domToWorkspace doesn't seem to do anything

[Seb Palmer]

Hello

Grateful for any help!  I am doing something wrong here, trying to load some xml into a workspace, hoping that the blocks will appear in place in the UI:

const xml = `<xml>

    <block type="start" id="1" deletable="false" x="30" y="30">

        <next>

            <block type="move_forwards" id="2">

                <next>

                    <block type="move_forwards" id="3"></block>

                </next>

            </block>

        </next>

    </block>

</xml>`;

var p = new DOMParser();

var blocks = p.parseFromString(xml, "application/xml");

var workspace = Blockly.mainWorkspace;

var result = Blockly.Xml.domToWorkspace(blocks, workspace);

// and result is just [], and nothing changes in the UI

I'm on a learning curve with Blockly, so it might be something simple but thanks for any help

Hello,

Thanks for your question :D It looks like you've got your XML set up correctly! But there may be other issues that I can't see from this code sample :/ Here are a few things I would check:

1) Is my workspace injected? (from your description it seems like yes, but still good to check!)

2) Are my "start" and "move_forward" blocks defined? You can check this in the browser console by doing `console.log(Blockly.Blocks)`

3) Are there any other errors in the browser console?

If you're able to share a link to your source code we may be able to take a look at that as well =) But hopefully that gives you some places to start!

Best wishes,

Hi Beka 

Thank you so much.  The issue turned out to be that the DOMParser().parseFromString returns something different than Blockly.Xml.textToDom

This works:

            const xml = `{solution}`;

            Blockly.Xml.clearWorkspaceAndLoadFromXml(Blockly.Xml.textToDom(xml), Blockly.mainWorkspace);

Sweet! I'm glad it's working for ya :D If you have any further questions always feel free to ask =)

Best of luck on your project!
