proc parse_data(response, element: string): seq[string] {...}{.
    raises: [IOError, OSError, ValueError, Exception, XmlError, RegexError],
    tags: [ReadIOEffect, RootEffect, WriteIOEffect].}

Takes XML as a string and an element name and returns the text nodes of each element as a sequence of strings.

Example:

let
      some_xml = """<?xml version="1.0" encoding="UTF-8"?><datastreamProfile  xmlns="http://www.fedora.info/definitions/1/0/management/"  xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.fedora.info/definitions/1/0/management/ http://www.fedora.info/definitions/1/0/datastreamProfile.xsd" pid="test:9" dsID="MODS"><dsLabel>MODS Record</dsLabel>

proc get_attribute_of_element(response, element, attribute: string): seq[string] {...}{.
    raises: [IOError, OSError, ValueError, Exception, XmlError, RegexError],
    tags: [ReadIOEffect, RootEffect, WriteIOEffect].}

Terrible code to try to find matching attribute values for nodes in a string of XML.

Example:

let
  some_xml = """<rdf:RDF xmlns:fedora="info:fedora/fedora-system:def/relations-external#" xmlns:fedora-model="info:fedora/fedora-system:def/model#" xmlns:islandora="http://islandora.ca/ontology/relsext#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
    <rdf:Description rdf:about="info:fedora/test:6">
    <islandora:isPageOf rdf:resource="info:fedora/test:3"></islandora:isPageOf>
    <islandora:isSequenceNumber>2</islandora:isSequenceNumber>
    <islandora:isPageNumber>2</islandora:isPageNumber>
    <islandora:isSection>1</islandora:isSection>
    <fedora:isMemberOf rdf:resource="info:fedora/test:3"></fedora:isMemberOf>
    <fedora-model:hasModel rdf:resource="info:fedora/islandora:pageCModel"></fedora-model:hasModel>
    <islandora:generate_ocr>TRUE</islandora:generate_ocr>
    </rdf:Description>
    </rdf:RDF>"""
  an_element = "fedora-model:hasModel"
  an_attribute = "rdf:resource"
assert get_attribute_of_element(some_xml, an_element, an_attribute) == @["info:fedora/islandora:pageCModel"]
  Source Edit 
proc get_text_of_element_with_attribute(response, element: string;
                                        attribute_with_value: (string, string)): seq[
    string] {...}{.raises: [IOError, OSError, ValueError, Exception, XmlError,
                       RegexError],
              tags: [ReadIOEffect, RootEffect, WriteIOEffect].}

Grabs text values of elements with associated attributes. Use with caution.

Example:

let
  some_xml = """<mods xmlns="http://www.loc.gov/mods/v3" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.loc.gov/mods/v3 http://www.loc.gov/standards/mods/v3/mods-3-5.xsd">
