parsing

问题 Consider a html like below, <div id="test"> {{ sometext }} </div> <span class="testing"> {{ asdknfsdf }} </span> I want to get all the elements whose inner text matches {{ <sometext> }} in jquery. I tried the below code, but I could not get the elements properly. What am I missing here? var elements = []; $('*:contains("{{ .* }}")').each(function(){ elements.push(this); }); 回答1: Several things: 1) "Could not get the elements properly" isn't terribly descriptive. Are you getting no results?

问题 I'm using Django and Python 3.7. I want to have more efficient parsing so I was reading about SoupStrainer objects. I created a custom one to help me parse only the elements I need ... def my_custom_strainer(self, elem, attrs): for attr in attrs: print("attr:" + attr + "=" + attrs[attr]) if elem == 'div' and 'class' in attr and attrs['class'] == "score": return True elif elem == "span" and elem.text == re.compile("my text"): return True article_stat_page_strainer = SoupStrainer(self.my_custom

问题 The boost::spirit::x3 error handling utilities allow for the user to choose what is shown to the user when an expectation failure occurs. This, however, does not seem to be the case for the line number portion of the message, which is exactly what I'd like to modify. So instead of it printing out In line 1: etc. I would like to print some other message in it's place with the same line number info. Anyone know how I could do that, or if it is even modifiable in the first place? EDIT: Here's

问题 I have a specified JSON document, like this: { "user":"human1", "subsystems":[1,2,3], "query":{"AND":[ {"eq":["key1","val1"]}, {"eq":["key2","val2"]}, {"OR":[ {"eq":["subkey1","subval1"]}, {"eq":["subkey2","subval2"]}]} ] } } Expected transformation of the query field: (key1 eq val1 and key2 eq val2 and (subkey1 eq subval1 OR subkey2 eq subval2)) I am using Newtonsoft.Json ( JsonConvert.DeserializeObject ), and I don't understand how to transform this field. 回答1: Well, like most things, there

问题 Recently I started working with sockets. I realized that when reading from a network stream, you can not know how much data is coming in. So either you know in advance how many bytes have to be recieved or you know which bytes . Since I am currently trying to implement a C# WebSocket server I need to process HTTP requests. A HTTP request can have arbitrary length, so knowing in advance how many bytes is out of the question. But a HTTP request always has a certain format. It starts with the
