MarkLogic 10 Product Documentationtde:validate
tde:validate( $templates as element(tde:template)*, [$excludeTemplateURIs as xs:string*] ) as map:map
Summary
In addition to
xdmp:validate
that can be used for validating against the extraction template schema.
The recommended workflow for users is to validate an extraction template before inserting it into the schema database. Unless you use the tde:template-insert function, Ill-formed templates are not validated or rejected at document insertion time.
For more information on extraction templates, see Template Driven Extraction (TDE) in the Application Developer's Guide.
Usage Notes
The tde:validate
function enables users to do the following:
- Check the template structure and format.
- Validate the XQuery val expressions.
- Check if the context expressions are legal.
- Validate against stored templates (for view declaration consistency and other features).
Example
xquery version "1.0-ml";
let $t1:=
<template xmlns="http://marklogic.com/xdmp/tde">
<context>/Citation/Article/Journal/Details</context>
<rows>
<row>
<schema-name>Medical</schema-name>
<view-name>Publications</view-name>
<columns>
<column>
<name>ID</name>
<scalar-type>BAD_SCALAR_TYPE</scalar-type>
<val>../../../ID</val></column>
</columns>
</row>
</rows>
</template>
return tde:validate(($t1),("previous_version_of_t1.xml"))
