Is XML case-sensitive?

阅读更多关于 Is XML case-sensitive?

Short question Is XML case-sensitive? Longer question For example: <Shirt color="Red"/> The attribute color is of type string that may contain a set of valid colors ( Red , Blue and Green ). To validate the XML, I used the following XSD: <xs:simpleType name="ColorType"> <xs:restriction base="xs:string"> <xs:enumeration value="Red"/> <xs:enumeration value="Blue"/> <xs:enumeration value="Green"/> </xs:restriction> </xs:simpleType> Am I expected to accept different case variations of Red, Blue and Green? Or XML is widely accepted as case-sensitive? Jon Egerton Short Answer: Yes - XML is case

Reason why oracle is case sensitive?

阅读更多关于 Reason why oracle is case sensitive?

Is there a reason why Oracle is case sensitive and others like SQL Server, and MySQL are not by default? I know that there are ways to enable/disable case sensitivity, but it just seems weird that oracle differs from other databases. I'm also trying to understand reasons for case sensitivity. I can see where "Table" and "TaBlE" can be considered equivalent and not equivalent, but is there an example where case sensitivity would actually make a difference? I'm somewhat new to databases and am currently taking a class. By default, Oracle identifiers (table names, column names, etc.) are case-

Here is an example from the Immediate window to show how StrComp() works. See

Is it possible for lxml to work in a case-insensitive manner?

阅读更多关于 Is it possible for lxml to work in a case-insensitive manner?

问题 I'm trying to scrape META keywords and description tags from arbitrary websites. I obviusly have no control over said website, so have to take what I'm given. They have a variety of casings for the tag and attributes, which means I need to work case-insensitively. I can't believe that the lxml authors are as stubborn as to insist on full forced standards-compliance when it excludes much of the use of their library. I'd like to be able to say doc.cssselect('meta[name=description]') (or some

On which operating systems or browsers are CSS font-family names case-sensitive

阅读更多关于 On which operating systems or browsers are CSS font-family names case-sensitive

问题 According to sitepoint ( a source I typically highly trust ) when specifying font-family names some Operating Systems/Browsers may be case-sensitive . I've typically always used mixed-case values but I'm wondering if lower-case values will work just the same? I don't have an overwhelming preference either way - but I'd hate for a page to render differently because I typed a lower-case "v" vs. "V" somewhere in a CSS file. e.g. are there any known cases where 2 divs with the foo and bar classes

Why is Common Lisp case insensitive?

阅读更多关于 Why is Common Lisp case insensitive?

问题 Is there an advantage to defining a function like (defun hi () "Hi!") and be able to call it by using (hi) or (HI) or (Hi) , or to (setf a-number 5) and be able to access that number using a-number , A-NUMBER , or A-Number ? If there is such an advantage, then why are most other languages case-sensitive? 回答1: Using case sensitive names in code within an interactive session is just more error-prone. Common Lisp is case sensitive. It is just that the Common Lisp reader functionality by default

MYSQL case sensitive search for utf8_bin field

阅读更多关于 MYSQL case sensitive search for utf8_bin field

问题 I created a table and set the collation to utf8 in order to be able to add a unique index to a field. Now I need to do case insensitive searches, but when I performed some queries with the collate keyword and I got: mysql> select * from page where pageTitle="Something" Collate utf8_general_ci; ERROR 1253 (42000): COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'latin1' mysql> select * from page where pageTitle="Something" Collate latin1_general_ci; ERROR 1267 (HY000): Illegal mix

OData query $filter conditions and case-sensitivity

阅读更多关于 OData query $filter conditions and case-sensitivity

问题 Does OData specify whether filter conditions on string fields are to be evaluated case-sensitively or case-insensitively? Example: (from the docs) /Suppliers?$filter=Address/City eq 'Redmond' Is this expected to be case-sensitive or not? If I want to offer both options, how can this be expressed? There is a tolower() function that can be used like: /Suppliers?$filter=tolower(Address/City) eq 'redmond' or /Suppliers?$filter=tolower(Address/City) eq tolower('Redmond') Isn't there a more concise

Are column and table name case sensitive in MySQL?

阅读更多关于 Are column and table name case sensitive in MySQL?

If I have a column names called category_id and Category_Id , are they different? And if I have table called category and Category , are they different? On Unix, table names are case sensitive. On Windows, they are not. Fun, isn't it? Kinda like their respective file systems. Do you think it's a coincidence? In other words, if you are planning on deploying on a Linux machine, better test your SQL against a Linux-based MySQL too, or be prepared for mysterious "table not found" errors at prod time. VMs are cheap these days. Field names are case-insensitive regardless. EDIT: we're talking about

Is VB really case insensitive?

阅读更多关于 Is VB really case insensitive?

I'm not trying to start an argument here, but for whatever reason, it's typically stated that Visual Basic is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is Visual Basic case insensitive? When I type... Dim ss As String Dim SS As String ...into the Visual Studio 2008 or Visual Studio 2010 IDE, the second one has a warning of " Local variable SS is already declared in the current block ". In the VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this
