How to Perform Element Name Wildcard Matching in JavaScript Without Attribute Queries?

Wildcard Element Name Matching in JavaScript: QuerySelector and QuerySelectorAll

Finding elements with specific strings in their names is a common task when parsing XML documents. However, JavaScript's querySelector and querySelectorAll methods only support attribute queries with wildcards.

Alternative to XPath

Using XPath for wildcard element name matching is no longer recommended due to its deprecation in Internet Explorer 9. Therefore, alternative solutions are preferred.

Attribute Query Wildcards

Although element name wildcards aren't supported directly, attribute queries do provide wildcard matching capabilities:

• [id^='someId'] matches all elements with an id starting with "someId".
• [id$='someId'] matches all elements with an id ending with "someId".
• [id*='someId'] matches all elements with an id containing "someId".

To match the name attribute, simply substitute "id" with "name".

Element Tag Name Matching

Unfortunately, there is currently no direct way to perform wildcard matching on the element tag name using querySelector or querySelectorAll.
