XML shredding of multiple nested elements with same name with XPath












0















I'm shredding a large XML-document into a table, and facing some troubles with nested node-structures, where I am extracting the ID's from the document
Here's an example of the XML-structure (stylised):



<ROOT>

    <ENTITY>

        <UNIT>

            <ID>TEXT 1.0</ID>

        </UNIT>

        <ENTITY>

            <UNIT>

                <ID>TEXT 2.0</ID>

            </UNIT>

            <ENTITY>

                <UNIT>

                    <ID>TEXT 3.0</ID>

                </UNIT>

            </ENTITY>

            <ENTITY>

                <UNIT>

                    <ID>TEXT 3.1</ID>

                </UNIT>

                <ENTITY>

                    <UNIT>

                        <ID>TEXT 4.0</ID>

                    </UNIT>

                </ENTITY>

            </ENTITY>

        </ENTITY>

        <ENTITY>

            <UNIT>

                <ID>TEXT 2.1</ID>

            </UNIT>

            <ENTITY>

                <UNIT>

                    <ID>TEXT 3.2</ID>

                </UNIT>

            </ENTITY>

        </ENTITY>

    </ENTITY>

</ROOT>


As you can see, there are multiple nested nodes with the same names (eg. ENTITY and UNIT), but I only want the two first levels..



I've tried //UNIT/ID/text(), but I get ALL the descendants...



My idea was that if I could return the first two levels, I could make a mapping table that would link the top-level with it's direct child levels....



My wanted output would be like:



ID (string)     SubID Array(string)

TEXT 1.0        {TEXT 2.0,TEXT 2.1}

TEXT 2.0        {TEXT 3.0,TEXT 3.1}

TEXT 2.1        {TEXT 3.2}

TEXT 3.0        {null}

TEXT 3.1        {TEXT 4.0}

TEXT 4.0        {null}


If you the selected the 2. level ID you would get that levels direct child level id's etc. etc. as the nesting in theory could go on and on.

Run scheduled task as local user group (not BUILTIN)

0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
