的Xpath不起作用

試圖拉從交通局狀態供稿一些數據 -的Xpath不起作用

<LineStatus ID="6" StatusDetails="Minor delays between Acton Town and Heathrow/Uxbridge due to an earlier faulty train at Holborn. GOOD SERVICE on the rest of the line."> 
<BranchDisruptions> 
    <BranchDisruption> 
    <StationTo ID="244" Name="Uxbridge"/> 
    <StationFrom ID="1" Name="Acton Town"/> 
    <Status ID="MD" CssClass="GoodService" Description="Minor Delays" IsActive="true"> 
     <StatusType ID="1" Description="Line"/> 
    </Status> 
    </BranchDisruption> 
    <BranchDisruption> 
    <StationTo ID="284" Name="Heathrow Terminal 5"/> 
    <StationFrom ID="1" Name="Acton Town"/> 
    <Status ID="MD" CssClass="GoodService" Description="Minor Delays" IsActive="true"> 
     <StatusType ID="1" Description="Line"/> 
    </Status> 
    </BranchDisruption> 
</BranchDisruptions>

只需使用XPath = // @名工作摳出來的數據在我們的標牌軟件的名稱元素，但我不知道如果父節點在<BranchDisruption>之下，節點將顯示出來。嘗試了很多組合沿線，

xpath=//@Name[not(ancestor::BranchDisruption)]

但沒有運氣。有沒有人有什麼建議？

父母下面沒有屬性爲'Name'的元素 – splash58

準確地寫出你想從示例中選擇的元素 – splash58

嗨splash58，抱歉，讀那個回來我遺漏了一些信息。你在哪裏有Name =「Uxbridge」，這對我很有用（代碼將'Uxbridge'拉出來，但如果它位於標籤下，我不希望它工作（頁面上的代碼更多 –

基於以下假設：它具有屬性Name的元素是BranchDisruption直接孩子總，我看到了下面的XPath的工作原理：

//@Name/parent::*/parent::*[not(name()='BranchDisruption')]/*/@Name

測試的XPath下面的xml：

<?xml version="1.0" encoding="UTF-8"?> 
<LineStatus ID="6" StatusDetails="Minor delays between Acton Town and Heathrow/Uxbridge due to an earlier faulty train at Holborn. GOOD SERVICE on the rest of the line."> 
<BranchDisruptions> 
    <BranchDisruption> 
    <StationTo ID="244" Name="Uxbridge"/> 
    <StationFrom ID="1" Name="Acton Town"/> 
    <Status ID="MD" CssClass="GoodService" Description="Minor Delays" IsActive="true"> 
     <StatusType ID="1" Description="Line"/> 
    </Status> 
    </BranchDisruption> 
    <BranchDisruption> 
    <StationTo ID="284" Name="Heathrow Terminal 5"/> 
    <StationFrom ID="1" Name="Acton Town"/> 
    <Status ID="MD" CssClass="GoodService" Description="Minor Delays" IsActive="true"> 
     <StatusType ID="1" Description="Line"/> 
    </Status> 
    </BranchDisruption> 
<Non-BranchDisruption> 
    <StationTo ID="284" Name="Heathrow Terminal 6"/> 
    <StationFrom ID="1" Name="Acton Town 7"/> 
    <Status ID="MD" CssClass="GoodService" Description="Minor Delays" IsActive="true"> 
     <StatusType ID="1" Description="Line"/> 
    </Status> 
    </Non-BranchDisruption> 
</BranchDisruptions> 
</LineStatus>

它會給：

Attribute='Name="Heathrow Terminal 6"' Attribute='Name="Acton Town 7"'
