问题 I need to parse a file .xsd in Python as i would parse an XML. I am using libxml2. I have to parse an xsd that look as follow: <xs:complexType name="ClassType"> <xs:sequence> <xs:element name="IeplcHeader"> <xs:complexType> <xs:sequence> <xs:element name="device-number" type="xs:integer" fixed="1"/> </xs:sequence> <xs:attribute name="version" type="xs:integer" use="required" fixed="0"/> </xs:complexType> </xs:element> when i access with doc.xpathEval('//xs:complexType/xs:sequence/xs:element[

问题 I have a binary file made from C structs that I want to parse in Python. I know the exact format and layout of the binary but I am confused on how to use Python Struct unpacking to read this data. Would I have to traverse the whole binary unpacking a certain number of bytes at a time based on what the members of the struct are? C File Format: typedef struct { int data1; int data2; int data4; } datanums; typedef struct { datanums numbers; char *name; } personal_data; Lets say the binary file

问题 Until now, I've always used relational databases (and was quite happy indeed!). However, recently, I discovered Parse and found it quite nice so decided to give it a try. However, it comes with a NoSQL database. I am still trying to get my head around it. So my question is, how would you recommend achieving localisation? I could think of the following approaches, what do you think? Approach A: Have a single 'strings' field on the document and store all language specific data in that field.

问题 We need to parse Received: email headers according to RFC 5321. We need to extract domain\IPs through which the mail has traversed.Also, we need to figure if an IP is an internal IP. Is there already a library which can help out , especially in C\C++. For example, Received: from server.mymailhost.com (mail.mymailhost.com [126.43.75.123]) by pilot01.cl.msu.edu (8.10.2/8.10.2) with ESMTP id NAA23597; Fri, 12 Jul 2002 16:11:20 -0400 (EDT) We need to extract the "by" server. thanks 回答1: The

问题 Given the email address: "Jim" <jim@example.com> If I try to pass this to MailAddress I get the exception: The specified string is not in the form required for an e-mail address. How do I parse this address into a display name (Jim) and email address (jim@example.com) in C#? EDIT: I'm looking for C# code to parse it. EDIT2: I found that the exception was being thrown by MailAddress because I had a space at the start of the email address string. 回答1: If you are looking to parse the email

问题 I need to strip out all non standard text characers from a string. I need remove all non ascii and control characters (except line feeds/carriage returns). 回答1: Something like this should do: // For those who need a disclaimer: // This code is meant as a sample to show you how the basic check for non-ASCII characters goes // It will give low performance with long strings that are called often. // Use a TStringBuilder, or SetLength & Integer loop index to optimize. // If you need really
