[1.6 UI] [Warning] XML parser: not well-formed (invalid token) at line 1

Hi @REDACTEDUSER

This error I get during Run-time loading via Canvas/LoadIntoEntity FN (here I load one canvas into another - 2x LoadIntoEntity).

The first lines are:

<ObjectStream version="1"> <Class name="AZ::Entity" version="2" type="{75651658-8663-478D-9090-2432DFCAFA44}"> <Class name="EntityId" field="Id" version="1" type="{6383F1D3-BB27-4E6B-A49A-6409B2059EAA}"> <Class name="AZ::u64" field="id" value="16546804917438919487" type="{D6597933-47CD-4FC8-B911-63F3E2B0993A}"/> </Class> <Class name="AZStd::string" field="Name" value="UiCanvasEntity" type="{EF8FF807-DDEE-4EB0-B678-4CA3A2C490A4}"/> <Class name="bool" field="IsDependencyReady" value="true" type="{A0CA880C-AFE4-43CB-926C-59AC48496112}"/> <Class name="AZStd::vector" field="Components" type="{2BADE35A-6F1B-4698-B2BC-3373D010020C}"> <Class name="UiCanvasComponent" field="element" version="1" type="{50B8CF6C-B19A-4D86-AFE9-96EFB820D422}"> <Class name="AZ::Component" field="BaseClass1" type="{EDFCB2CF-F75D-43BE-B26B-F35821B29247}"> <Class name="AZ::u64" field="Id" value="6261678898352291036" type="{D6597933-47CD-4FC8-B911-63F3E2B0993A}"/> </Class>

and:

Thank you for your investigation :)

Hi @chase,

Thank you for so clarity answer. You found a problem: I use '<' and '>' chars in my text.

Hi @jasiuj - if your UI canvas is loading correctly (that is, you're not seeing any issues/bugs with it other than the XML warning), then its possible that you're seeing a bug related to our Text Styling Markup feature:

http://docs.aws.amazon.com/lumberyard/latest/userguide/ui-editor-components-visual.html#ui-editor-component-text-styling-markup

The feature allows you to style text (on a text component) using a basic markup language (reminiscent of HTML). We use an XML parser to parse the string every time the string contents are loaded (or are changed), so if your canvas has a text component that contains reserved XML characters ('<', '>', '&'), and the text doesn't form a (somewhat) properly formatted XML string, the XML parser will log a warning that the string couldn't be parsed.

If that's the issue, then you can happily ignore the warning. We have a bug written up to suppress those warning messages to avoid unnecessary concern.

To verify if that's what is causing the issue:

1. Check the canvas that's causing the warning to see if you have any text components that contain reserved XML characters ('<', '>', '&').
2. Or, you can create a copy of the canvas, and remove any elements with text components on the canvas and verify whether the error still occurs. Again, if you're not noticing any problems (other than the warning itself), you can probably just ignore it and we should have the issue resolved eventually in an upcoming release.

Thanks for bringing this to our attention!
