Linda, I wonder if this is a bug in the MARCslim2MADS.xslt? The error
message is
runtime error: file ./MARC21slim2MADS.xsl line 1404 element attribute
xsl:attribute: Cannot add attributes to an element if children have
been already added to the element.
I agree that it looks like the problem is when the xslt is
processing the 755 and trying to set the authority source.
I think the bug may be that when processing the 755 tag on line
1081, the genre template is called before the setAuthority
template. The Genre template adds child elements, then the
setAuthority tries to set attributes, which is where the error pops up.
If I swap lines 1084 and 1085 then the error goes away and both the
genre(155) and related genre(755) show up in the transformed xml.
I think the way to report this to the MADS project is via the MODS
listserv, as listed on http://www.loc.gov/standards/mads/
I don’t have enough experience with these technologies to be all
that confident that this is the issue though. I would be happy to
report this to the MODS listserv if it seems to make sense to
someone that is more familiar with mods/mads/xml/authorities.

155 field
Dear Josh,
Thank you for letting me know about the right XSL file!
After some more investigations I have come to a conclusion that it
is not actually a 155 field which causes the problem but a 755
field. If it has any value in second indicator, xsltproc fails to
process it. When the indicator does not have any value (or, to be
more precise, there is just a space), it is okay.
So far, it seems that we will have to get rid either of the values
of indicators in 755s, or of the following part of the XSL file:
<xsl:when
test="(700 <=
ancestor-or-self::marc:datafield/@tag and
ancestor-or-self::marc:datafield/@tag <= 755 ) and @ind2='7'">
<xsl:attribute name="authority">
<xsl:value-of select="marc:subfield[@code='2']"/>
</xsl:attribute>
</xsl:when>
Hopefully it will work for us and let us proceed in the upgrade :-)!
Linda

Hello Linda, I think the Authority ingest uses the
MARC21slim2MADS.xsl transform file to convert the authority data
into MADS format. Could you try manually processing your problem
authority record using the MADS file instead of the MODS and see
what you get.
The MADS xsl does look like it references tag 155.

Subject: [OPEN-ILS-GENERAL] Cannot save authority record with a 155
field
Hi,
back in August we started investigating why we couldn't proceed with
upgrade from 2.12.6 to 3.1.4 (for more details please see
http://libmail.georgialibraries.org/pipermail/open-ils-general/2018-August/015298.html).
After removing obviously invalid MARCXML records (which surprisingly
made their way to our 2.12 installation) we still have some records
which cannot be reingested (or saved).
Attached is a sample record americke_romany.xml which is one of
those troublesome ones. It is a genre/form term record with the main
heading in the field 155.
We have tried the SQL upgrade from 2.12.6 to 3.0.0 without authority
records reingest (the particular lines were commented out) and, once
we were at 3.1.4, used the web client to save this particular record
(without actually making any changes in it). However, it appeared
that it could not be saved:

xsl:attribute: Cannot add attributes to an element if children have

at line 31.
CONTEXT: PL/Perl function "oils_xslt_process"
---
Using this error message, we began to suspect a XSLT transformation
being the culprit. We have taken XSL files from Evergreen (those
from
http://git.evergreen-ils.org/?p=Evergreen.git;a=tree;f=Open-ILS/xsl;h=68fd13ffb2ad01ef9ceacf9f18695f25d284df05;hb=HEAD).
When they were used (xsltproc MARC21slim2MODS33.xsl
americke_romany.xml > output.xml), the contents of the 155 field
(which is a heading and therefore one of the most important parts of
the record) was never included in the output (please see the
attached output.xml file).
Then we used a web client again to change the 155 tag to the 100 tag
(and deleted another possible troublesome tag 755). After making
these changes, the record could be saved.
So the question is:
Where should we add the 155 field (probably in which of the XSLT
files) to make sure those records can be saved (or of course
reingested)?
Thank you in advance for any hints!
Linda
