copied!<p>unwind's suggestion of using the ast module in 2.6 is a good one. (There's also the undocumented _ast module in 2.5.) Here's example code for that</p> <pre><code>code = """a = 'blah' b = '''multi line string''' c = u"spam" """ import ast root = ast.parse(code) class ShowStrings(ast.NodeVisitor): def visit_Str(self, node): print "string at", node.lineno, node.col_offset, repr(node.s) show_strings = ShowStrings() show_strings.visit(root) </code></pre> <p>The problem is multiline strings. If you run the above you'll get.</p> <pre><code>string at 1 4 'blah' string at 4 -1 'multi\nline\nstring' string at 5 4 u'spam' </code></pre> <p>You see that it doesn't report the start of the multiline string, only the end. There's no good solution for that using the builtin Python tools.</p> <p>Another option is that you can use my '<a href="http://dalkescientific.com/Python/python4ply.html" rel="nofollow noreferrer">python4ply</a>' module. This is a grammar definition for Python for <a href="http://www.dabeaz.com/ply/" rel="nofollow noreferrer">PLY</a>, which is a parser generator. Here's how you might use it:</p> <pre><code>import compiler import compiler.visitor # from python4ply; requires the ply parser generator import python_yacc code = """a = 'blah' b = '''multi line string''' c = u"spam" d = 1 """ tree = python_yacc.parse(code, "<string>") #print tree class ShowStrings(compiler.visitor.ASTVisitor): def visitConst(self, node): if isinstance(node.value, basestring): print "string at", node.lineno, repr(node.value) visitor = ShowStrings() compiler.walk(tree, visitor) </code></pre> <p>The output from this is</p> <pre><code>string at 1 'blah' string at 2 'multi\nline\nstring' string at 5 u'spam' </code></pre> <p>There's no support for column information. (There is some mostly complete commented out code to support that, but it's not fully tested.) Then again, I see you don't need it. It also means working with Python's 'compiler' module, which is clumsier than the AST module.</p> <p>Still, with a 30-40 lines of code you should have exactly what you want.</p>
