Syntax

XMLAddChild(<XML document> , <Tag> [, <Tag value> [, <Change of position> [, <Option>]]])

<XML document>: Character string (with quotes)

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

<Tag>: Character string (with quotes)

Name of tag to add. If this parameter corresponds to the CDATA constant, the content of the CDATA tag will not be interpreted by the XML parser. You have the ability to include an image in binary format in this tag. Caution: the encoding used must respect the encoding of the XML document.
When using the CDATA parameter, a Buffer variable must be used.
Caution: You cannot create elements (tag or attribute) with accented characters.

<Tag value>: Optional character string (with quotes)

Value of new tag. This parameter corresponds to an empty string by default.

<Change of position>: Optional boolean

True to be positioned on the added element. In this case, the added element becomes the current position.
False (default value) to avoid modifying the current position during the addition.

<Option>: Optional Integer constant

Addition options. The possible values are:
XMLEncodingAmpersand If the "&" character (ampersand) is found in the value of added tag, it will be encoded in "&" format.
If this constant is not specified, the "&" character must be encoded in the XML tag. No encoding will be performed.

Remarks

Managing the addition

If the current position is an attribute, the new tag is added at the end of the current list of child tags for the tag that contains the attribute.
The current position in the document does not change during the call to XMLAddChild except if <Change of position> is set to True.

Note: XMLDocument creates no root for the document. To create a first child element in an empty document, this document must necessarily contain a root.

Saving the modifications in the XML file

To save the modifications performed in an XML file, you must:

Use XMLBuildString. This function retrieves and formats the content of an XML document.
Save the character string generated by XMLBuildString in an XML file. To do so, use fSaveText.

Example:

// Once the XML document was modified
XMLSource = XMLBuildString("XMLDoc")
// Save the XML file
fSaveText("ModifiedExample.xml", XMLSource)

XML functions and threads

If your application uses threads, the XML document is shared between all these threads. See Managing threads for more details.
