Set flags so that metadata server performs the correct

actions:

• Fill a pre-specified template (flag OMI_TEMPLATE=4)

• Use an XMLSelect element to filter metadata (flag OMI_XMLSELECT=128)

• Get the metadata found (flag OMI_GET_METADATA=256)

• Use XMLSelect element case-sensitive (flag OMI_MATCH_CASE=512)

<Flags>900</Flags>

XML-formatted method call (3) Both template and XMLSelect element need to be

within <Options> tags

Only want person and group names returned

<Options>

<Templates>

<Person Name="">

<IdentityGroups />

</Person>

<IdentityGroup Name=""/>

</Templates>

XML-formatted method call (4)

Only return data for persons with a specific name

Close open tags to finalize XML-formatted method call

<XMLSelect search="@Name=''Person 1''"/>

</Options>

</GetMetadataObjects>'

Putting it all togetherproc metadata userid="sasadm"

password="{sas001}bXkgcGFzc3dvcmQ="

out=outgroups

header=full

in='<GetMetadataObjects>

<Reposid>$METAREPOSITORY</Reposid>

<Type>Person</Type>

<NS>SAS</NS>

<Flags>900</Flags>

<Options>

<Templates>

<Person Name="">

<IdentityGroups />

</Person>

<IdentityGroup Name=""/>

</Templates>

<XMLSelect search="@Name=''Person 1''"/>

</Options>

</GetMetadataObjects>';

run;
