magic.lambda.xml

This project provides XML helper slots for Hyperlambda. More specifically, it provides the following slots.

• [xml2lambda] - Creates a lambda object out of an XML input string
• [lambda2xml] - Creates an XML string from a lambda object

How to use [xml2lambda]

.xml:@"<CATALOG>
  <PLANT>
    <COMMON>Bloodroot</COMMON>
    <BOTANICAL>Sanguinaria canadensis</BOTANICAL>
    <ZONE>4</ZONE>
    <LIGHT>Mostly Shady</LIGHT>
    <PRICE>$2.44</PRICE>
    <AVAILABILITY>031599</AVAILABILITY>
  </PLANT>
</CATALOG>
"
xml2lambda:x:@.xml

The above results in something resembling the following.

xml2lambda
   CATALOG
      PLANT
         COMMON
            #text:Bloodroot
         BOTANICAL
            #text:Sanguinaria canadensis
         ZONE
            #text:4
         LIGHT
            #text:Mostly Shady
         PRICE
            #text:$2.44
         AVAILABILITY
            #text:031599

Attributes starts out with the @ character, children nodes does not - While text content inside of elements will be named #text. This implies you’ll need to use escaped expression iterators when traversing the resulting node lambda object. For instance, to retrieve the above PRICE element’s inner text, you could use something such as the following.

get-value:x:@xml2lambda/**/PRICE/*/\#text

How to use [lambda2xml]

To convert from a lambda object to an XML object you can use something such as follows.

.xml
   CATALOG
      PLANT
         COMMON
            #text:Bloodroot
         BOTANICAL
            #text:Sanguinaria canadensis
         ZONE
            #text:4
         LIGHT
            #text:Mostly Shady
         PRICE
            #text:$2.44
         AVAILABILITY
            #text:031599
