# 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 configuration parameters `MetadataSelector` and `MetadataFieldName` select the information to extract and provide the name of the destination document field. These parameters must be set in numbered pairs (so that each `MetadataSelector` parameter has a matching `MetadataFieldName`). The `MetadataSelector` parameter accepts standard CSS2 selectors.

The following configuration would extract the information described above:

    MetadataSelector0=h1,h2,h3
    MetadataFieldName0=heading
    MetadataSelector1=p.important
    MetadataFieldName1=important_paragraph
    MetadataSelectorExtractPlainText=TRUE

The parameter `MetadataSelectorExtractPlainText` 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"
