Subject: facturized DOM XML indexing code out into function
X-Git-Tag: ZEBRA.2.0.12~57
X-Git-Url: http://sru.miketaylor.org.uk/cgi-bin?a=commitdiff_plain;h=eec24169543303f147c70a5cf15f4c52169f5e2e;p=idzebra-moved-to-github.git

facturized DOM XML indexing code out into function
static void extract_doc_alvis(struct filter_info *tinfo,
                              struct recExtractCtrl *recctr,
                              xmlDocPtr doc)
This is the function to be re-written using both PI and <z:index> instructions,
and also fixing the bug of index type 'p' and '0' chop-over of merged content.
