我们从Python开源项目中，提取了以下20个代码示例，用于说明如何使用xml.dom.replaceChild()。
def testLegalChildren(self): dom = Document() elem = dom.createElement('element') text = dom.createTextNode('text') self.assertRaises(xml.dom.HierarchyRequestErr, dom.appendChild, text) dom.appendChild(elem) self.assertRaises(xml.dom.HierarchyRequestErr, dom.insertBefore, text, elem) self.assertRaises(xml.dom.HierarchyRequestErr, dom.replaceChild, text, elem) nodemap = elem.attributes self.assertRaises(xml.dom.HierarchyRequestErr, nodemap.setNamedItem, text) self.assertRaises(xml.dom.HierarchyRequestErr, nodemap.setNamedItemNS, text) elem.appendChild(text) dom.unlink()
def testReplaceChildFragment(self): dom, orig, c1, c2, c3, frag = self._create_fragment_test_nodes() dom.documentElement.replaceChild(frag, orig) orig.unlink() self.confirm(tuple(dom.documentElement.childNodes) == (c1, c2, c3), "replaceChild(<fragment>)") frag.unlink() dom.unlink()
def testWholeText(self): doc = parseString("<doc>a</doc>") elem = doc.documentElement text = elem.childNodes[0] self.assertEqual(text.nodeType, Node.TEXT_NODE) self.checkWholeText(text, "a") elem.appendChild(doc.createTextNode("b")) self.checkWholeText(text, "ab") elem.insertBefore(doc.createCDATASection("c"), text) self.checkWholeText(text, "cab") # make sure we don't cross other nodes splitter = doc.createComment("comment") elem.appendChild(splitter) text2 = doc.createTextNode("d") elem.appendChild(text2) self.checkWholeText(text, "cab") self.checkWholeText(text2, "d") x = doc.createElement("x") elem.replaceChild(x, splitter) splitter = x self.checkWholeText(text, "cab") self.checkWholeText(text2, "d") x = doc.createProcessingInstruction("y", "z") elem.replaceChild(x, splitter) splitter = x self.checkWholeText(text, "cab") self.checkWholeText(text2, "d") elem.removeChild(splitter) self.checkWholeText(text, "cabd") self.checkWholeText(text2, "cabd")
def testPatch1094164(self): doc = parseString("<doc><e/></doc>") elem = doc.documentElement e = elem.firstChild self.confirm(e.parentNode is elem, "Before replaceChild()") # Check that replacing a child with itself leaves the tree unchanged elem.replaceChild(e, e) self.confirm(e.parentNode is elem, "After replaceChild()")
