Syntax

<Result> = XMLWrite(<XML document> , <Path of element to create or modify> , <String to write>)

<Result>: Boolean

True if the element was created or modified,
False otherwise (the ErrorOccurred variable is set to True). To find out the error details, use ErrorInfo.

<XML document>: Character string (with quotes)

Name of the XML document into which the write operation must be performed. This document contains the XML code to study and it was created by XMLDocument.

<Path of element to create or modify>: Character string (with quotes)

Can correspond to:
the path of the value to read in the XML file. To write the value of an attribute, the name of the attribute must be preceded by the "@" character.
the text of an XPath query to run. The XPath query must be a query for "selecting records". If several elements match the selection, the first element found is used.
If this path does not start with "/", the name of the root node is automatically added. If the XML document has no root, <Result> will correspond to <Not found>.

<String to write>: Character string (with quotes)

String that must be written into the specified element.

Remarks

XMLWrite does not modify the current position in the document.
Several XML browse queries cannot be nested.
If a filter is used to create a second element, an error will occur if the first element does not exist.
Do:

XMLWrite("DOM", "Help/Function", "Example")
XMLWrite("DOM", "Help/Function[2]", "Example")

Don't:

XMLWrite("DOM", "Help/Function[2]", "Example")
