Support the NewValue processing instruction

Aspose.Diagram Product Family

Hi

We are directly updating .vsdx XML files to update shape data and then using Aspose.Diagram to convert the .vsdx to .svg.

Presently, we use a NewValue processing instruction (https://msdn.microsoft.com/en-us/library/office/jj649391.aspx#sectionToggle5) to ensure Visio picks up the change and displays the new value for the data.

e.g.

<Cell N="Value" V="New string value" U="STR" F="Inh">
  <?NewValue V?>
</Cell>

While this works for Visio, Diagram doesn’t pick up on the processing instruction and use the updated text.

Is it possible to have Diagram respect these processing instructions, or is it possible to force an update of shape data?

Using Aspose.Diagram 18.1 for Java

Thanks
Vittal

@vittala,

The Shape class offers refreshData() method which you can call before exporting VSDX drawing to SVG format. Kindly send us your VSDX drawings with and without XML updates. We will investigate and share our findings with you.

Hi Imran

Attached is an example showing a rectangle with a shape data field of “CogniDox_Partnum” set. In the original version this is “TOBECHANGED”, in the modified version, it’s “AA-000830-AW”. In the XML, we’ve updated the property value in shape ID 2, and the text call-out ValueText in shape ID 3, putting in the NewValue processing instruction. Opening the modified file in Visio updates the value in the call-out. However, saving as SVG with Diagram keeps the “TOBECHANGED” text.

Iterating through all the shapes and calling refreshData on all the shapes throws exceptions for shapes 1 and 2, and is OK for shapes 3 and 4. However, it has no effect on the SVG output.
