Not support Square root

[hoangvubrvt]

Hi, I'm building a tool to convert MathType in docx file to Latex. I'm using this lib to convert MathType to MathML and then MathML to Latex. And then I figured out that this lib is not support to convert Square Root, I think it is the basic in Math now, do you have any idea to do this or any plan to support?

Thanks for you awesome work!

Have you fixed the above error I am having the same error

I found the root cause of this issue.

The original MathType → MathML XSLT set does NOT include the template
for handling square roots (tmROOT). Because of that, any expression
containing √ or an nth-root will not be converted correctly.

To fix it, I added the missing root.xsl (copied from the official
transpect/mathtype-extension implementation). After adding this file
and including it in transform.xsl, the square root is converted
correctly.

Here is the exact XSLT template I added:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.w3.org/1998/Math/MathML"
exclude-result-prefixes="xs"
version="1.0">

<xsl:template match="tmpl[selector = 'tmROOT'][variation = 'tvROOT_SQ']">

<xsl:apply-templates select="slot[1] | pile[1]"/>

</xsl:template>

<xsl:template match="tmpl[selector = 'tmROOT'][variation = 'tvROOT_NTH']">

<xsl:apply-templates select="slot[1] | pile[1]"/>
<xsl:apply-templates select="slot[2] | pile[2]"/>

</xsl:template>
</xsl:stylesheet>

After adding this file, all square roots render correctly in MathML.
I can confirm the issue is fully resolved now.
