Question

我正在爲用戶使用JavaScript工具來檢索使用預定義值的搜索結果。其中一個預定義值包含一個包含＆符號的短語。我無法弄清楚如何格式化字符串，以便查詢Web服務將返回一個值。

var eventCat = "Conference & Events"; 
var dateQ = "(DateStart>='" + startDate + "' AND DateStart<='" + endDate + "') AND "; 
var eventQ = " EventCategory='" + eventCat + "' AND "; 
var q = "SELECT Title,Path,Description,Write,Rank,Size,DateStart,DateEnd,EventCategory,GroupOnly FROM SCOPE() WHERE "; 
q += dateQ + eventQ + " GroupOnly=false AND (\"SCOPE\"='Sales Marketing & Excellence Events')"; 

var queryText = makeQuery(q); 

makeQuery創建XML所需要查詢的Web服務，轉換＆符號來&，<到<和> >。

<QueryPacket xmlns='urn:Microsoft.Search.Query' Revision='1000'> 
    <Query> 
    <Context> 
     <QueryText language='en-US' type='MSSQLFT'> 
     SELECT 
      Title,Path,Description,Write,Rank,Size,DateStart,DateEnd,EventCategory,GroupOnly 
     FROM 
      SCOPE() 
     WHERE 
      (DateStart&gt;='2014-09-28T00:00:00Z' AND DateStart&lt;='2014-11-09T23:59:59Z') AND 
      EventCategory='Conference &amp; Events' AND 
      GroupOnly=false AND 
      ("SCOPE"='Sales Marketing & Excellence Events') 
     </QueryText> 
    </Context> 
    <IncludeSpecialTermResults>true</IncludeSpecialTermResults> 
    </Query> 
</QueryPacket> 

可正常工作時eventCat有一些其他的價值像所有的，但是當我把上面的查詢時，SharePoint返回錯誤：An error occurred while parsing EntityName。

我試過用各種替代方法替換＆符號，我所做的一切都沒有改變。什麼是正確的格式發送？

我想通了。我在查詢周圍添加了<[CDATA[。

<QueryPacket xmlns='urn:Microsoft.Search.Query' Revision='1000'> 
    <Query> 
    <Context> 
     <QueryText language='en-US' type='MSSQLFT'><[CDATA[ 
     SELECT 
      Title,Path,Description,Write,Rank,Size,DateStart,DateEnd,EventCategory,GroupOnly 
     FROM 
      SCOPE() 
     WHERE 
      (DateStart>='2014-09-28T00:00:00Z' AND DateStart<='2014-11-09T23:59:59Z') AND 
      EventCategory='Conference & Events' AND 
      GroupOnly=false AND 
      ("SCOPE"='Sales Marketing & Excellence Events') 
     ]]></QueryText> 
    </Context> 
    <IncludeSpecialTermResults>true</IncludeSpecialTermResults> 
    </Query> 
</QueryPacket>
