Suppose I have XML like this:
<graph label="Test" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:cy="http://www.cytoscape.org" xmlns="http://www.cs.rpi.edu/XGMML" directed="1">
<foo>...</foo>
</graph>
The first element name with all its attributes all appear on one line.
I have seen how to pretty print the element tree, using lxml, with code like this:
from lxml import etree
...
def prettyPrintXml(filePath):
assert filePath is not None
parser = etree.XMLParser(resolve_entities=False, remove_blank_text=True,
strip_cdata=False)
document = etree.parse(filePath, parser)
print(etree.tostring(document, pretty_print=True, encoding='utf-8'))
... but using that, every element appears on one line.
Is there a magic incantation to tell the pretty printer to insert newlines between the element attributes so that, for example, the line length does not exceed 80 characaters?
I would like the result to look something like this:
<graph label="Test"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:cy="http://www.cytoscape.org"
xmlns="http://www.cs.rpi.edu/XGMML" directed="1">
<foo>...</foo>
</graph>
ps: I don't want to resort to subprocess and xmllint
