Is catchfilebetweentags compatible with endfloat?

Question

I am using catchfilebetweentags to add figures to a document as described here. I get an error when additionally using the endfloat package. Here is an example:

Main file:

\documentclass[11pt]{article} 
\usepackage{catchfilebetweentags} 
\newcommand{\loadFigure}[1]{ % define command to load figures
    \ExecuteMetaData[figures_file]{#1} 
}
%\usepackage{endfloat} %un-comment to produce error
\begin{document}
Hello world\\   
\loadFigure{fig:figure1}
\end{document}

Secondary/figures file (figures_file.tex):

%<*fig:figure1>
\begin{figure}[htpb!]
    \caption{A figure}
\end{figure}
%</fig:figure1>

The error is produced by un-commenting \usepackage{endfloat}. Error message:

! Undefined control sequence.
\GenericError  ...                                
                                                    #4  \errhelp \@err@     ...
l.9 \loadFigure{fig:figure1}

I know this might seem like an odd thing to want to do, but I mostly want the figures at position in the text, but occasionally want them at the end (e.g. if en editor asks me to put them there).

Answer 1

The problem seems to be related to the issue explained here: a problem in endfloat with floats added via macro. I adapted a solution provided there by Axel-Sommerfeldt that works. The following should be added to the preamble when enabling endfloat:

\DeclareDelayedFloatFlavour{loadFigure}{figure}
\makeatletter
\newcommand\my@efloat@if@end[3]{#3#2}
\pretocmd\loadFigure{%
    \begingroup
    \let\efloat@if@end\my@efloat@if@end}{}{}
\makeatother

See explanation at the link above. That example loads the etoolbox package but I find this runs successfully without it. Note that this likely causes further conflicts; I already noticed one with floatrow.
