XML Parser Stage

The XML parser stage parses whole XML documents by default, but it can also be configured to parse only specific nodes without loading the entire document into memory. It can also split an XML document into multiple documents. XPATH-like expressions are used to select specific nodes to parse, such as /posts/row or /posts/record. Nested XML elements are flattened.

To create new documents from selected elements, configure rootPaths.

Note
 The XML Transformation index pipeline stage is deprecated in favor of this parser stage.
Tip
 When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.

XML stage-specific properties

Property Description, Type
enabled

Enable this Parser Stage

type: boolean

default value: 'true'
errorHandling

Error Handling

type: string

default value: 'mark'

enum: { ignore log fail mark }
id

Parser ID

type: string

default value: '1ad0a5a7-65f6-46bc-954e-d1f50de2fb99'
ignoredMediaTypes

Media Types to ignore

Documents with a media type on this list will be not be processed by this parser stage.

type: array of string

inheritMediaTypes

Match default media types in this Parser Stage

Each parser stage has a built-in list of media types it handles by default. If this setting is true, that list will be used along with any optional additional types provided in the mediaTypes list. If this setting is false, this stage will only be selected for media types in the mediaTypes list, and the mediaTypes list becomes a mandatory property which must have at least one valid media type.

type: boolean

default value: 'true'
listHandling

XML List handling

Create a single multivalued field containing all items, or a separate index-numbered field per list item?

type: string

default value: 'multivalued'

enum: { multivalued index_numbered }
maxSize

Maximum output size for each document

Maximum number of XML characters, excluding extra whitespace, that will be processed from each source document node to produce an output document

type: integer

default value: '65536'
mediaTypes

Media Types to match

Documents with a media type on this list will be matched by this parser stage. See inheritMediaTypes / use default media types for more.

type: array of string

outputFieldPrefix

Prefix parsed fields with

Fields extracted by this parser will be prefixed with this string. The remainder of the field name will be as detected in the stream

type: string

maxLength: 20

pattern: ^$|^[A-Za-z_][A-Za-z0-9_\-\.]+$
pathPatterns

File names to parse

Specify a file name or pattern that must be matched for this parser stage to run. Forward slashes ("/") are used to join names of files inside archives with the archive name.

type: array of object

object attributes: {
  pattern : {
    display name: File name or pattern
    type: string
    description : e.g.: "z.txt" or "*.md" or "/a/*/b/f.txt" for glob; "z.txt$" or ".*\.txt$" or "^/a/[^\/]*/b/f.txt$" for regex
