Re: How to get the filename of files in an archive correctly?

Hello,

while using the XML output works very well I am getting validation errors.
I am validating against dar-catalog.dtd in catalog format version 1.2
(which I found here:
https://fossies.org/linux/privat/dar-2.7.0.tar.gz/dar-2.7.0/doc/dar-catalog.dtd?m=t)
. The parser complains about missing required attributes.
For example I have the following dar list output (of a differential archive):
<Catalog format="1.2">
</File>
<File name="&quot;
">
<Attributes data="deleted" metadata="absent" user="" group=""
permissions="" atime="" mtime="1620218204" ctime="" />
</File>
</Catalog>

and in the DTD:
[...]
<!ELEMENT File (Attributes)>
<!ATTLIST File name CDATA #REQUIRED>             <!-- string, entry
name             -->
<!ATTLIST File size CDATA #REQUIRED>             <!-- decimal, file
size in bytes    -->
<!ATTLIST File stored CDATA "" >                 <!-- decimal, stored
size in bytes  -->
<!ATTLIST File crc CDATA "" >                    <!-- hexadecimal, crc
sum of file   -->
<!ATTLIST File dirty CDATA #REQUIRED>            <!-- string, whether
file changed during backup -->
<!ATTLIST File sparse CDATA #REQUIRED>          <!-- string, whether
file is sparse -->
<!ATTLIST File delta_sig CDATA #REQUIRED>        <!-- string, whether
delta signature is present -->
<!ATTLIST File patch_base_crc CDATA "">          <!-- hexadecimal, crc
sum of the delta patch when present -->
<!ATTLIST File patch_result_crc CDATA "">        <!-- hexadecimal, crc
sum of the delta patch resulting file when present -->
[...]

Given these parameters the parser consequently complains about missing
attributes "size", "dirty", "sparse" and "delta_sig".

The easiest way for me to fix that as a workaround is to remove the
#required annotation in the DTD.

Best regards,
Stefan
