Hi,
I’m currently trying out some text editors for MathML in DTBook
documents. I’ve installed XMLmind XML Editor 7.2.0 and I noticed that
the whitespace within MathML elements is automatically stripped. For
example:
<m:math xmlns:dtbook="http://www.daisy.org/z3986/2005/dtbook/";
display="inline">
<m:mn>6</m:mn>
<m:mrow>
<m:mtext> km</m:mtext>
</m:mrow>
<m:mo>/</m:mo>
<m:mrow>
<m:mtext>h</m:mtext></m:mrow></m:math>
When opened in XMLmind becomes:
<m:math xmlns:dtbook="http://www.daisy.org/z3986/2005/dtbook/";
display="inline">
<m:mn>6</m:mn>
<m:mrow>
<m:mtext>km</m:mtext>
</m:mrow>
<m:mo>/</m:mo>
<m:mrow>
<m:mtext>h</m:mtext></m:mrow></m:math>
Is there any possibility to avoid this?
No, there is no way to avoid this other than "fixing" the schema of
MathML. I mean, <m:mtext> has no xml:space="preserve" as a default
attribute.
It seems that the MathML schema (which comes from the W3C; not from
XMLmind) is incorrect in that respect because the spec says:
---
An mtext element can be used to contain "renderable whitespace"
---
https://www.w3.org/TR/MathML2/chapter3.html#presm.mtext
We'll carefully re-read the spec in order to try to fix the problem in
the next release of XXE.
