html - 选择后面的第一个标签使用 xpath 标记

Question

我有如下给出的 HTML：

<root>
 <Customer cid= "C1" name="Janine" city="Issaquah">
  <input name="Client.ClaimsAdjudicationPendReason" />
  <a onclick="javascript:pendReasonLookup('MFM_Pend Reason', 'PendReason','txtClaimsAdjudicationPendReason','','')>
            <img title="Lookup" class="imgSearchIcon" alt="Lookup" src="/F005web/images/search.gif"/>


<input name="Client.ClaimsAdjudication" />
    <a onclick="javascript:pendReasonLookup('MFM_Pend Reason', 'PendReason','txtClaimsAdjudication','','')>
            <img title="Lookup" class="imgSearchIcon" alt="Lookup" src="/F005web/images/search.gif"/>

  </Customer>  
</root>

使用下面的 xpath，我可以选择“输入”节点，其中

name="Client.ClaimsAdjudicationPendReason"

xpath:=//input[@name='Client.ClaimsAdjudicationPendReason']

但我需要选择img节点（就在a标签下方）

name="Client.ClaimsAdjudicationPendReason"

Answer 1

原始 html 缺少一些位，请参阅我上面的评论。因此，假设这是预期的：

<root>
    <Customer cid="C1" name="Janine" city="Issaquah">
        <input name="Client.ClaimsAdjudicationPendReason" />
        <a onclick="javascript:pendReasonLookup('MFM_Pend Reason', 'PendReason','txtClaimsAdjudicationPendReason','','')" />
        <img title="Lookup" class="imgSearchIcon" alt="Lookup" src="/F005web/images/search.gif" />
        <input name="Client.ClaimsAdjudication" />
        <a onclick="javascript:pendReasonLookup('MFM_Pend Reason', 'PendReason','txtClaimsAdjudication','','')" />
        <img title="Lookup" class="imgSearchIcon" alt="Lookup" src="/F005web/images/search.gif" />
    </Customer>
</root>

下面的 xpath 将选择 “Client.ClaimsAdjudicationPendReason”之后的第一个img节点inputname

//input[@name="Client.ClaimsAdjudicationPendReason"]/following-sibling::img[1]
