I know that I can preserve CDATA sections during XML parsing, using the following:
from lxml import etree
parser = etree.XMLParser(strip_cdata=False)
root = etree.XML('<root><![CDATA[test]]></root>', parser)
See APIs specific to lxml.etree
But, is there a simple way to "restore" CDATA section during serialization? For example, by specifying a list of tag names…
For instance, I want to turn:
<CONFIG>
<BODY>This is a <message>.</BODY>
</CONFIG>
to:
<CONFIG>
<BODY><![CDATA[This is a <message>.]]></BODY>
</CONFIG>
Just by telling that BODY
should contains CDATA…
Something like this?
from lxml import etree
parser = etree.XMLParser(strip_cdata=True)
root = etree.XML('<root><x><![CDATA[<test>]]></x></root>', parser)
print etree.tostring(root)
for elem in root.findall('x'):
elem.text = etree.CDATA(elem.text)
print etree.tostring(root)
Produces:
<root><x><test></x></root>
<root><x><![CDATA[<test>]]></x></root>
