findall

I need to find all matches in a string for a given regex. I've been using findall() to do that until I came across a case where it wasn't doing what I expected. For example: regex = re.compile('(\d+,?)+') s = 'There are 9,000,000 bicycles in Beijing.' print re.search(regex, s).group(0) > 9,000,000 print re.findall(regex, s) > ['000'] In this case search() returns what I need (the longest match) but findall() behaves differently, although the docs imply it should be the same: findall() matches all occurrences of a pattern, not just the first one as search() does. Why is the behaviour different?

re.findall("(100|[0-9][0-9]|[0-9])%", "89%") This returns only result [89] and I need to return the whole 89%. Any ideas how to do it please? The trivial solution: >>> re.findall("(100%|[0-9][0-9]%|[0-9]%)","89%") ['89%'] More beautiful solution: >>> re.findall("(100%|[0-9]{1,2}%)","89%") ['89%'] The prettiest solution: >>> re.findall("(?:100|[0-9]{1,2})%","89%") ['89%'] >>> re.findall("(?:100|[0-9][0-9]|[0-9])%", "89%") ['89%'] When there are capture groups findall returns only the captured parts. Use ?: to prevent the parentheses from being a capture group. Use an outer group, with the inner

I'm looking to scan a group of .cs files to see which ones call the Value property of a Nullable<T> (finding all references). For example, this would match: class Program { static void Main() { int? nullable = 123; int value = nullable.Value; } } I found out about Roslyn and looked at some of the samples, but many of them are outdated and the API is huge. How would I go about doing this? I'm stuck after parsing the syntax tree. This is what I have so far: public static void Analyze(string sourceCode) { var tree = CSharpSyntaxTree.ParseText(sourceCode); tree./* ??? What goes here? */ } You're

I'm trying to parse a website and get some info with BeautifulSoup.findAll but it doesn't find them all.. I'm using python3 the code is this #!/usr/bin/python3 from bs4 import BeautifulSoup from urllib.request import urlopen page = urlopen ("http://mangafox.me/directory/") # print (page.read ()) soup = BeautifulSoup (page.read ()) manga_img = soup.findAll ('a', {'class' : 'manga_img'}, limit=None) for manga in manga_img: print (manga['href']) it only prints the half of them... Different HTML parsers deal differently with broken HTML. That page serves broken HTML, and the lxml parser is not

I want to use the method of "findall" to locate some elements of the source xml file in the ElementTree module. However, the source xml file (test.xml) has namespace. I truncate part of xml file as sample: <?xml version="1.0" encoding="iso-8859-1"?> <XML_HEADER xmlns="http://www.test.com"> <TYPE>Updates</TYPE> <DATE>9/26/2012 10:30:34 AM</DATE> <COPYRIGHT_NOTICE>All Rights Reserved.</COPYRIGHT_NOTICE> <LICENSE>newlicense.htm</LICENSE> <DEAL_LEVEL> <PAID_OFF>N</PAID_OFF> </DEAL_LEVEL> </XML_HEADER> The sample python code is below: from xml.etree import ElementTree as ET tree = ET.parse(r"test
