asked on

is there a way i can read two attributes at the same time (XML)

below is my xml file and i am finding a efficient way to read.

i am after two Attributes

1) Title
2) TopicName

so in other words, if i pass the TopicName = "Marketing1" or "Coverage1" it should return me "Department1"

<content type="application/xml">
    <CatalogItems xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="sitename.xsd">
        <CatalogSource Acronym="ABC" OrganizationName="ABC Corporation" />
        <CatalogItem Id="3212" CatalogUrl="urlname">
            <ContentItem xmlns:content="sitename.xsd" Title="Department 1">
                <content:SelectionSpec ClassList="" ElementList="" />
                <content:Language Value="eng" Scheme="ISO 639-2" />
                <content:Source Acronym="ABC" OrganizationName="ABC Corporation1" />
                <content:Topics Scheme="ABC">
                    <content:Topic TopicId="1" TopicName="Marketing1" />
                    <content:Topic TopicId="11" TopicName="Coverage1" />
                </content:Topics>
            </ContentItem>
        </CatalogItem>
    <CatalogItem Id="3212" CatalogUrl="urlname">
        <ContentItem xmlns:content="sitename.xsd" Title="Department 2">
            <content:SelectionSpec ClassList="" ElementList="" />
            <content:Language Value="eng" Scheme="ISO 639-2" />
            <content:Source Acronym="ABC" OrganizationName="ABC Corporation2" />
            <content:Topics Scheme="ABC">
                <content:Topic TopicId="2" TopicName="Marketing2" />
                <content:Topic TopicId="22" TopicName="Coverage2" />
            </content:Topics>
        </ContentItem>
    </CatalogItem>
    <CatalogItem Id="3212" CatalogUrl="urlname">
        <ContentItem xmlns:content="sitename.xsd" Title="Department 3">
            <content:SelectionSpec ClassList="" ElementList="" />
            <content:Language Value="eng" Scheme="ISO 639-2" />
            <content:Source Acronym="ABC" OrganizationName="ABC Corporation3" />
            <content:Topics Scheme="ABC">
                <content:Topic TopicId="3" TopicName="Marketing3" />
                <content:Topic TopicId="33" TopicName="Coverage3" />
            </content:Topics>

I would do this by using XPATH with filter something like:
content/CatalogItems/CatalogItem/[CatalogItem/@TopicName="Marketing1"]/@Title

see examples for xpath
