xml - 如何设置正确的 xpath

Question

我想在 Keetle Spoon 中生成列表输出：

系统名称，产品名称

例子：

JOHN Adobe Reader XI (11.0.01)
JOHN D3DX10
JOHN Google Drive
JOHN Adobe Flash Player 11 ActiveX
JOHN Adobe Flash Player 11 Plugin

来自 xml 文件：

<computer>
 <system name="JOHN" />
 <operatingsystem name="Microsoft Windows 7 Professional " servicepack="Service Pack 1" />
 <windowscomponents>
  <component name="Windows Media Player (from Start Menu and Desktop)" class="2200" classname="" level="1" />
 </windowscomponents>
 <installedapplications>
  <msiapplication productname="Adobe Reader XI (11.0.01)" vendor="Adobe Systems Incorporated" version="11.0.01" installdate="20130111" />
  <msiapplication productname="D3DX10" vendor="Microsoft" version="15.4.2368.0902" installdate="20121219" />
  <msiapplication productname="Google Drive" vendor="Google, Inc." version="1.7.4018.3496" installdate="20130108" />
  <regapplication productname="Adobe Flash Player 11 ActiveX" version="11.5.502.146" />
  <regapplication productname="Adobe Flash Player 11 Plugin" version="11.5.502.146" />
 </installedapplications>
</computer>

我使用设置： Loop XPath /computer

领域：

1. system/@name
2. installedapplications/msiapplication/@productname
3. installedapplications/regapplication/@productname

但我只得到行：

JOHN Adobe Reader XI (11.0.01)
JOHN Adobe Flash Player 11 ActiveX

Answer 1

我对水壶勺的所有了解都来自于回答您之前的问题，但我相信您应该使用以下内容：

Loop XPath /computer/installedapplications/*

字段

../../system/@name
@productname
