    <p>I have a problem while validating XML against schema that uses regular expression. I'm using LibXML. Actually the libXML is used by PHP, but same problem, of course, occurs in the console. XML should be valid since I tested it with some online validators.</p> <p>Anyway workarounds? Modifying the schema is not a very good option because it's provided by a third party source.</p> <p>I'm using xmllint command with libXML versions 2.7.8 and 2.9.1. </p> <pre><code>xmllint: using libxml version 20708 compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude Iconv ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules Debug Zlib xmllint: using libxml version 20901 compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude Iconv ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules Debug Zlib </code></pre> <p><strong>Command I use:</strong></p> <pre><code> xmllint --noout -schema s x </code></pre> <p><strong>Errors I get:</strong></p> <pre><code>x:2: element testdate: Schemas validity error : Element 'testdate': [facet 'pattern'] The value '31.8.2013' is not accepted by the pattern '((([0-2]{0,1}[0-9]{1})|(3[0,1]{1}))\.((0?[1-9]{1})|(1[0-2]{1}))\.2[0-9]{3})?'. x:2: element testdate: Schemas validity error : Element 'testdate': '31.8.2013' is not a valid value of the atomic type 'mdatetype'. x fails to validate </code></pre> <p><strong>My XML file named 'x' is:</strong></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;testdate&gt;31.8.2013&lt;/testdate&gt; </code></pre> <p><strong>My schema named 's' is:</strong></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt; &lt;xs:element name="testdate" type="mdatetype"/&gt; &lt;xs:simpleType name="mdatetype"&gt; &lt;xs:restriction base="xs:string"&gt; &lt;xs:maxLength value="10"/&gt; &lt;xs:pattern value="((([0-2]{0,1}[0-9]{1})|(3[0,1]{1}))\.((0?[1-9]{1})|(1[0-2]{1}))\.2[0-9]{3})?"/&gt; &lt;/xs:restriction&gt; &lt;/xs:simpleType&gt; &lt;/xs:schema&gt; </code></pre> <p><strong>Edit</strong></p> <p>Some regular expressions work.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
