A have a string like '<node attr="some_value">'. How to remove attr="some_value" from this string? I know only attr attribute name and don't know "some_value" value.
P.S. I'm using JavaScript but solution for any language will be great. Thanks in advance.

Try this: Needs jquery.
var xml = '<node attr="some_value">';
var newXml = $(xml).removeAttr('attr');

Using Regexs to play with XML is begging for disaster down the line. I'd use built in Xml functionality to do this.
From w3schools.com
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('book');
document.write(x[0].getAttribute('category')); document.write("<br />");
x[0].removeAttribute('category');
document.write(x[0].getAttribute('category'));
Where the XML is
<bookstore>
<book category="cooking">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year>2005</year>
<price>30.00</price>
</book>
<book category="children">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>

classic solution : use String functions, for exemple :
str = str.substring(0,str.indexOf("attr")-1) + ">"
