[Question] How to check Zipped file format on LibreOffice

[DaeHyun Sung]

Hello, I'm DaeHyun Sung, from South Korea.

I found the Bugzilla report "tdf#144747 FILEOPEN When opening any Hancom
Word hwp document garbage is displayed"
https://bugs.documentfoundation.org/show_bug.cgi?id=144747
(Thanks Ming Hua to inform me. )

So, I read hwpfilter module on LibreOffice.
LibreOffice only supported hwp v3.0(HWP97 version) file format.
 However, In Korea, Broadly used to hwp v5.0 file format.
It is zipped Compound File Binary Format. So, I added read & check zipped
format

I submitted my works on gerrit (WIP)
https://gerrit.libreoffice.org/c/core/+/125782

Though, I added a check zip file format code.
But, It doesn't check and error.
Below is added  my code
===
 uno::Reference<uno::XComponentContext> xContext =
comphelper::getProcessComponentContext();
    SAL_WARN("HwpImportFilter::detect", "xContext");
    uno::Reference<packages::zip::XZipFileAccess2>  xZip(
        packages::zip::ZipFileAccess::createWithURL(xContext, sURL));

    if (xZip.is())
    {
        SAL_WARN("HwpImportFilter::detect", "That maybe HWP v5.0 format");
        uno::Reference<io::XInputStream> const
isHwpV5FileHeaderStream(xZip->getByName("FileHeader"),
                                                            uno::UNO_QUERY);
    }

===

In my opinion, I found the reading zip module follows LibreOffice core
source codes. But It doesn't works.
So, I have a question.

How to check Zipped file(It contained Compound File Binary Format) on
LibreOffice?

Check it please!
