Mathml visualization in webapp 18.1

[aleh.haidash]

Hello.
I see some differences between Oxygen Standalone Editor 18.0 and Oxygen Standalone Editor 18.1 (and webapp 18.1 too) in mathml formulas visualization. Oxygen can't display inner formulas, like this

Code: Select all

 <mml:math class="+ topic/foreign math-d/math ">

                    <mml:semantics>

                        <mml:mrow>

                            <mml:mrow>

                                <mml:mi mathvariant="italic">score</mml:mi>

                                <mml:mo>=</mml:mo>

                                <mml:mrow>

                                    <mml:mfrac>

                                        <mml:mrow>

                                            <mml:mi mathvariant="italic">rule_weight</mml:mi>

                                        </mml:mrow>

                                                  <mml:msub>

                                                  <mml:msub>

                                                  <mml:mi mathvariant="italic">similarity</mml:mi>

                                                  <mml:mi>i</mml:mi>

                                                  </mml:msub>

                                                </mml:mrow>

                                            </mml:mrow>

                                        </mml:mrow>

                                    </mml:mrow>

                                </mml:mrow>

                            </mml:mrow>

                        </mml:mrow>

                        <mml:annotation encoding="StarMath 5.0">score = {1} over {n} * rule_weight *

                            sum { weight_i * similarity_i } </mml:annotation>

                    </mml:semantics>

                </mml:math>

This functionality work good in prev. version of Standalone Editor ( for example in 18.0), but I didn't try it in prev version of webapp.

Details of error message in Standalone Editor:

Cannot display image
Cannot render the MathML equation using JEuclid: The prefix "mml" for element "mml:math" is not bound.

But resolving formulas from href links works fine.
How can I fix it for inner formulas in webapp?

Hello,

It looks like you forgot to declare the mml namespace.

Code: Select all

<mml:math class="+ topic/foreign math-d/math "> 

should be

Code: Select all

<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" class="+ topic/foreign math-d/math ">

Thank you, Gabriel.

Yes,this helped fix the problem in Oxygen Standalone Editor 18.1. But in Webapp the problem still remained, see screens

Hello Aleh,

I could not reproduce this issue, can you send a sample file where this bug can be reproduced to support@oxygenxml.com?
If rewriting the xml content is an option, you can try to replace the 'mml' namespace with 'm'. This might fix the issue in Web Author.

Best,
Gabriel

I sent an email. Please, keep me in touch.

Hello,

Still no luck, it works for me.
Here are the steps I took to reproduce the issue:
- Generated a sample project using the oxygen-sdk archetype [1][2]
- Built the oxygen-sample-webapp module [3]
- Modified the dita framework to include your custom catalog
- Put the generated war into tomcat and ran it

I could use some additional information:
- What is rendered inside the math-ml element? [4]
- Are there any errors shown in the browser console?
- Do you see any difference if you modify the math-ml plugin [a] to delete lines 36 an 37 of the JEuclidRenderer class and rebuild the sample webapp module [c]?

[a] Which is located inside sdkSampleProj\oxygen-sample-plugins\oxygen-sample-plugin-mathml\src\main\java\your\group\mathml\JEuclidRenderer.java
xml = "<!DOCTYPE math PUBLIC \"-//W3C//DTD MathML 2.0//EN\" \"http://www.w3.org/Math/DTD/mathml2/mathml2.dtd\">\n" + xml;
[c] mvn clean package -am -pl oxygen-sample-webapp -DskipTests

[1] https://www.oxygenxml.com/oxygen_sdk_maven.html
[2] mvn archetype:generate -DarchetypeGroupId=com.oxygenxml.samples -DarchetypeArtifactId=oxygen-sdk-samples-archetype -DarchetypeVersion=18.1.0.0 -DgroupId=myGroup -DartifactId=mySample -Dversion=1.0-SNAPSHOT -DarchetypeRepository=http://oxygenxml.com/maven/

Thanks for the help, now everything works.
The problem was in the rendering of formulas in the images.

Hello,

I wanted to let you know that Web Author version 19.0 is released and that the MathML plugin is now more tolerant with the namespace of the MathML namespace.

Cristian
