使用 Delphi 2010,我想使用 TXMLDocument 从以下 XML 示例数据(我省略了不需要的部分)中读取 Location、Smartcard_Location 和 Integrated_Location 的 URL:
<?xml version="1.0" encoding="UTF-8"?>
<PNAgent_Configuration xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">
<Request>
<Enumeration>
<Location replaceServerLocation="true" modifiable="true" forcedefault="false" RedirectNow="false">http://2003xa/Citrix/PNAgent/enum.aspx</Location>
<Smartcard_Location replaceServerLocation="true">https://2003xa/Citrix/PNAgent/smartcard_enum.aspx</Smartcard_Location>
<Integrated_Location replaceServerLocation="true">http://2003xa/Citrix/PNAgent/integrated_enum.aspx</Integrated_Location>
<Refresh>
<OnApplicationStart modifiable="false" forcedefault="true">true</OnApplicationStart>
<OnResourceRequest modifiable="false" forcedefault="true">false</OnResourceRequest>
<Poll modifiable="false" forcedefault="true">
<Enabled>true</Enabled>
<Period>6</Period>
</Poll>
</Refresh>
</Enumeration>
</Request>
</PNAgent_Configuration>
数据已经从网络服务器加载到 TXMLDcoument 中。解析这些数据并将 URL 转换为字符串值的最简单方法是什么?
