[REBOL] Re: Simple XML

From: joel:neely:fedex at: 9-Mar-2004 15:47

Hi, Terry, No script needed. PARSE-XML does what you're asking (given that you can use the block convention it creates -- see below). T. Brownell wrote:

>> block-stuff: parse-xml xml-stuff
== [document none [["root" none ["^/ " ["person" none ["^/ " ["name" none ["^/ " ["fname" none ["^/ Bob^/ ... The convention is that each XML element is represented by a 3-item block, containing: 1) the name of the element/tag as a STRING! 2) attributes (as a block of name/value pairs) or NONE if no attrs 3) contents (as a block of the content items -- strings for text and blocks for child elements) or NONE if no contents *AT*ALL* IgnorableWhiteSpace is not ignored, but appears as STRING! content. The entire XML string is wrapped in a mythical element whose tag is the WORD! DOCUMENT with no attributes. If you juat want the XML content, just take FIRST THIRD of the result of PARSE-XML, as in (the line breaks were added for email formatting, and should be eliminated if you try to cut and paste):
>> x: {<top><middle place='between'>
<bottom>down</bottom></middle></top>} == {<top><middle place='between'> <bottom>down</bottom></middle></top>}
>> print mold first third parse-xml x
["top" none [["middle" ["place" "between"] [["bottom" none ["down"]]]]]]
