lxml

问题 I have two XML files that I'm trying to merge. I looked at other previous questions, but I don't feel like I can solve my problem from reading those. What I think makes my situation unique is that I have to find elements by attribute value and then merge to the opposite file. I have two files. One is an English translation catalog and the second is a Japanese translation catalog. Pleas see below. In the code below you'll see the XML has three elements which I will be merging children on -

问题 Python 2.7 using lxml I have some annoyingly formed html that looks like this: <td> <b>"John" </b> <br> "123 Main st. " <br> "New York " <b> "Sally" </b> <br> "101 California St. " <br> "San Francisco " </td> So basically it's a single td with a ton of stuff in it. I'm trying to compile a list or dict of the names and their addresses. So far what I've done is gotten a list of nodes with names using tree.xpath('//td/b') . So let's assume I'm currently on the b node for John. I'm trying to get

问题 I am working to move nexted xml data into a hierarchical data frame. I was able to get all of the data out of the xml thanks to help on SO. However, now, I am working to clean up the data that I extract and shape it before output because I will be doing this thousands of times. UPDATED: THIS IS WHAT I EVENTUALLY WANT OUT. I cannot seem to fetch just the Time and value for channel dynamically. The channel names will change for each file. When channel = txt1[0] (for this file, txt1[0]="blah" )

问题 I have a problem with the find function in lXML. But i think this is more a generic question how to tell that i want to check against the value, not the object reference. So here is the code that works: step = xml_obj.find('.//step/name[text()="Design"]').getparent() If i try to replace the string with an object, the result is always None. stepn = 'Design' step = xml_obj.find('.//step/name[text()=stepn]').getparent() 'NoneType' object has no attribute 'getparent' 回答1: stepn = 'Design' step =

问题 Using Python 2.7 and lxml , how do I modify XML elements with multiple values? E.g. <Title> <Playcount>1</Playcount> <Genre>Adventure</Genre> <Genre>Comedy</Genre> <Genre>Action</Genre> </Title> It is straight forward to modify Playcount , as it has a single value.
