Xpath检查值，并选择子节点

我坚持以下情况为我的WordPress导入。我需要的是选择'ResourceLink'byt xpath 。该图像与'ResourceContentType'相关。有可能是一个值01，但也是02（在节点顺序中也是混合的）。我只需要'01'的值，所以我需要检查这个值，并选择资源链接后。Xpath检查值，并选择子节点

我自己写了这个xpath行;

{CollateralDetail[1]/SupportingResource[1]/ResourceVersion[1]/ResourceLink[1]}

哪些工作，但是，当ResourceContentType = 02的顺序作为第一我得到了错误的形象。我需要在我的XPath代码添加的东西，以检查是否ResourceContentType = 01

<SupportingResource> 
<ResourceContentType>01</ResourceContentType> 
<ContentAudience>03</ContentAudience> 
<ResourceMode>03</ResourceMode> 
<ResourceVersion> 
<ResourceForm>02</ResourceForm> 
<ResourceVersionFeature> 
<ResourceVersionFeatureType>01</ResourceVersionFeatureType> 
<FeatureValue>D502</FeatureValue> 
</ResourceVersionFeature> 
<ResourceVersionFeature> 
<ResourceVersionFeatureType>02</ResourceVersionFeatureType> 
<FeatureValue>800</FeatureValue> 
</ResourceVersionFeature> 
<ResourceVersionFeature> 
<ResourceVersionFeatureType>03</ResourceVersionFeatureType> 
<FeatureValue>563</FeatureValue> 
</ResourceVersionFeature> 
<ResourceVersionFeature> 
<ResourceVersionFeatureType>04</ResourceVersionFeatureType> 
<FeatureValue>9789043026529_covr.jpg</FeatureValue> 
</ResourceVersionFeature> 
<ResourceVersionFeature> 
<ResourceVersionFeatureType>05</ResourceVersionFeatureType> 
<FeatureValue>.0572</FeatureValue> 
</ResourceVersionFeature> 
<ResourceLink> 
url 
</ResourceLink> 
<ContentDate> 
<ContentDateRole>01</ContentDateRole> 
<Date dateformat="00">20121214</Date> 
</ContentDate> 
</ResourceVersion> 
</SupportingResource>

您可以添加ResourceContentType检查这样的：

{CollateralDetail[1]/SupportingResource[ResourceContentType='01'][1]/ResourceVersion[1]/ResourceLink[1]} 
             ^notice this addition^^^^
