# 需要导入模块: from lxml import etree [as 别名]
# 或者: from lxml.etree import XPath [as 别名]
def _details_prepare_merge(details):
# We may mutate the details later, so copy now to prevent
# affecting the caller's data.

# Prepare an nsmap in an OrderedDict. This ensures that lxml
# serializes namespace declarations in a stable order.
nsmap = OrderedDict((ns, ns) for ns in sorted(details))
# Root everything in a namespace-less element. Setting the nsmap
# here ensures that prefixes are preserved when dumping later.
# This element will be replaced by the root of the lshw detail.
# However, if there is no lshw detail, this root element shares
# its tag with the tag of an lshw XML tree, so that XPath
# expressions written with the lshw tree in mind will still work
# without it, e.g. "/list//{lldp}something".
root = etree.Element("list", nsmap=nsmap)
# We have copied details, and root is new.
