问题 I know variants of this question have been asked a number of times but I've not been able to crack it and get what I want. I have a website which has a few tables in it. The table of interest contains a column where each row contains the word Text hyperlinked to a different page. Here is a specific example from the first row on the above linked page: <a href="_alexandria_RIC_VI_099b_K-AP.txt">Text</a> This is the general pattern: <a href="_something_something-blah-blah.txt">Text</a> Right now

问题 I'm trying to iterate through an XML file (UTF-8 encoded, starts with ) with lxml, but get the following error on the character 丂 : UnicodeEncodeError: 'cp932' codec can't encode character u'\u4e02' in position 0: illegal multibyte sequence Other characters before this are printed out correctly.

问题 Here is a small section of an xml file. I would like to create a database from this with each tag unique columns names and non-duplicated data. Tried using lxml and the best I have been able to do so far is to create a dataframe that results in something like this: " SRCSGT DATE 11112017 AGENCY Department of Veterans Affairs OFFICE Canandaigua VAMC LOCATION Department of Veterans Affairs Medical Center ZIP 14424 etc, etc, " The xml <?xml version="1.0" encoding="UTF-8"?> <NOTICES> <SRCSGT>

问题 I had issues in getting the text value of and nodes using lxml where the XML text has namespaces in it. I was using findall('Status') but the result was always coming to null. I arrived at the following working code in the end....Is this the correct way of using lxml for fetching node values?

Code: doc = etree.XML("""<root><a>1</a><b><c></c></b><d></d></root>""") def remove_empty_elements(doc): for element in doc.xpath('//*[not(node())]'): element.getparent().remove(element) I also need to do it with lxml and not BeautifulSoup. 回答1: This XPath, //*[not(*)][not(normalize-space())] will select all leaf elements with only whitespace content. For

问题 I am currently serializing some largish XML files in Python with lxml. I want to use the incremental writer for that. My XML format heavily relies on namespaces and attributes. When I run the following code from io import BytesIO from lxml import etree sink = BytesIO() nsmap = { 'test': 'http://test.org', 'foo': 'http://foo.org', 'bar': 'http://bar.org', } with etree.xmlfile(sink) as xf: with xf.element("test:testElement", nsmap=nsmap): name = etree.QName(nsmap["foo"], "fooElement") elem =
