Hello,

Using selector: .select("p:not([^])") as recommended, and probably working in that version, in https://stackoverflow.com/questions/32623325/getting-element-with-no-attributes-using-jsoup is giving this exception with the last version.

<html>
 <head></head>
 <body>
  <div id="intro">
   <h1 class="some class">
    <p id="some_id">Some text 1</p>
    <p name="some_name">Some text A</p>
    <p data>Some text B</p>
    <p>Some text 2</p></h1>
  </div>
 </body>
</html>

org.jsoup.nodes.Document docc = Jsoup.parse(html);
org.jsoup.select.Elements els = docc.select("p:not([^])");
for (org.jsoup.nodes.Element el:els){
System.out.println(el.text());
}

Exception in thread "main" org.jsoup.select.Selector$SelectorParseException: String must not be empty
at org.jsoup.select.QueryParser.parse(QueryParser.java:48)
at org.jsoup.select.QueryParser.not(QueryParser.java:433)
at org.jsoup.select.QueryParser.parsePseudoSelector(QueryParser.java:216)
at org.jsoup.select.QueryParser.consumeEvaluator(QueryParser.java:179)

at org.jsoup.select.Selector.select(Selector.java:98)
at org.jsoup.nodes.Element.select(Element.java:452)

Using xpath selector the result is ok but I think that performance is very bad:
.selectXpath("//p[not(@*)]")

It is possible to get the same result using css selector or jsoup selector?

Thanks in advance.

Interesting, the [^] was relying on the attribute name starting with selector and using an empty string.

Probably best to add an explicit [*] operator that looks for >0 attributes.

Hello,

Te result of:

org.jsoup.nodes.Document docc = Jsoup.parse(html);
org.jsoup.select.Elements els = docc.select("p:not([*])");
for (org.jsoup.nodes.Element el:els){
System.out.println(el.text());
}

is all 'p' elements:

Some text 1
Some text A
Some text B
Some text 2

Thanks in advance.

Yes, sorry, I mean to say it will be best if we add a new selector [*] to explicitly find elements with > 0 attributes. It's not supported currently.

OK, now [*] and [^] work. I added and documented [*] as it's functionally clearer, IMHO.

### [`v1.17.2`](https://github.com/jhy/jsoup/blob/HEAD/CHANGES.md#&#8203;1172-2023-Dec-29)

##### Improvements

-   **Attribute object accessors**: Added `Element.attribute(String)` and `Attributes.attribute(String)` to more simply
    obtain an `Attribute` object. [2069](jhy/jsoup#2069)
-   **Attribute source tracking**: If source tracking is on, and an Attribute's key is changed (
    via `Attribute.setKey(String)`), the source range is now still tracked
    in `Attribute.sourceRange()`. [2070](jhy/jsoup#2070)
-   **Wildcard attribute selector**: Added support for the `[*]` element with any attribute selector. And also restored
    support for selecting by an empty attribute name prefix (`[^]`). [2079](jhy/jsoup#2079)

##### Bug Fixes

-   **Mixed-cased source position**: When tracking the source position of attributes, if the source attribute name was
    mix-cased but the parser was lower-case normalizing attribute names, the source position for that attribute was not
    tracked correctly. [2067](jhy/jsoup#2067)
-   **Source position NPE**: When tracking the source position of a body fragment parse, a null pointer
    exception was thrown. [2068](jhy/jsoup#2068)
-   **Multi-point emoji entity**: A multi-point encoded emoji entity may be incorrectly decoded to the replacement
    character. [2074](jhy/jsoup#2074)
-   **Selector sub-expressions**: (Regression) in a selector like `parent [attr=va], other`, the `, OR` was binding
    to `[attr=va]` instead of `parent [attr=va]`, causing incorrect selections. The fix includes a EvaluatorDebug class
    that generates a sexpr to represent the query, allowing simpler and more thorough query parse
    tests. [2073](jhy/jsoup#2073)
-   **XML CData output**: When generating XML-syntax output from parsed HTML, script nodes containing (pseudo) CData
    sections would have an extraneous CData section added, causing script execution errors. Now, the data content is
    emitted in a HTML/XML/XHTML polyglot format, if the data is not already within a CData
    section. [2078](jhy/jsoup#2078)
-   **Thread safety**: The `:has` evaluator held a non-thread-safe Iterator, and so if an Evaluator object was
    shared across multiple concurrent threads, a NoSuchElement exception may be thrown, and the selected results may be
    incorrect. Now, the iterator object is a thread-local. [2088](jhy/jsoup#2088)
