Question

I want to get all xml elements (xml descendents) which have some attributes like:

<books>
    <book concept="rr" author="xx"/>
    <book concept="tt" />
    <book concept="yy" />
    <book concept="uu" author="xx"/>
</books>

I need to perform a xml descendent search for xml nodes with author attribute containing
results should be:

<book concept="rr" author="xx"/>
<book concept="uu" author="xx"/>

Answer 1

Or with XML selectors:

var booksXML: XML = <books>
    <book concept="rr" author="xx"/>
    <book concept="tt" />
    <book concept="yy" />
    <book concept="uu" author="xx"/>
</books>

var haveAuthor:XMLList = booksXML.book.(attribute("author").length() > 0);
//booksXML.book.(@author) won't work
