How can I create this XML structure?
I know how to add the “COLUMN” to <TABLE_DATA> but not, I make “COLUMN” as part of “HEADERS” and make “HEADERS” as part of <TABLE_DATA>.

How/where are you using XML in your code? Are you using juce::XmlElement or juce::ValueTree?

In general, you’ll want to create the HEADERS node first, add each of the COLUMN nodes, then add that HEADER node to the TABLE_DATA node.

The main difference which one to choose is, if you need text nodes. That is content between an opening tag and a closing tag, like you know from html: <a href="foo">Some text</a>.
That feature is not available using ValueTree. In that case you need to use the juce::XmlElement and related classes.

The example you posted can be easily coded with juce::ValueTree and thanks to the initialisers even in one statement:

auto tree = juce::ValueTree ("TABLE_DATA", {},
    {"HEADERS", {},
        {"COLUMN", {{"columnId", "1"},
                    {"name", "ID"},
                    {"width", 50}}},
        {"COLUMN", {{"columnId", "2"},
                    {"name", "Module"},
                    {"width", 200}}},
// ...
    {"DATA", {},
        {"ITEM", {{"ID", 01},
                  {"Module", "juce_analytics"},
                  {"Name", "JUCE analytics classes"},
                  {"Version", "5.2.0"},
// ...

Basically the juce::ValueTree takes three arguments: typename, properties as list of tuples and children again as initialiser list.

Didn’t count the closing brackets…

And using variables as identifiers/property names is strongly recommended, other than I did in the example

I use juce::XmlElement and also know how to add ChildElements to an XmlElement.

But don’t know how I add the HEADER node to the TABLE_DATA node after adding colums to the HEADER node.

I will just try it with ValueTree.

If you understand the adding of child elements, you should have been able to sort out what you wanted… But we can help get you on the right path if you share some code - what have you tried?

Ok, I have now figured out myself what my mistake was.
Thanks for the help.

This is how it works now

// create an outer node called "PLUGIN_TABLE_TEMP_DATA"
juce::XmlElement pluginTableTempData("PLUGIN_TABLE_TEMP_DATA");

//juce::XmlElement pluginTableTempData_headers("HEADERS");
juce::XmlElement* pluginTableTempData_headers = new juce::XmlElement("HEADERS");

for (int i = 0; i < 10; ++i)
juce::XmlElement* pluginTableTempData_columnid = new juce::XmlElement("COLUMN");

// create the inner elements.
for (int j = 1; j < TableHeaderNammes.size() + 1; j++)
    pluginTableTempData_columnid->setAttribute("columnId", j);
    pluginTableTempData_columnid->setAttribute("width", "50");

// ..and add our new elements to the parent node

// add the parent node to the main node

Thanks for your help

Note that you could use createNewChildElement.
