ruby - Ruby - 字符串的正则表达式提取

Question

我正在尝试提取以下列方式格式化的字符串的内容：

    <script type="text/javascript">
                            document.viewData = THE INFORMATION I WANT 
</script> some other stuff

关于如何实施的任何想法？

提前致谢！

Answer 1

Your text data:

text = <<-_TEXT_
    <script type="text/javascript">
                            document.viewData = THE INFORMATION I WANT
</script> some other stuff
_TEXT_

Setup a regular expression

re = /document\.viewData = (.*)/

apply it to the text and get the result

result = (text.match re)[1]    
print result

Answer 2

require 'nokogiri'

doc = Nokogiri::XML::Document.parse <<-_XML_
<script type="text/javascript">
                            document.viewData = THE INFORMATION I WANT 
</script> some other stuff
_XML_

doc.at('//script').text.strip.split("=").last
# => " THE INFORMATION I WANT"

Answer 3

根据您的严格程度，这可以完成工作（匹配组中的结果）：

<script type="text\/javascript">\W+document.viewData =\s+([^<]+)\W+\s+<\/script>
