如何在python中生成多个不在一起的矩形？

用xpath找到file这个节点，然后寻找其子节点比较filename的名字是否相等，如果相等的话直接返回其父节点，然后用root删除掉该节点，代码如下 node2=root.xpath("/root/file") for i in range(len(node2)): ... for c in node2[i]: ... if c.text=='as': ... print i ... root.remove(node2[i]) Traceback (most recent call last): File " ", line 5, in File "lxml.etree.pyx", line 744, in lxml.etree._Element.remove (src/lxml/lxml.etree.c:32634) ValueError: Element is not a child of this node.
