Xml Xpath检查值并选择子节点

我的wordpress导入遇到了以下情况。我需要的是选择 “ResourceLink”byt xpath。该映像与“ResourceContentType”相关。有可能在那里 是一个值01，但也是02（在节点排序中也是混合的）。我只需要'01'值，因此我需要在选择资源链接后检查此值

我给自己写了这句话

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

这是可行的，但当ResourceContentType=02作为第一个订购时，我得到了错误的图像。我需要补充一点 检查ResourceContentType=01的xpath代码中的某些内容

<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>

</ResourceLink>
<ContentDate>

<Date dateformat="00">20121214</Date>
</ContentDate>

您可以添加

ResourceContentType

如下检查：

{CollateralDetail[1]/SupportingResource[ResourceContentType='01'][1]/ResourceVersion[1]/ResourceLink[1]}
