JavaScript rescursive XML元素遍历

我的目的是使用递归方法查找给定xml的所有“文本节点”，例如，如果输入xml为：

    <foo>
        <bar>
            <a>1</a>
            <b>2</b>
        </bar>
    </foo>

上述方法在大多数情况下都能正常工作，但如果父节点具有某些属性或xsi类型，则会失败。例如，如果下面是我的输入xml：

    <soap:Envelope
        xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <soap:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <buyGuid>
                <Context>
                    <INFO>
                        <buyGuidRequest>
                            <Property xsi:type="PostalAddress">
                                <address>Some address</address>
                                <postcode>0000</postcode>
                            </Property>
                        </buyGuidRequest>
                    </INFO>
                </Context>
            </buyGuid>
        </soap:Body>
    </soap:Envelope>

某个地址
0000

---

它不会遍历到

或

的子级！！但是，如果我从

标记中删除

xsi:type

，它将正确地遍历到属性的所有子元素，并查找地址和zipCode。我不知道为什么会发生这种情况，以及xsi:type如何影响深度遍历？有人能解释一下这个问题吗？谢谢

您的输入似乎格式不正确，无法识别xsi前缀。删除该属性时会复制该行为

xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance"

从元素

某个地址
0000
什么是
xml
，字符串还是文档？您需要使用jQuery吗？@Bergi我已经更新了代码，但是
xml
指的是
xml=$.parseXML（我的输入xml）
