I am trying to return a computed element with a computed attribute. I have Google'd and RTFM'd this.
Assume the element name and attribute name are in variables:
let $elname := "book"
let $attrname := "title"
I know I can create an element with:
element {$elname} {'content'}
and an attribute:
attribute {$attrname} {'value'}
But how do I create:
<book title="something"/>
I've tried every permutation I can imagine. Thanks very much.
Try:
element {$elname} {attribute {$attrname} {'something'}}
Here's an example of <book> also containing content:
element {$elname} {attribute {$attrname} {'something'},'foo'}
This would produce:
<book title="something">foo</book>
Figured this out:
return element {'joe'} { attribute {'x'} {'e'}, 'z' }

To select all elements that start with the class name foo. I can use:
[class^="foo"] { }
What can I use to select a custom element that starts with foo.
Example:
<foo-bar>Hola</foo-bar>
<foo-bazz>Hola</foo-bazz>
I want to have a single selector for both elements.
You can't. The [...] selectors only work on attributes, not element types themselves.
What you can do though, as I'm sure you're already aware, is chain them all into one selectors group, but this will mean that you'll need to know the exact element names:
foo-bar,
foo-bazz {
...
}
Failing that, you can always just give them all a shared class or data-* attribute:
<foo-bar class="foo"></foo-bar>
<foo-bazz class="foo"></foo-bazz>
.foo {
...
}
I have something like this
<a>
<b>
<c>1</c>
<d>2<e>3</e></d>
</b>
</a>
and I want to obtain a sequence like this
<a/>
<b/>
<c>1</c>
<d>2<e>3</e></d>
that is, when recursing, every time an element occurs which does not have a text node, I want to output the element as an empty element, whereas every time an element with a text node occurs, I want to output it as it is. Of course, the text nodes in the above input have to be space-normalized.
If I put it through a standard identity transform,
declare function local:copy($element as element()) as element() {
element {node-name($element)}
{$element/#*,
for $child in $element/*
return
if ($child/text())
then $child
else (element {node-name($child)}{$child/#*}, local:copy($child))
}
};
<b> gets reconstructed as a full element (containing <c> and <d>), but if I remove the element constructor, it does not get output at all.
I don't quite get the fourth line in your example output, I'm just guessing what you want is actually this:
<a/>
<b/>
<c>1</c>
<d>2</d>
<e>3</e>
You don't need any functions. Just list all elements, reconstruct one with same name and include it's text node children.
for $element in //*
return element { local-name($element) } { $element/text() }
This version is even shorter, but I think it requires XQuery 3.0, because earlier versions did not allow element constructors in step expressions:
//*/element { local-name(.) } { text() }
in css, to match multiple attributes you can use:
selector[attr1][attr2]{
code goes here
}
is there any way to have css match attributes using boolean logic? for example:
selector[attr1]OR[attr2]{
code goes here
}
would apply to any instance of that selector that has attr1, attr2, or both!
does this exist? If so, what is the syntax?
Use
selector[attr1], selector[attr2]{
code goes here
}
I have a question.
I have elements something like this:
<a> element with id = someGenerated Some:Same:0:name
<a> element with id = someGenerated Some:Same:0:surname
<a> element with id = someGenerated Some:Same:1:name
<a> element with id = someGenerated Some:Same:1:surname
I need CSS selector to get names. The problem is that I don't know how to get it.
I tried a[id*='Some:Same'] - it returned all <a> elements. After I can get elements which id ends with name. But I don't like this idea. I think that it can be done with some other selector.
Try this:
a[id*='Some:Same'][id$='name']
This will get you all a elements with id containing
Some:Same
and have the id ending in
name
<div id='element_123_wrapper_text'>My sample DIV</div>
The Operator ^ - Match elements that starts with given value
div[id^="element_123"] {
}
The Operator $ - Match elements that ends with given value
div[id$="wrapper_text"] {
}
The Operator * - Match elements that have an attribute containing a given value
div[id*="123_wrapper"] {
}
The only selector I see is a[id$="name"] (all links with id finishing by "name") but it's not as restrictive as it should.
Hay I have an element like this
<span class='a.b'>
Unfortunately this class name comes from an eCommerce application and cannot be changed.
Can I style a class name with a dot in it?
like
.a.b { }
.a\.b { }
However there could be browsers around that don't support this.
Coming very late to this party, but you can use attribute selectors.
In your case, to target the class='a.b' element, you could use:
[class~="a.b"] {...}
// or
span[class~="a.b"] {...}
Additionally, here is the full list of attribute selectors.
Attribute Present Selector
// Selects an element if the given attribute is present
// HTML
<a target="_blank">...</a>
// CSS
a[target] {...}
Attribute Equals Selector
// Selects an element if the given attribute value
// exactly matches the value stated
// HTML
...
// CSS
a[href="http://google.com/"] {...}
Attribute Contains Selector
// Selects an element if the given attribute value
// contains at least once instance of the value stated
// HTML
...
// CSS
a[href*="login"] {...}
Attribute Begins With Selector
// Selects an element if the given attribute value
// begins with the value stated
// HTML
...
// CSS
a[href^="https://"] {...}
Attribute Ends With Selector
// Selects an element if the given attribute value
// ends with the value stated
// HTML
...
// CSS
a[href$=".pdf"] {...}
Attribute Spaced Selector
// Selects an element if the given attribute value
// is whitespace-separated with one word being exactly as stated
// HTML
...
// CSS
a[rel~="tag"] {...}
Attribute Hyphenated Selector
// Selects an element if the given attribute value is
// hyphen-separated and begins with the word stated
// HTML
...
// CSS
a[lang|="en"] {...}

Perhaps you could scan the elements for these classes and add a class that you could style.
For instance, scan all elements with the “a.b” class and then add a new “style-ab” class or some such.
I haven’t posted any example code for this as people may want to use vanilla Javascript or jQuery and it’s a simple enough thing to do.
To clarify, my gaming framework does exactly as the OP described so translations could be applied to certain divs and spans. It’s not a nasty way to decide class names, it’s just useful for people creating markup when using a dictionary that has keys for phrases
Yes you can.
The meaning of CSS class name like '.a.b' is targeting elements that have CSS name with 'a' which also has class name 'b',that's to say you have both of these class in the same element. Just as div.cssname targeting div elements with cssname.
