Question

我想创建一个XPath查询，该查询返回其“作业”为“Actor”并且其“order”在以下XML中的“0”和“4”之间的演员。我发现很难创建一个同时执行这两个操作的查询。

<cast>
    <person name="David Silverman" character="" job="Director" order="0"/>
    <person name="James L. Brooks" character="" job="Author" order="0"/>
    <person name="Dan Castellaneta" character="Homer J. Simpson" job="Actor" order="0"/>
    <person name="Julie Kavner" character="Marge Simpson" job="Actor" order="1"/>
    <person name="Nancy Cartwright" character="Bart Simpson" job="Actor" order="2"/>
    <person name="Yeardley Smith" character="Lisa Simpson" job="Actor" order="3"/>
    <person name="Dan Castellaneta" character="Krusty the Clown" job="Actor" order="4"/>
    <person name="Hank Azaria" character="Moe Szyslak" job="Actor" order="5"/>
    <person name="Dan Castellaneta" character="Apu Nahasapeemapetilon" job="Actor" order="6"/>
</cast>
