如果PromotionType包含单词＆＃34; Discount＆＃34;但不是＆＃34;打折＆＃34;

Question

我需要XSLT的帮助。示例XML如下所示。

<offer>
    <Promotions>
        <Promotion sequenceNumber="5132">        
            <Amount>0</Amount>
            <PromotionType>Discount</PromotionType>        
            <PromotionLength>12</PromotionLength>
            <DiscountAmount>64</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="8400">        
            <Amount>0</Amount>
            <PromotionType>Discounted Price</PromotionType>
            <PromotionLength>6</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="5132">       
            <Amount>0</Amount>
            <PromotionType>Discount</PromotionType>
            <AssociatedCustomization>ATT-V5-HSIA-ULT-AI-VOIP-A</AssociatedCustomization>
            <PromotionLength>12</PromotionLength>
            <DiscountAmount>64</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="8400">        
            <Amount>0</Amount>
            <PromotionType>Discount + Reward Card or Amazon Prime</PromotionType>
            <PromotionLength>6</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>    
        <Promotion sequenceNumber="8400">        
            <Amount>0</Amount>
            <PromotionType>Discount + Reward Card or Amazon Prime</PromotionType>
            <PromotionLength>6</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="5132">        
            <Amount>0</Amount>
            <PromotionType>Discount or Device</PromotionType>        
            <PromotionLength>12</PromotionLength>
            <DiscountAmount>64</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="8400">        
            <Amount>0</Amount>
            <PromotionType>Discounted Price</PromotionType>
            <PromotionLength>6</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="9000">        
            <Amount>0</Amount>
            <PromotionType>Free Product</PromotionType>
            <PromotionLength>3</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
        <Promotion sequenceNumber="9000">        
            <Amount>0</Amount>
            <PromotionType>Free Product</PromotionType>
            <PromotionLength>3</PromotionLength>
            <DiscountAmount>0</DiscountAmount>
            <RewardCardAmount>0</RewardCardAmount>
        </Promotion>
    </Promotions>
    <StandardFees>
       <Fee>140</Fee>
       <FeeTerm>Monthly</FeeTerm>
       <Description>No term commitment required.</Description>
       <RackRate>199</RackRate>
       <DiscountedFee>189</DiscountedFee>
       <DiscountTerm>12</DiscountTerm>
       <ContractTerm>24</ContractTerm>
    </StandardFees>    
    </offer>

如果PromotionType包含单词＆＃34; Discount＆＃34;但不是＆＃34;打折＆＃34;然后我需要显示Offer / StandardFees / DiscountedFee else Offer / StandardFees / Fee。任何帮助都非常感谢。我需要在XSLT中执行此操作。
