# Extract Metadata

This section demonstrates how to extract metadata from an HTML page and add it to a document field.

Consider the following HTML:

    <h1>This is a title</h1>
    <h2>This is a sub-title</h2>
    <p class="important">This is <strong>important</strong> text</p>

From this HTML you could extract all of the headings and add them to a metadata field named `heading`. You could also extract the important text and add that to a separate document field.

The following configuration would extract the information described above:

    [WkoopHtmlExtractionTask]
    ...
    MetadataFieldSections0=ExtractHeadings
    MetadataFieldSections1=ExtractImportant

    [ExtractHeadings]
    MetadataSelector=h1,h2,h3
    MetadataFieldName=heading

    [ExtractImportant]
    MetadataSelector=p.important
    MetadataFieldName=important_paragraph
    MetadataExtractPlainText=TRUE

The configuration parameters `MetadataSelector` and `MetadataFieldName` select the information to extract and provide the name of the destination document field.

The parameter `MetadataExtractPlainText` specifies whether to extract as plain text (removing HTML markup, for example).

The configuration above would produce the following metadata fields:

    #DREFIELD heading="This is a title"
    #DREFIELD heading="This is a sub-title"
    #DREFIELD important_paragraph="This is important text"
