Well, it could, but you'd still have to provide the full XML as string, what might be wasteful. In my opinion, xml_parse_stream() would be nice to have, but on the other hand, that can easily be written in userland as well. ------------------------------------------------------------------------ [2020-05-27 15:08:01] php4fan at gmail dot com > The problem might be that XML_PARSE_HUGE is not set; Yep, found out that's the problem.

Yep, I worked around it by parsing in chunks. (why can't parse_xml() do it internally, by the way?) ------------------------------------------------------------------------ [2020-05-27 14:50:36] cmb@php.net The problem might be that XML_PARSE_HUGE is not set; unfortunately, it is currently not possible to pass that option via xml_parser_set_option() or otherwise. Anyway, it may be better to parse in chunks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
