xtpipes with \AtBeginDocument{\maketitle} in classfile

[hcf-n]

I have a classfile that causes errors when running make4ht. The line in the classfile causing the error is \AtBeginDocument{\maketitle}

The error is: xtpipes error 37 --- At <xslt name="." xml="." xsl="text-p" > : javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: The prefix "text" for element "text:p" is not bound.; The prefix "text" for element "text:p" is not bound.

MWE-class file:

\ProvidesClass{mwe}
\LoadClass[12pt, a4paper]{article}
\RequirePackage[norsk]{babel}
\RequirePackage{fontspec}
% Problematic line
\AtBeginDocument{\maketitle}

MWE:

\documentclass{mwe}
\title{Title}                                                                                                                                                                                                                                                                                                                                                 
\begin{document}
Hello World!
\end{document}

The problem is that when you add code using \AtBeginDocument like this, it is executed before all other tags, which results in error. You can use something like this instead:

\ProvidesClass{mwe}
\LoadClass[12pt, a4paper]{article}
\RequirePackage[norsk]{babel}
\RequirePackage{fontspec}
% Problematic line
% \AtBeginDocument{\maketitle}
\ifdefined\HCode
\AtBeginDocument{\Configure{@BODY}{\maketitle}}
\else
\AtBeginDocument{\maketitle}
\fi

The \AtBeginDocument{\Configure{@BODY}{\maketitle}} line ensures that the \maketitle is inserted at a correct place.

Thanks! That works.

That's good to hear. So I hope I can close this.
