Question

我正在尝试解析xml并获取状态的值。为什么不打印状态？

我可能在代码中遗漏了什么？这是我的代码

XML

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<cluster_info>
    <nodes>
        <entry>
            <key>Standby stuff</key>
            <value>
                <available_versions>
                    <available_version>62</available_version>
                </available_versions>
                <current_version>62</current_version>
            </value>
        </entry>
    </nodes>
    <target_state>
        <available_versions>
            <available_version>62</available_version>
        </available_versions>
        <current_version>62</current_version>
    </target_state>
    <new_versions>
        <new_version>38</new_version>
        <new_version>37</new_version>
    </new_versions>
    <removable_versions />
    <state>STABLE</state>
</cluster_info>

Answer 1

XML中存在错误：

<state>STABLE</cluster>

应该是

<state>STABLE</state>

Answer 2

Fiddle

这项工作没问题。

$(xml).find('state').each(function () {
    $('body').text($(this).text());
});

在Ajax中解析xml响应无法正常工作
