java - In what context are angle brackets escaped with backslashes? -


A bit of abnormal question - angle brackets in angle context are escaped from backslashes?

I am sending a XML document (string XSD type) through the web service, which saves it in the database, but I see that all the XML Angle brackets escaped backslash So, I'm thinking that in fact (Java XML) document builder and transformer, using the web

example:

desired XML: 

 < Code> & lt ;? XML version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Ultimate & gt; & Lt; Ultimate name = "qqq" & gt; 1 & lt; / Param & gt; & Lt; / Ultimate & gt;

Actual results: 

  \ & lt ;? Xml version center code = "1.0" encoding = "UTF-8"? \ & Gt; \ & Lt; Ultimate & gt; \ & Lt; Param name = "qqq" \ gt; 1 \ & lt; / Param \ & gt; \ & Lt; / Absolute \ & gt;

Left angle bracket characters are not saved in valid HTML or XML like this In the formats '& lt;' characters in "& amp; lt;" In particular, I do not expect XML Builder / Serializer or a webservices stack to do this in accordance with standard standards.

They are not escaping in that way if you were crazy enough to embed XML in a URL, then you would use the "% xx" encoding.

I do not know why a DBMS needs a character to do this

The only normal situation I can think of is that you do not have to type it on '\' Where to use a to avoid in some Wiki markup languages

IMO, most likely it is some application-specific concern with the web service you are using.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
