replace-xpath

In a regex parser, replace the current "active" string with the result of the evaluation of an XPath expression.

Attributes

async (Boolean default: true) - Asynchronous processing. For parse tags, should the request be enqueued (false) or processed before its next sibling. For other elements, this attribute only makes a difference when they contain asynchronous requests which need to be processed before the element is processed. In this case, when false the element's next sibling will only be processed after the current element, when true Watson Explorer won't wait for the current element to be processed before processing its next sibling.
elt-id (Integer) - Usage: Internal
max-elt-id (Integer) - Usage: Internal
execute-acl (Text)
process (Text) - An XPath determining which of the attributes and/or children will be processed. Currently only "", "*", "@*" and "*|@*" are supported.
select (Text) - XPath expression. Usage: Must be specified once all the child elements have been processed

Children

Choose any number of these in any order.
- attribute: (Zero or more) - Set an attribute of the first parent element

Examples

Input Example:

<parser name="p">
<match token="ok">
<add-document/>
<replace-xpath select="concat('concat ', viv:current-string())"/>
<add-content name="c"/>
<add-processed-xsl to="document">
<xsl:template match="/">
<content name="d">
<xsl:value-of select="name(viv:current-node())"/>
<xsl:value-of select="viv:current-string()"/>
</content>
</xsl:template>
</add-processed-xsl>
</match>
</parser>
<parse parser="p">ok</parse>

Output Example:

<parser name="p">
<match token="ok">
<add-document/>
<replace-xpath select="concat('concat ', viv:current-string())"/>
<add-content name="c"/>
<add-processed-xsl to="document">
<xsl:template match="/">
<content name="d">
<xsl:value-of select="name(viv:current-node())"/>
<xsl:value-of select="viv:current-string()"/>
</content>
</xsl:template>
</add-processed-xsl>
</match>
